Effect of lime on soil chemical properties and corn growth in Ultisols Lebak, Banten

Abstract The research aimed to study the effect of lime on soil chemical changes and corn growth in Ultisol Lebak, Banten. The soil used is acidic mineral soil with a pH of 4.8 and a high exchangeable (exch) Al content of 6.3 cmolc kg−1. The research design used was a completely randomized design with 6 treatments of lime doses with 5 replications. The dose of lime applied is based on exch Al namely 0, 0.5; 1.0; 1.5, and 2.0 equivalent to 0, 3, 6, 9, and 12 t ha−1, respectively, and 1.0 exch Al of fosfatan. The results showed that lime application improved soil chemical properties as reflected by increasing soil pH, exch Ca, Mg, cation exchange capacity (CEC), base saturation (BS), and decreasing Al content and saturation. In addition, lime application increases the delta of soil pH. Soil acidity (pH) increased from 4.8 to 6.3; exch Ca levels increased from 1.61 to 12.77 cmolc kg−1, exch Mg levels increased from 0.78 to 0.88 cmolc kg−1.

Application of zinc modified biochars to enhance zinc availability, speciation and bajra growth in Zn-deficient soil

Zinc deficiency poses a serious threat to numerous crops and global human populations. Recently, soil biochar amendment has being promoted as a sustainable farming method. However, its consequence on the bioavailability of Zn in cereal crop has not been fully addressed. In the present study, 0.01% Zn-SO4 (w/w) was loaded in fruit waste, farmyard manure and coconut shell pyrolysis at 400 ℃, for 2 h to make fruit waste Zn-modified biochar (FWZn-MBC), farmyard manure Zn-modified biochar (FYZn-MBC) and coconut shell Zn-modified biochar (CSZn-MBC). Except control treatment, all the modified biochars were applied at 1, 2 and 4% doses on zinc availability, speciation, bajra growth and chemical properties in Zn-deficient soil. The obtained results showed that Zn mobility in soil was 70.04% with application of FYZn-MBC 4% as compared with other treatments. The maximum uptake of Zn in shoot and root by bajra plant was observed by 74.02% and 53% with addition of FYZn-MBC 4% as compared with control soil, due to an increase of soil organic matter. The chlorophyll SPAD values in the bajra aerial surface was increased from 30.23 to 39.24 with application FYZn-MBC 4% than control. The exchangeable fraction of Zn was increased from 7.34 to 14.71% with application of FYZn-MBC 4%. The correlation matrix results indicated that CaCO3 was positively correlated with soil pH. Soil organic matter was highly significant correlated with chlorophyll. Overall, future studies must be carried out to examine the long-term impact of FYZn-MBC 4% on Zn phytoavailbility in Zn-deficient soil.

Green manuring improves soil quality, grain yield, and grain anthocyanin content in colored rice cultivated in tropical regions

AbstractGreen manuring is the process by which vegetative crops are incorporated into the soil, and it plays a good substitutable role in reducing chemical fertilizer applications while enhancing soil fertility. Field experiments were conducted at Lingao City of Hainan Province in 2020 and 2021, to evaluate the effects of in situ incorporation of different green manures (fallow (as control), rice, sesbania, and stylosanthes) on soil physical and chemical properties, nitrogen (N) uptake, grain yield, and the grain anthocyanin content in colored rice. Treatments included colored rice cultivated with previous fallow (T0), with previous rice straw manure (T1), with previous sesbania manure (T2), and with previous stylosanthes manure (T3). The seedlings of the colored rice variety Suixiangheinuo were transplanted 23 days after the incorporation of green manure. Our results indicated that both the grain yield and grain anthocyanin content of colored rice were significantly increased when green manure was incorporated into the soil compared to that of the control. Therein, grain yields of T1, T2, and T3 were increased by an average of 12.7%, 29.0%, and 24.5%, respectively, across 2 years in comparison with those of T0. And grain anthocyanin content in colored rice under T1, T2, and T3 was increased by 7.2%–7.5%, 13.9%–24.2%, and 9.8%–20.6%, respectively. In addition, in situ incorporation of leguminous green manure in the soil significantly increased soil fertility and partial factor productivity for N fertilizer. The above results suggested that colored rice crops should be followed in rotation with leguminous green manure, which was beneficial to increasing both grain yield and grain anthocyanin content of colored rice. This research elucidated that the incorporation of leguminous green manure sustained the production of colored rice in tropical regions, which was beneficial to reconcile the relationship between rice production and environmental protection.

