Vertical flow wetlands as the core for the sustainable treatment of coffee wastewater in small communities in Colombia: preliminary results of the treatment of coffee wastewater in rural areas by vertical flow wetlands.

Coffee is one of the most important agricultural products in Colombia. To date, small-scale Colombian coffee growers have developed this activity with a simple infrastructure and random use of water that generates harmful by-products to the water resource mainly in the stage of separation of the mucilage. The coffee mucilage wastewater (CMW) is composed of high organic loads and its impact on water sources is due to its high load of nutrients such as nitrogen (N), phosphorus (P), and chemical oxygen demand (COD) values of over 25,000 mg/L. However, there is no consensus on what treatment can be used, especially whether it is accessible to coffee producers. Thus , the aim of this study consisted of assessing the performance of the combination of a carbon filter (CF) as pretreatment and vertical flow wetland (VFW) as a Natural-based Solution (NbS). The results show a reduction of more than 85% of COD, 96% of total solids, and UV254 close to 94%. It was remarkable that both treatments are appropriate for waters with a high concentration of solids. Finally, it can be concluded that CF + VFW is a feasible technology to treat the coffee wastewater from small communities of coffee producers.

The Natural Alternatives: The Impact of Plant Extracts on Snowbush (Breynia disticha Forst.) Cuttings’ Morpho-Physiological and Biochemical Characteristics

The utilization of cuttings remains a prevalent method for vegetative propagation in various plant species. Synthetic rooting hormones have conventionally been employed to enhance the rooting process; however, their high cost and potential environmental risks have necessitated the exploration of natural alternative compounds. In this study, the efficacy of natural plant extracts (pure honey, aloe extract, willow extract, moringa extract, and cinnamon powder) and synthetic auxin derivatives (indole-3-butyric acid and α-naphthaleneacetic acid) at a concentration of 2000 ppm was compared for their influence on rooting and vegetative growth of snowbush (Breynia disticha) cuttings, a significant ornamental and medicinal shrub. Results demonstrated that while the synthetic hormones produced the highest survival percentages and root number, the roots were consistently short, thick, friable, and largely void of secondary roots. Conversely, the alternative natural plant extracts, particularly aloe extract, exhibited promising outcomes, showcasing good rooting percentage and root number, significantly increased root length, and fresh and dry root weight. Furthermore, aloe extract demonstrated the potential to enhance shoot length and alter the chemical constituents of the cuttings. The highest values of total phenols and nitrogen percentage were recorded with cuttings treated with indole-3-butyric acid, followed by cuttings treated with aloe extract. While using aloe extract, we recorded the highest values of total carbohydrates, phosphorus, and potassium percentages. Notably, the highest endogenous levels of indole acetic acid and gibberellic acid, along with the lowest abscisic acid concentration in cutting tissues, were associated with the highest rooting percentage observed with indole-3-butyric acid, followed by the use of aloe extract. We hypothesized that natural plant extracts, specifically aloe extract, have potential as a viable alternative for synthetic auxins in promoting successful rooting and vegetative growth in snowbush cuttings. Further research is warranted to explore the underlying mechanisms and optimize the application of these natural compounds in vegetative propagation techniques.

County-Scale Spatial Distribution of Soil Nutrients and Driving Factors in Semiarid Loess Plateau Farmland, China