Overview of the Impact of Compost on Bulk Density, Aggregate Consistency and Cation Exchange Capacity of Soils and its Consequential Effect on Crop Productivity

Organic fertilizers offer several advantages over chemical fertilizers and are an environmentally friendly alternative that could help sustainably farmed land. Reviewing indigenous knowledge of the agronomic applications of organic manure and its possible contribution to agricultural growth was the goal of this article. It is evident that organic manures from various plant and animal sources can be used to satisfy certain field needs. However, the use of organic manures is still primarily conventional since they have not been well received by agricultural strategies. When bulky organic manures are directly applied to soil, they accelerate mineralization and reduce the rate at which nutrients, especially nitrogen, are released. Compared to raw resources, which have limited value and certain disadvantages, composting these wastes appears to offer significant potential. The majority of researchers verified that adding compost might enhance the soil's organic matter content, nutrient status, and physical, chemical, and biological properties. Soil organic matter concentrations rise in every long-term compost treatment study. But since they contain more stable carbon than fresh or immature composts, mature composts raise Soil organic matter considerably more effectively. Furthermore, because compost has so many beneficial effects on the physical, chemical, and biological aspects of soil, it helps to stabilize and improve crop quality and yield. As a result, the majority of studies have demonstrated that compost has an equalizing influence on seasonal and annual variations in soil temperature, air, water, and plant nutrient availability, as well as crop yields. mostly due to the nutrients' gradual release and availability in compost-combined fertilization techniques, which frequently yield positive outcomes. Therefore, composting can be a useful choice for building effective plant-nutrient management methods in many settings for sustainable agricultural systems within small-scale farming in impoverished nations.

Evaluation of Aggregate Stability Using the Slaking Index Method with Soil Physical Approach in Keduang Sub-Watershed, Indonesia

The Keduang Sub-Watershed area has faced multiple natural disasters like landslides, erosion, and flooding because of the poorly managed terrain in the area. This study examines the distribution of the slaking index on agricultural land in the Keduang Sub-Watershed, analyzes the impact of soil type on it, and identifies the soil physical elements that have the most significant influence on it. The study took place in the Keduang Sub-Watershed, Indonesia, utilizing agricultural land from woods, plantations, drylands, and paddy fields with Andisols, Alfisols, Inceptisols, and Entisols soil types. This survey research was supported by laboratory analysis of the soil's physical and chemical properties and used GIS for data interpretation. Soil samples were collected from 22 Land Map Units (LMUs) with 3 replications each, resulting in 66 samples. The SLAKES software assesses the primary parameter, the slaking index. The supporting parameters analyzed were aggregate stability, bulk density, texture, structure, pH, organic C, and Cation Exchange Capacity (CEC). The research showed that soil types in the Keduang Sub-Watershed significantly affect the slaking index value. The slaking index ranged from 0.13-11.63, with the highest values for Andisols in a forest, while the lowest values were Inceptisols in a plantation. The allophane mineral in Andisols was causing the high slaking index. The soil factors determining the slaking index were bulk density and exchangeable K. The lower the bulk density, the higher the slaking index. Meanwhile, the lower the exchangeable K, the lower the slaking index. The land management recommendations based on determinant factors are adding organic material and reducing soil cultivation practices.

The application of organic liquid fertilizer C. glomerata and NPK Phonska to enhance agronomic efficiency in maize cultivation on Alluvial soil

<p>Fertilization is crucial in maize cultivation, and inorganic fertilizers can be expensive. Therefore, it is essential to provide alternative fertilizers to reduce dependence on inorganic fertilizers. This study investigated the role of organic liquid fertilizer <em>C. glomerata</em> (OLFC) in increasing the efficiency of NPK Phonska fertilizer, influencing soil chemical reactions, and enhancing the growth and yield of maize on alluvial soils. The materials used were hybrid maize of the Pioneer 32, OLFC, and NPK Phonska (15-15-15). The experiment was arranged in a completely randomized design (CRD) in factorial. The OLFC was applied at 0 mL L<sup>-1</sup>, 5 mL L<sup>-1</sup>, and 10 mL L<sup>-1</sup>; NPK Phonska Fertilizer at 0, 150, and 300 kg ha<sup>-1</sup> in three replications. The data obtained were statistically analyzed using ANOVA at 5%. Level of significance and mean separation using the LSD at 5% probability. The following parameters were evaluated: soil chemical properties and agronomic factors, such as the height of crop, net assimilation rate, relative growth rate, weight of 100 seeds, yield, and agronomic efficiency (AE). The highest maize yield recorded was 4.83 tons per hectare, achieved by applying 150 NPK Phonska kg per hectare, supported by a fertilization efficiency of 11.28%. Adding 5 mL per liter of OLFC every two weeks to maize plants resulted in the highest AE, reaching 21.81%.</p>

Growth of Rubber Seeds (Hevea brasiliensis Muell.Arg) from Sleeping Eye Stum by Applying Organic Fertilizer Bulk and Liquid Herbal Waste

The organic fertilizer derived from herbal medicine waste in both bulk and liquid form is rich in macro and micro nutrients as well as decomposing microbes and probiotic bacteria needed to improve soil chemical properties. These fertilisers can be used to obtain better growth of rubber seedlings, especially rubber seedlings of sleeping eye origin. The objectives of this study was(1) to determine the effect of organic fertilizer and liquid bulk herbs Against Waste growth and (2) to know nutrient uptake of N, P, and K seedling stum Sleep eye. The study was conducted in a 4 x 3 factorial experiment arranged in a completely randomized design (CRD) with five replications. The first factor is the concentration of organic liquid fertilizer consisting of four in the standard: h0 = 0 ml L-1 of air (0%); h1 = 2 ml L-1 air (0.2%); h2 = 4ml L-1 air (0.4%); h3 = 6ml L-1 air (0.6%). The second factor is the dose of organic fertilizer consists of three levels: (b0 = 0 mg ha-1: b1 = 5 mg ha-1: b2 = 10 Mg ha-1). Data were analyzed with Analysis of Variant and continued with Duncan's Multiple Range Test 5% level. The results showed that the dosage of bulk organic fertilizers was significantly different at the level of 5% of the uptake of nitrogen, other observations were not significantly different. While the treatment of liquid organic fertilizer was highly significantly different at the level of 1% of nitrogen absorption, other observations were not significantly different. No real effect on their interaction in all observations. The treatment dose of organic fertilizer 5 Mg ha-1 and the treatment of liquid organic fertilizer 4 ml L-1 provided the highest results in leaf area of 586.46 cm2 per plant compared to the control treatment of 181.06 cm2 per plant. The treatment of bulk organic fertilizer dose and liquid organic fertilizer concentration predicted P2O5 nutrient uptake per rubber plant did not show significant differences. While the treatment of doses of bulk organic fertilizer and concentrations of liquid organic fertilizer is thought to be potassium nutrient uptake per rubber plant does not show significant differences, but can be seen from the growth of diameter, number of leaves, and leaf area.