Characterized by a topography of thousands of ravines, the Loess Plateau has highly complex spatial variability in terms of soil nutrients. Therefore, it is of considerable importance to study the soil nutrient spatial distribution, driving factors of precise fertilizer management, and the strategic use of soil nutrient resources. In 2017, 242 soil samples were taken from the semiarid Anding district farming region in northern China. The spatial variability and factors influencing soil nutrients were studied using statistical and geostatistical methods. The results showed that the mean soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), available potassium (AK), and pH values were averaged at 12.64 g·kg−1, 0.84 g·kg−1, 23.20 mg·kg−1, 188.87 mg·kg−1, and 8.60, respectively. The nugget-to-sill ratios for the semi-variograms of SOM, TN, AP, and AK varied from 25.84 to 49.93%, while the coefficients of variation varied from 24.53 to 69.44%, revealing that all four indicators exhibited considerable variability, and that the samples’ geographical variability was produced by a combination of random and structural factors. Overall increasing trends were exhibited from the middle to the northeast and southwest in the distributions of SOM, TN, and AP. The spatial distribution of AK displayed the opposite trend, increasing from the southwest to north and southeast. The texture of the tillage layer was the main factor directly affecting SOM, and explained 8% of its variation. The distribution of TN was mainly influenced by the irrigation method and water source type. AP and AK contents differed significantly between the two parent materials, three textures, and three topography types at the level of p < 0.01. In conclusion, the regional soil fertility was poor, spatial heterogeneity was moderate, and influencing factors were complex, highlighting the need to adopt precise fertilization management and adopting land management measures according to the actual influencing factors of each nutrient, thereby contributing to the enhancement of regional fertility.

Dietary citric acid improves phosphorus and calcium availability and intestinal morphology of Nile tilapia Oreochromis niloticus

Citric acid is an organic acid, which has been used as a feed additive because it has a reasonable cost, pleasant taste, and fast assimilation, showing positive effects on the growth and health of some livestock and aquatic species. This study aimed to evaluate the effects of increased levels of citric acid (0, 10, 20, 30, and 40 g/kg) in an isonitrogenous (280.00 g/kg of digestible protein) and isoenergetic diet (12.98 MJ/kg of digestible energy) on growth performance, body composition, apparent digestibility of nutrients and minerals, hematology, pH in stomach and intestine, and intestinal histomorphometry of Nile tilapia juveniles. Fish (n = 200, initial average weight of 14.59 ± 0.81 g) were randomly distributed in 25 experimental tanks (five replicates per treatment) and fed experimental diets over a 40-day period. Increasing levels of citric acid supplementation resulted in a decrease in the pH of the experimental diets (P = 0.021). However, no significant differences in pH levels were observed in the stomach and intestine among the treatments (P > 0.05). Citric acid supplementation did not significantly (P > 0.05) affect the growth performance variables, body composition, or the apparent digestibility coefficients (ADC) of dry matter, crude protein, gross energy, ether extract, and ash of the diets. Fish fed diets with 10 and 30 g/kg citric acid exhibited higher values for total leukocytes (P = 0.043) and total plasma protein (P = 0.019) compared to the control group. Diets supplemented with 20 g/kg citric acid showed a higher ADC value for phosphorus (P = 0.027) and calcium (P = 0.032) compared to the control. Additionally, fish fed with diets containing 20 g/kg citric acid demonstrated higher values for villus height (P = 0.002) and width (P = 0.048), crypt depth (P = 0.035), and villus: crypt ratio (P = 0.014) compared to the control group. In conclusion, the supplementation of 20 g/kg citric acid improved the availability of phosphorus and calcium and positively influenced the intestinal morphology of Nile tilapia juveniles.