Tomato yield and soil chemical properties influenced by low–molecular–weight organic acids in calcareous soil

<p>Calcareous soils have restrictive characteristics that limit and pose a challenge for crop production; in this environment, plants can exude low-molecular-weight organic acids (LMWOAs). This study aimed to verify the influence of exogenously applied LMWOAs in calcareous soils on tomato yield and the chemical characteristics of soil and leachate. <em>Solanum lycopersicum</em> L. seedlings were grown in pots containing calcareous soil in a greenhouse, fertilized by drip irrigation with Steiner nutrient solution in which the treatments 0.1 mM citric acid (CA), 0.1 mM oxalic acid (OA), 0.01 mM salicylic acid (SA) and a control without LMWOAs (T0) were prepared, applied during the whole growth cycle. The experiment was repeated four times, with twenty replicates per treatment, under a completely randomized design. The yield per plant was quantified, while pH and microbial respiration (RMS) were measured in the soil. The pH, electrical conductivity (EC), oxidation-reduction potential (ORP), carbonate (CO<sub>3</sub><sup>2–</sup>), and bicarbonate (HCO<sub>3</sub><sup>–</sup>) contents were quantified in the leachates. SA application reduced the soil pH (8.75). SA and CA improved the fruit yield per plant by 11% and 33%, respectively (p < 0.05). CA induced a 1.7% reduction in leachate pH (p < 0.05) and a 15.9% increase in HCO<sub>3</sub><sup>–</sup> content (p < 0.05). SA decreased EC and CO<sub>3</sub><sup>2–</sup> concentrations by 8.9 and 23.1% (p < 0.05), but increased HCO<sub>3</sub><sup>–</sup> content by 23.1 % (p < 0.05). The use of LMWOAs as a strategy in the management of calcareous soils can promote favorable conditions for tomato yield per plant.</p>

The study of the chemical properties of gray tereskenes ceratoides latens

Today, perennial plants of the natural flora are a raw material resource for the production of drought-resistant and heat-resistant feeds, among which Eurotia Ceratoides occupies a special place. In this work, the chemical properties of Eurotia Ceratoides latens (J.F. Gmel) were studied, the humus content in the soil was determined, and the chemical and physico-chemical properties of light gray soil (humus, water, carbonate ions, nitrogen) were revealed. The humus content was determined based on the oxidation of organic carbon with chromic acid to carbon dioxide. The chemical composition of Eurotia Ceratoides Latens was analyzed for the content of nutrients in the plant (protein, fiber, fat, nitrogen-free extractables, ash) and water-soluble substances (C, CO2, Ca, Mg). It was found that the ash content in plants almost does not change in the phases of vegetation with the age of plants and ranges from 9,11-10,05%, respectively, and the calcium content was at the level of 3,67- 4,90. The content of «crude» fiber was determined using the Soxlet apparatus, the content of calcium cations in the soil was evaluated by the complexometric method, and the Kjeldahl method was used to determine crude protein, crude fat by ether extraction, nitrogen-free extractives in ash by precipitation with a saturated solution of ammonium oxalate, and phosphorus by the colorimetric method. The nutritional value of Eurotia Ceratoides latens has been revealed.

Effects of coagulation pre-treatment on chemical and microbial properties of water-soil-plant systems of constructed wetlands

Chemical coagulation has gained recognition as an effective technique to enhance the removal efficiency of pollutants in wastewater prior to their entry into a constructed wetland (CW) system. However, its potential impact on the chemical and microbial properties of soil and plant systems within CWs requires further research. This study investigated the impact of using ferric chloride (FeCl3) as a pre-treatment stage for dairy wastewater (DWW) on the chemical and microbial properties of water-soil-plant systems of replicated pilot-scale CWs, comparing them to CWs treating untreated DWW. CWs treating amended DWW had better performance than CWs treating raw DWW for all water quality parameters (COD, TSS, TP, and TN), ensuring compliance with the EU wastewater discharge directives. Soil properties remained mostly unaffected except for pH, calcium and phosphorus (P), which were lower in CWs treating amended DWW. As a result of lower nitrogen (N) and P loads, the plants in CWs receiving FeCl3-amended DWW had lower N and P contents than the plants of raw DWW CWs. However, the lower loads of P into amended DWW CWs did not limit the growth of Phragmites australis, which were able to accumulate trace elements higher than CWs receiving raw DWW. Alpha and Beta-diversity analysis revealed minor differences in community richness and composition between both treatments, with only 3.7% (34 genera) showed significant disparities. Overall, the application of chemical coagulation produced superior effluent quality without affecting the properties of soil and plant of CWs or altering the functioning of the microbial community.