Phosphorus Sorption by Saline Soils of Western Transbaikalia

The sorption of phosphorus by salt marshes of the dry-steppe zone of the Republic of Buryatia from an aqueous solution of KN2PO4 in the concentration range from 0.25 to 5.0 mM/L (mmol/L) was studied under static conditions. The interaction time is 24 hours with a soil: solution ratio of 1 : 10. The amount of sorbed phosphorus was calculated from the difference in its content in the initial solutions and in the filtrates of soil suspensions. Based on experimental data, phosphorus adsorption isotherms were constructed by soil and sorption parameters were calculated using the Langmuir and Freundlich equations. Typical and quasi-clay Solonchaks have relatively high sorption properties with respect to phosphorus. The value of the maximum adsorption capacity (Amax) in the humus horizons of these soils varied in the range of 23.04–42.74 mM P/kg, in the underlying horizons 16.26–30.39 mM P/kg. In general, all soils, with the exception of the sorov Solonchaks, had an Amax value in the range of 17.70–42.74 mM P/kg. A low sorption value of phosphorus was found in the Solonchaks of sorovy. The Langmuir adsorption constant (KL) varied in the range of 0.3–14.0 l/mmol. Solonchaks dark and typical most strongly bind phosphorus. The Freundlich coefficient (KF) in the studied soils varied in the humus horizon from 5.34 to 63.43 mM P/kg, in mineral from 1.74 to 22.68 mM P/kg. The distribution coefficient (Kd) ranged from 1.95–145.04 l/kg with high values for quasi-clay Solonchaks and low for sorov Solonchaks. The correlation between Kd and Amax was estimated as average (r = 0.51), Kd and KL – high (r = 0.84, p ≤ 0.05). The studied soils according to the values of SPR (the amount of phosphorus that must be sorbed by the soil to maintain a concentration of P = 0.2 mg/kg (0.0065 mM/l) in soil solution) from (0.0723 to 3.4836 mM/kg) refer to weakly absorbing phosphorus. According to the ability to sorb phosphorus, soils form the following decreasing series: quasi-glay solonchaks typical solonchaks dark solonchaks glay solonchaks alluvial light humus saline sorov solonchaks.

Selection and Characterization of Phosphate-Solubilizing Fungi and Their Effects on Coffee Plantations.

The use of phosphate-solubilizing fungi in coffee cultivation is an alternative to the use of traditional fertilizers. The objective of this study was to analyze the mechanisms involved in the phosphorus solubilization of fungal strains and to evaluate the effect of a phosphate-solubilizing strain on coffee plants. For this, phosphorus-solubilizing fungal strains were selected for evaluation of their solubilization potential and phosphatase activity. Coffee plants were inoculated in the field with a phosphate-solubilizing strain, and the soil and foliar soluble phosphorus contents, as well as coffee bean yield, were quantified. Of the 151 strains analyzed, Sagenomella diversispora, Penicillium waksmanii, and Penicillium brevicompactum showed the highest solubilization. Aspergillus niger and P. waksmanii presented the highest soluble phosphorus values; however, P. brevicompactum showed the highest phosphatase activity. The P. brevicompactum strain inoculated on the coffee plants did not favor the foliar phosphorus content but increased the soil soluble phosphorus content in two of the coffee plantations. The plants inoculated with the phosphate-solubilizing strain showed an increase in coffee bean weight on all plantations, although this increase was only significant in two of the three selected coffee plantations.

Nutrient analysis of fermented chicken feather fertilizer waste using Bacillus subtilis on the growth of green spinach (Amaranthus tricolor)

Introduction: Farmers generally provide NPK chemical fertilizers (Nitrogen, Phosphorus, Potassium) to provide nutrients for green spinach plants. However, the use of NPK chemical fertilizers harms the environment. Nowadays, chicken feathers are known as beneficial for fertilizing plants, similar to NPK chemical fertilizers. Fermentation of chicken feathers by Bacillus sp. can improve the quality of protein in chicken feather fertilizers which can be used as a supplement in renewing soil conditions. Thus, this study is aimed to evaluate the nutrient component of fermented chicken feather fertilizer waste using Bacillus subtilis on the growth of green spinach (Amaranthus tricolor) Methods: This was a cross-sectional study. In this study, we used a total sampling technique. In this study, three groups got different chicken father fertilizers, and two groups of standard and did not get the chicken father fertilizer. Data from the research will be statistically analyzed descriptively. The descriptive data will provide in the table. Results: In the first treatment group, the value of nitrogen (N) was 2.439, phosphorus (P) was 2.225%, and potassium (K) was 2.408%. In the second treatment group, the nitrogen (N) value obtained 2.866%, the phosphorus (P) value was 2.174%, and the potassium (K) value was 2.477%. In the third treatment group, the nitrogen (N) value was 3.291%, the phosphorus value was 3.082 %, and the Potassium (K) value was 3.135%. Conclusion: According to the results, the higher the chicken feather fermented fertilizer dose, the higher the NPK content. This is certainly good for the growth of spinach.

Stoichiometric characteristics of woody plant leaves and responses to climate and soil factors in China.

The main research content of the field of ecological stoichiometry is the energy of various chemical elements and the interaction between organisms and the environment throughout ecological processes. Nitrogen and phosphorus are the main elements required for the growth and development of plants and these also form the constituent basis of biological organisms. Both elements interact and jointly regulate the growth and development of plants, and their element ratios are an indication of the nutrient utilization rate and nutrient limitation status of plants. Previous research developed a general biogeography model of the stoichiometric relationship between nitrogen and phosphorus in plant leaves on a global scale. Further, it was shown that the relative rate of nitrogen uptake by leaves was lower than that of phosphorus, and the scaling exponent of nitrogen and phosphorus was 2/3. However, it is not clear how the stoichiometric values of nitrogen and phosphorus, especially their scaling exponents, change in the leaves of Chinese woody plants in response to changing environmental conditions. Therefore, data sets of leaf nitrogen and phosphorus concentrations, and nitrogen to phosphorus ratios in Chinese woody plants were compiled and classified according to different life forms. The overall average concentrations of nitrogen and phosphorus in leaves were 20.77 ± 8.12 mg g-1 and 1.58 ± 1.00 mg g-1, respectively. The contents of nitrogen and phosphorus in leaves of deciduous plants were significantly higher than those of evergreen plants. In leaves, life form is the main driving factor of nitrogen content, and mean annual temperature is the main driving factor of phosphorus content; soil available nitrogen is the main driving factor of the nitrogen to phosphorus ratio. These values can be used for comparison with other studies. In addition, the scale index was found to be significantly different among different life forms. The scaling exponents of N-P of woody plants of different life forms, such as trees, shrubs, evergreen, deciduous, and coniferous plants are 0.67, 0.72, 0.63, 0.72, and 0.66, respectively. The N-P scaling exponent of shrubs was higher than that of trees, and that of deciduous plants was higher than that of evergreen plants. These results suggest that the internal attributes of different life forms, the growth rate related to phosphorus, and the relative nutrient availability of soil are the reasons for the unsteady relationship between nitrogen and phosphorus in leaves.

PARATHYROIDECTOMY IN PATIENTS WITH HYPERPARATHYROIDISM

Aim: The aim of this study was to analyze all the factors (disease symptoms, sinthigraphic findings, biochemical parameters) that occur in patients with hyperparathyroidism, and since hyperparathyroidism itself is a common endocrine disorder. Methods: We analyzed 79 patients with primary, secondary, and tertiary hyperparathyroidism, who underwent surgery. We analyzed mean of age, male: female ratio, representation of different forms of hyperparathyroidism. In our study, we examined the indications for examination and surgery, as well as the most common symptoms and comorbidities. For localization PTG, scintigraphy was performed by a nuclear medicine specialist (at the Clinic of Radiology and Nuclear Medicine) preoperatively. Preoperative values of calcium (Ca), phosphorus (P), and parathyroid hormone (PTH) were determined in all patients, and the same values were measured postoperatively. We also analyzed correlation of dialysis length and parathyroid gland hyperplasia in patients with secondary hyperparathyroidism. Results: In our study mean of years was 51.13 ± 11.83 and most of the respondents were female. The most common operation was subtotal parathyroidectomy. The most common indication for examination of parathyroid glands (PTG) was renal failure. The most common comorbidity was arterial hypertension, which was found in 43 (53.2%) subjects, and the rarest gastrointestinal diseases and pancreatitis, in 1 (1.3%) patients. Scintigraphy showed an equal representation of enlarged lower parathyroid glands (both right and left). The mean values determined preoperatively for PTH were 796.24 pg/ml, Ca 2.58 mmol / l and P 1.35 mmol / l. The mean postoperative values for PTH were 222.33 pg/ml, Ca 2.06 mmol/l and P 1.17 mmol/l. We also showed that was a large correlation between dialysis length and hyperplasia. Conclusion: Hyperparathyroidism is a common endocrine disease, carrying potential complications of many organic systems. In most cases, regardless of the form (primary, secondary, or tertiary), it ultimately requires surgical treatment. For this reason, the clinical picture must be well known, the necessary preoperative diagnostic methods (which are complex), all with the aim of better effect of treatment of such patients.