Diversity of soil fungi and entomopathogenic fungi in subtropical mountain forest in southwest China

AbstractTill now, the diversity of entomopathogenic fungi in subtropical mountain forest was less studied. Here, the vertical distribution of forest soil fungi, entomopathogenic fungi, and their environmental influencing factors in a subtropical mountain in western China were investigated. Soil samples were collected from four elevations in a subtropical forest in Shaanxi. The results indicated a greater richness of soil fungi at middle elevations and soil fungi were more even at low elevation. Soil pH, available iron, available potassium, total potassium, and available zinc were the most important influencing factors affecting this vertical distribution of fungi. Interestingly, the Isaria genus was predominant while Metarhizium and Beauveria showed decreasing abundance. The presence of Isaria showed a significant positive correlation with both total phosphorus and available iron, while, available zinc was negatively correlated. Metarhizium was influenced by elevation, pH, available phosphorus, and available copper and Beauveria was influenced by soil organic carbon, total nitrogen, total potassium, available potassium, and available zinc. Overall, as environmental factors affecting soil fungi, elevation, and plant species diversity were less important than soil physical and chemical properties. The virulence of isolated entomopathogenic fungi were tested against larvae of Tenebrio molitor, with mortality ranging from 31.11% to 100%. The above findings provide valuable data to deepen our understanding of the diversity of entomopathogenic fungi in subtropical mountain forests.

Evaluation of the Fertility Status of Rice Fields in Giri Jaya Village, Nagrak District, Sukabumi Regency

The research comprises three stages, which include: Field research, Laboratory research, encompassing the analysis of soil chemical properties. Data analysis, conducted both descriptively and quantitatively. Composite soil samples from rice fields were collected at three different elevations (top, middle, and bottom) at a depth of 1-20 cm in the surface layer of the rice field soil. Analysis of paddy soil samples involved measuring pH H2O using the electrometric method, total N, and cation exchange capacity (CEC) using the titrimetric method, potential K2O using the flame photometric method, potential P2O5 and organic C using the spectrophotometric method, K exchangeability and Na exchangeability using the flame photometric method, and Ca exchangeability and Mg exchangeability using the AAS method. Data obtained from soil analysis at different elevations were compared based on soil type for each observed parameter. The research results indicate that the evaluation of nutrient status is influenced by altitude. Land situated at lower elevations exhibits better soil fertility status, followed by land at the upper and middle elevations.

Iron biogeochemical redox cycling dominantly controls cadmium availability in acidic paddy soils

Periodic redox condition changes in acidic paddy soils substantially induce the biogeochemical redox cycling, and consequently affect Cd availability. However, the underlying biogeochemical mechanisms of the complicated redox processes in paddy soil remain poorly understood. Thus, we investigated the dynamics of Cd fractions under anoxic (0–40 days) and oxic (40–55 days) conditions. The available Cd content was evaluated using the diffusive gradients in thin film (DGT) technique, and the results show it decreased from 6.3 μg L–1 to below 0.1 μg L–1 under anoxic conditions, but rapidly increased to 13.5 μg L–1 under oxic conditions. Both sequential extraction procedures and X-ray absorption spectroscopy (XAS) analyses found that majority of available Cd transformed to organic matter complex and Fe-Mn oxides fractions, rather than bounded with sulfides. The soil chemical properties further evaluated, and the correlation analysis and principal component analysis results suggested that the key factors in soils for the available Cd was the SO42–, pH, and surface site concentration. The reduction of SO42– could generate sulfides which may precipitate with dissolved Cd. The biogeochemical redox cycling of Fe/N/S determined the changes of soil pH and consequently influenced adsorption behavior of Cd. The breakdown of the soil aggregations changed the surface site concentration, which may affect the immobilization of Cd. A process-based kinetic model was established, and it found that iron biogeochemical redox cycling dominated the changes of soil pH, and thereby contributed to majority Cd retention by Fe-Mn oxides (34.4 %) and organic matter (33.7 %). In addition, sulfur biogeochemical redox cycling only contributed to 13.6 % of the total Cd contents, because of relatively low Cd solubility in contaminated soils and the competition with other cations for limited sulfides. The findings provide robust targets for interpreting the iron and sulfur biogeochemical processes for Cd availability and would be helpful for developing the precise and effective remediation strategies in Cd-contaminated soils.

Dependency of Long-Term Soil Quality Controls on Summer Fallow Tillage and Soil Layers for Dryland Winter Wheat in Loess Plateau

The capacity for winter wheat to produce sufficient yield may be influenced by soil tillage practices and soil quality. However, determining how to quantify the impact of long-term tillage on soil quality is crucial. Here, we address this issue by comparing soil properties and wheat yield under four tillage systems during summer fallow in the Loess Plateau. Twenty-two soil properties were explored to estimate soil quality. Results showed that a rotational tillage (PT/ST) during summer fallow decreased soil bulk density (ρb) and improved soil gravimetric water content (θg), soil organic carbon (SOC), soil capillary porosity (Pc), and total porosity (Pt) in 0–50 cm soil layers. A minimum dataset (MDS) of thirteen indicators was selected to calculate soil quality index (SQI). Treatment of PT/ST had higher SQI value in soil layers of 0–10 cm and 20–50 cm, and PT/ST showed a significant increase in yield since the third year. No tillage (NT) during summer fallow decreased soil physical and chemical indicators, thus decreasing soil quality. These findings suggest that a rotation tillage of PT/ST during summer fallow could enhance soil chemical and biological properties concurrently, and PT/ST may provide a promising management strategy to sustain soil quality and grain yield for dryland winter wheat in the Loess Plateau.

Effect of slope, aspect, and position on soil properties at various depths in an oil palm plantation in Selangor, Malaysia

Abstract. Abdalrahem OMI, Ismail MH, Zaki PH, Singh DSAK. 2024. Effect of slope, aspect, and position on soil properties at various depths in an oil palm plantation in Selangor, Malaysia. Biodiversitas 25: 2507-2514. Limited information exists regarding the study of land and topographic characteristics and their influence on palm oil yield, as well as the effects on the physio-chemical properties of the soil. This study examined the impact of slope, aspect, and position at different soil depths on the physical and chemical properties of an oil palm (Elaeis guineensis Jacq.) plantation in an oil palm plantation in Selangor, Malaysia. Two sites with distinct north and south aspects were chosen for each slope site. Three equal positions were identified within each slope: Summit, Sideslope, and Toeslope. Random sampling determined soil physical and chemical properties at two depths (0-20 cm, 20-40 cm). This study analyzed soil chemical properties, including pH, EC, total N, P, Ext K, Ca, Mg, and soil texture, and the soil properties across different slope positions, depths, and aspects results indicated a significant difference (p<0.05). The soil properties' main factors contributing to the observed variations were slope position and soil depth. Slope position had a significant effect (p<0.05) on soil pH, EC, Ca, Mg, K, and N. Soil depth significantly influenced (p<0.05) all soil properties examined. The slope aspect also significantly affected (p<0.05) pH, Ca, Mg, and K. The soil texture classification ranged from sandy clay to sandy clay loam. Sand constituted the highest proportion of soil particles in both aspect slopes, followed by clay. The clay content increased with depth, specifically in the 20-40 cm range.