Evaluation of factors affecting treatment and mortality in patients over 65 years of age and without chronic disease, followed in the Intensive Care Unit due to COVID-19.

In this study, demographic, clinical, and laboratory data of patients aged 65 and over who are followed on mechanical ventilators due to COVID-19 in intensive care clinics will be useful in terms of strategies to be developed in the fight against COVID-19 and other infectious agents. Our study included 299 patients aged 65 years and older, who were not chronically ill, and who were followed up on mechanical ventilators due to COVID-19 in intensive care clinics in the period between 2020 and 2022. Our study was designed as a retrospective cross-sectional study. The demographic characteristics of the patients included in the study, their complaints during hospitalization, the time between the beginning of the complaint and the admission to the hospital, the vital signs at the time of admission to the hospital, the lung computed tomography findings during hospitalization, and the treatments given were examined. 55.9% of all patients were males, and the mean age was 75.45±7.47 years. While there was no significant difference in terms of mean age between the groups of patients with/without a higher risk of mortality, there was a significant difference in gender (p=0.025). There was a statistically significant difference between the COVID-19 intensive care (p=0.001) and renal failure (p=0.014) and mortality groups. The mean nutric score, Procalcitonin (PCT), Lactate Dehydrogenase (LDH), Blood Urea Nitrogen (BUN), Phosphorus, and lactate values, which are important parameters, were statistically higher in the group with a higher risk of mortality (p<0.001). In addition, there was a statistically significant difference in terms of sepsis, neuromuscular blocker (Nmb), vasopressor, and intubation between the groups of patients with/without a higher risk of mortality (p<0.001). In the group with high mortality, 34.2% (n=55) had plasmapheresis treatment, and 14.2% had hemodiafiltration treatment (p<0.001). According to the results of the multivariate logistic regression model in determining the factors associated with a higher risk of mortality, those who were males (p=0.001), those with kidney failure (p<0.001), those with organ failure (p=0.006), increased in alanine aminotransferase (ALT) values (p=0.019), those with sedation (p=0.001) and those with vasopressors (p<0.001) were found to have an increased risk of mortality. We think that our study is valuable in terms of determining the most appropriate treatment strategies by following the patients in terms of parameters that are significant in the findings during their follow-up period in the Intensive Care Unit.

Phosphate kinetic modeling as an estimate of daily ingested phosphate in hemodialysis patients with or without residual kidney function.

Daugirdas suggested a 2-pool phosphate kinetic model based on his previously established urea kinetic model. The current study aims to assess the level of agreement between the modeled daily ingested phosphorus (DIP) values and the routine method of dietary recall calculations in hemodialysis patients. The study was conducted on 100 hemodialysis patients; 50 were anuric, and the others had residual kidney function (RKF). The level of correlation and agreement between the dietary calculated and modeled DIP were assessed in both study groups. A statistically significant positive correlation existed between the calculated and modeled DIP (r = 0.79 for the anuric group, r = 0.84 for the RKF group, p < 0.001). There was a significant level of agreement between calculated and modeled DIP in RKF patients only. These findings suggest that phosphate modeling can estimate phosphate intake in RKF patients and be cost-effective in their management.

Dynamics of the wetland ecosystem health in urban and rural settings in high altitude ecoregion

The focus of the present study was to assess the dynamics of wetland ecosystem health in both urban and rural settings situated in the high-altitude Kashmir Himalayan ecoregion. The basic aim was to identify the drivers responsible for wetland degradation in order to sustain ecosystem services effectively. To achieve this, we examined water quality, trophic status, fish species diversity and human disturbances by analyzing changes in land use and land cover (LULC) since 1980. For the limnological characterization of the two wetlands, we evaluated a total of 21 physico-chemical parameters at 24 sites. Two-way analysis of variance revealed significant (p < 0.05) spatial and temporal variability in the water quality parameters. The trophic state index values of 67.7 and 76.7 indicated that the rural and urban wetlands were in eutrophic and hypertrophic status, respectively, signifying potential environmental stress. The data on fish fauna indicated a decline in fish species over the past 40 years, particularly the schizothoracine species. Urban wetlands showed a more significant decrease in species (06) compared to rural wetlands (01). LULC mapping and change analysis employing the visual interpretation technique showed significant transformations in the immediate catchment of wetlands. Substantial growth in the built-up (433.2 % and 2620 %) and decrease in aquatic vegetation (−83.4 % and − 97.5 %) in the immediate catchment was recorded in both the urban and rural wetlands respectively from 1980 to 2020. Our findings demonstrated a relationship between LULC classes and water quality parameters, with an increase in built-up and road areas showing a significant positive correlation with the rise in decadal mean values of total phosphorus, orthophosphorus, nitrate nitrogen, ammonical nitrogen, and calcium content. Based on these observations, we concluded that changes in land use and land cover within the immediate catchment areas of the wetlands were the primary drivers responsible for the deterioration of wetland ecosystem health.

Assessment of Fermented Rice Straw as Nutritive Substances for Bio-based Plant Pot

This research aims to develop bio- based nurseries or plant pots that contain soil nourishment from agricultural waste, namely rice straw. Tapioca starch glue as a binder was mixed with rice straw and then pressed by a hydraulic compression machine to form the sheet. To promote soil nourishment, the straw was fermented. The fermentations with and without enzyme assistance were compared as well as the fermentation time. The tensile strength of the specimens was assessed through a tensile test, revealing a surprising increase in strength with fermentation. The key distinction between the specimens with and without enzyme assistance was the time it took to reach the maximum value. Without the presence of enzyme, the specimens reached a maximum tensile strength of 0. 67 MPa after 7 days of fermentation. For fermentation with enzyme assistance, this value increased to 0. 81 MPa but required 14 days of fermentation to reach its maximum point. Not only the fermentation duration but also the inclusion of enzymes showed a slightly impact on water absorption and water swelling. Spectrophotometry was employed to analyze the value of phosphorus ( P) and potassium ( K) , while the amount of nitrogen ( N) was determined by the Kjeldahl method. As expected, soil nourishment can be promoted by fermentation and boosted by enzymes. The sheet from straw fermented with the enzyme at 21 days gives thehighest soil nourishment, i.e., 17.90%w/w for total K2O, 0.40%w/w for total P2O5, and 1.89%w/w for total N.

Risk factors associated with the development of secondary hyperparathyroidism in dialysis patients.

Aim To determine risk factors associated with the development and severity of secondary hyperparathyroidism in dialysis patients. Methods A cross-sectional study at the Clinical Centre of the University of Tuzla (March 2022) included 104 adult patients (males 51.9%, females 48.1%) with chronic kidney diseases under dialysis treatment. Based on parathyroid hormone (PTH) values, patients were divided into two groups: study group (45/104, PTH >792pg/mL) and control group (59/104, PTH 176-792 pg/ mL). The analysis aimed to resolve whether there was a connection between the duration of dialysis, the type of therapy treatment administered, the underlying kidney disease, and the presence of comorbidities with the values of PTH, and a wide spectrum of monitored laboratory parameters. Results The most common causes of chronic renal failure were undefined kidney diseases (32.7%), followed by diabetic nephropathy (18.3%) and chronic glomerulonephritis (16.3%). In the examined biochemical parameters, a significant difference was found in mean values of alkaline phosphatase (p<0.001). The correlation was proved between the duration of dialysis (p=0.028), the values of phosphorus (p=0.031), and alkaline phosphatase (p<0.001) with absolute values of PTH. The most common present comorbidity was hypertension (78.8%), followed by cardiovascular diseases (40.4%) and diabetes (22.1%). Conclusion A number of factors contribute to the development and severity of SHPT. Modulation of therapy and better control of risk parameters can prolong and reduce the frequency of SHPT in dialysis patients, as well as the occurrence of comorbidities.

Hybrid electrocoagulation reactor for dairy wastewater treatment and methodology for sludge reusability for the development of vermicompost.

The dairy industry is a high-water-consuming sector, making water conservation crucial, especially in countries like India that are top milk producers and have large populations. This research evaluates the performance and effluent characterization of dairy effluent treatment systems in Kerala using modern, cost-effective technology to address this issue. A hybrid electrocoagulation reactor (HECR) is designed to operate simultaneously in coagulation, and the electrocoagulation process is proposed in this study. The wastewater treatment parameters of the HECR with those of six existing dairy effluent treatment plants using geological mapping and geographic information system (GIS) were studied. According to inverse distance weighted (IDW) interpolation findings, HECR's effluent treatment profile is comparable to existing technologies, with a minimum required retention time of 9.58 h. The results show the HECR treatment efficiency, removing up to 75.15% of turbidity and 94.5% of COD. Moreover, the sludge generated from HECR is transformed into nutrient-rich vermicompost by adding suitable fillers in the ratio of 5:1:3:1 (industrial dairy sludge/HECR sludge: cow dung, dry leaf, and seed vermicompost). The optimal conversion times for vermicompost developed from dairy industrial sludge are 40 days, with nitrogen, phosphorus, and potassium (NPK) values per gram vermicompost of 8.86%, 3.18%, and 3.6%, respectively. For HECR sludge, on the 60th day, the observed NPK value for the developed vermicompost is at 4.76%, 1.46%, and 5.1%. Overall, this research offers a promising solution to treat dairy wastewater and transform generated waste sludge into a valuable resource, highlighting the importance of technology adaptation in the dairy industry.

Spatial heterogeneity in summer phytoplankton communities shaped by anthropogenic and natural effects in typical coastal bay-river systems in South China

Phytoplankton community spatial scales vary in typical coastal bay-river systems under natural and anthropogenic effects. However, their relative importance in shaping phytoplankton spatial heterogeneity has been largely uncharacterized in the literature. In this study, we performed comprehensive analyses using field monitoring, meteorological, and remote sensing datasets from a coastal bay-river system in South China (the Guangdong-Hong Kong-Macao Greater Bay-Pearl River tributaries) to examine phytoplankton spatial heterogeneity and main effects. We showed that water quality in the four water bodies of the typical coastal bay-river system in South China were relatively poor. Phytoplankton community abundance, taxonomic grouping, dominant species, and species similarity varied significantly in response to environmental gradients. We showed that Cyanophyta, Bacillatiophyta, and Chlorophyta were dominant phyla, and we observed regional variations in taxonomic groups and dominant species. Phytoplankton abundance was significantly higher in Dongjiang River and water bodies in branched bays when compared with other regions due to nutrient input from extensive agricultural and urban development, where the dominant phylum was Cyanophyta. Cyclotella (Bacillariophyta) had relatively high abundance and was widely distributed throughout the coastal bay-river system, except in the Dongjiang River. Melosira (Bacillariophyta) had relatively high abundance in Dongjiang and Xijiang Rivers, Merismopedia (Cyanophyta) dominated in the Dongjiang River and highly urbanized branched bay areas, while Microcystis (Cyanophyta) only dominated in Beijiang and Xijiang Rivers. Dominant species distributions showed apparent spatial heterogeneity in phytoplankton community composition. Species similarities between different water bodies were generally low, but phytoplankton species similarities between the Dongjiang River and water bodies in the branched bay area were relatively high, which indicated that water exchange associated with freshwater and nutrient inputs may have profoundly influenced species dispersal and dominant phytoplankton species. Redundancy analyses (RDA) demonstrated that pH, elevation, photosynthetically active radiation (PAR), dissolved active phosphorus (SRP), total dissolved phosphorus (TP), total nitrogen (TN), and nitrate nitrogen (NO3−-N) values - associated with nutrient and climate indicators were the main factors explaining structured phytoplankton spatial distributions. Variance partitioning analyses (VPA) showed that phytoplankton community variations were explained by anthropogenic factors (eutrophication) in summer. Our study improves our understanding of the natural and anthropogenic effects on phytoplankton spatial heterogeneity and provides basic study data for long-term phytoplankton evolution from river to bay areas.

STATUS UNSUR HARA MAKRO PADA INCEPTISOL YANG DITANAMI PAKCOY (Brassica rapa L.)

One of the activities of cultivating pakcoy (Brassica rapa L.) requires soil that has good fertility. One of the important soil fertility parameters for pakcoy plant growth is the availability of macro nutrients. Inceptisol is a soil that is quite extensive and has the potential to be developed but has problems in soil fertility. The purpose of this study was to determine the macronutrient status of inceptisol planted by pakcoy. The research was conducted in Kertanegla Village, Bojonggambir District, Tasikmalaya Regency, in January-February 2022. The method used in this study was a descriptive quantitative analysis of macro nutrients from soil analysis results. The results showed that the measured value for nitrogen was 0.1%, phosphorus value was 21.00 mg 100 g-1, and potassium was 41.00 mg 100 g-1. Based on these values, the macronutrient status at the study site, namely the nutrient status of nitrogen, was low, phosphorus was medium, and potassium was high.

The Effect of Temperature and Calcium Cloride Extract on Zinc Desorption in Changed Calcareous Soils

Zinc desorption studied for ten soils was variance in calcium carbonate, clay percent, and organic matter from Duhok province in the north of Iraq involved (Bamarny, Zawita Assih, Semeel, Kanimasi-1& 2, Khanke, Zakho, Batofa, and Faydi, locations). Soil testers after air dried up ground and filtered through a 2-mm sieve was taken to know the properties of the soils, zinc forms and desorption. Results showed the soluble, available, exchangeable and zinc total alternated among (0.29 - 0.94), (0.88 - 1.64), (1.71 - 2.05), and (12.25 - 56.15) mg.kg−1 one-to-one, Zn desorption raise with the raising of Zn added to research soils, extraction concentration CaCl2 from 0.1 to 1 molarity and temperature. Higher quantity of Zn release at 298K, was found in the soil of Kanimassi-1 (31.40 - 264.81) μg. g−1 at 0.1M, 1M CaCl2 extraction respectively, it may be owing to the high value of available phosphorus, CEC and organic matter and lower quantity of available-Zn and CaCO3. But the lowest amount observed in Faydi soil (14.10-118.69) μg. g−1. The high desorption of Zn at 321K, noted in Faydi soil between (50.50 - 421.00) μg. g−1 and low amount in Semeel soil between (26.35 - 222.10) μg.g−1 at 0.1 to 1M CaCl2 extraction respectively, designated Zn released more with increasing temperature. In general low quantity of Zn releases as of all researched soils causes to the great amount of CaCO3, quality and amount of clay minerals dominant that cause raise Zn bonding also low desorption from all studied soils. The effect of CaCl2 extraction concentration to increase Zn desorption was more than the effect of temperature in all soils.
