A Review on the Improvement of Saline-alkali Soil by Organic Fertilizer

In recent years, soil salinization has become a serious problem in the global environment. The application of organic fertilizer to improve saline-alkali soil has been widely concerned because of its advantages of improving soil fertility, improving soil structure and improving soil salt ion composition. This paper reviews the mechanism of saline-alkali soil improvement, and expounds the improvement prospect of organic fertilizer on saline-alkali soil from the influence of organic fertilizer on soil physical and chemical properties, water and salt transport law, crop yield and quality, in order to provide theoretical guidance for saline-alkali soil restoration.

Vegetable and fruit wastes: Valuable source for organic fertilizer for effective growth of short-term crops: Solanum lycopersicum and Capsicum annum

Agriculture plays a vital role in the food security and economies of Asian countries. Annually, numerous metric tons of vegetable and fruit wastes are disposed of. This research aimed to convert the food wastes encompassing the vegetable and fruit wastes into solid and liquid organic fertilizer and to evaluate their influence on the growth (germination, phytochemicals, and biomolecules) of Solanum lycopersicum and Capsicum annum. Solanum lycopersicum, known as tomato, and Capsicum annum, known as bell pepper or chili pepper, are globally significant crops valued for their medicinal properties and economic importance. The pot experiment was performed with organic fertilizers (solid and liquid organic fertilizer) and compared with the influence of chemical fertilizer and control soil without fertilizers. Interestingly, the liquid organic fertilizer effectively enhanced the biometric profile and chlorophyll content of S. lycopersicum and C. annum Viz., 1.23 mg g−1 and 0.89 mg g−1, respectively. The results of a 30-days pot experiment with various fertilizer treatments showed significant influence of liquid organic fertilizer on the fresh and dry weight biomass of both S. lycopersicum and C. annum. Subsequently, the solid organic fertilizer showed considerable influence on test crops, and the influence of these organic fertilizers was more significant than the chemical fertilizer on crop growth in 30-days experiment. These results suggest that the sustainable approach can effectively convert vegetables and fruit waste into valuable organic fertilizer enriched with plant growth supporting essential nutritional elements.

Influence of organic fertilization on growth and yield of strawberry (Fragaria × ananassa) in Kabete and Mbooni areas, Kenya

Strawberries are a valuable crop in Kenya with the potential for significant economic contributions. However, strawberry production in the country has been facing considerable challenges, impacting its economic potential. This study examined the influence of organic manure on strawberry growth and characteristics in Kabete and Mbooni areas in Kenya. The study used a randomized complete block design (RCBD) with three replications. Treatments included livestock manure (well composted mixture of chicken, goat, and cow manure), bokashi manure, and a control, coded as LivManure, BokManure and Control, respectively. Growth parameters including leaf area, number of white flowers and number of runners, as well as yield parameters such as the number and weight of strawberries were assessed from the 3rd to 10th week after transplanting, during the short rain season of 2021. Using R statistical software, linear models were fitted to datasets from both study sites and analyzed using one-way ANOVA, followed by post-hoc tests for multiple comparisons. The rigorous analysis of the Kabete and Mbooni datasets provided insightful revelations about the influence of different treatments on strawberry characteristics, and geographical disparities between the two regions. The analysis of variance (ANOVA) outcomes unveiled significant treatment effects in both sites, with F(2,69) = 62.57, p < 0.001 for Kabete and F(2,69) = 49.02, p < 0.001 for Mbooni, highlighting distinct influences of treatments on log values within each group. Post hoc analyses, including Tukey tests and bootstrap comparisons robustly validated the significant differences among the three treatments in each site, supported by p-values <0.001. Effect sizes were also employed to reinforce the findings, and planned contrasts were set to gain more power in the analysis of variance. Comparison between Kabete and Mbooni indicated a significant difference of 9.78 units, with Mbooni area exhibiting significantly higher strawberry characteristics compared to Kabete. The results showed that LivManure treatment had the highest mean in both sites, followed by BokManure and Control treatments, respectively. These findings have important implications for agriculture, and highlight the potential benefits of using LivManure treatment to improve strawberry characteristics in similar agroclimatic settings. These observations can be attributed to the beneficial effects of livestock manure on soil health, which include buffering of the soil reaction, provision of essential plant nutrients and enhancement of soil faunal activities. Balanced use of livestock manure is recommended to enhance soil macro and micronutrients, and soil reaction for improved growth and yield of strawberry.

Influence of Organic Fertilization and Soil Tillage on the Yield and Quality of Cold-Pressed Camelina [Camelina sativa (L.) Crantz] Seed Cake: An Alternative Feed Ingredient

Camelina [Camelina sativa (L.) Crantz] oilseed cake has been identified as an alternative protein feedstuff and as a valuable feed resource. Moreover, over the last decades, there has been an increased interest in the organic production of feed supplements. A 2-year field experiment was conducted in a split-plot design with three replications, two main plots (conventional tillage: moldboard ploughing at 25 cm followed by rotary hoeing at 10–15 cm, and minimum tillage: chiseling at 25 cm depth followed by rotary hoeing at 10–15 cm), and three sub-plots (organic fertilization type: untreated, vermicompost, and compost) to evaluate the fertilization and tillage system effect on the yield and quality of cold-pressed camelina seed cake. Seed yield and cake yield were only affected by organic fertilization, with the highest values observed in the compost treatment. Crude protein was influenced by both factors examined, and the greatest content was found under conventional tillage and compost application. As for the fatty acid composition of oilseed cake, this can be characterized as a major source of polyunsaturated fatty acids (~52% of total FAs), particularly linoleic acid and α-linolenic acid, which were only affected by fertilization, with the highest values found after compost application. To conclude, the cold-pressed cake from camelina seed cultivated under compost fertilization and conventional tillage appears to be an effective alternative to conventionally used protein feed ingredients.

Influence of organic fertilization on clay mineral transformation and soil phosphorous retention: Evidence from an 8-year fertilization experiment

Organic fertilizer can improve phosphorus (P) bioavailability, while the mechanism of microbial-driven clay mineral transformation on P retention and utilization with organic fertilization is still unclear. An 8-year organic fertilization experiment was carried out in saline alkaline paddy soil with five treatments: (1) CK, no fertilization; (2) NK, mineral N and K fertilization; (3) NPK, NK with mineral P fertilization; (4) NPKC1, NPK with 450 kg C ha−1 year−1; (5) NPKC2, NPK with 900 kg C ha−1 year−1. The results showed that, compared with NPK treatment, the percentage of illite with more P adsorption sites was increased by 26.8% and 20.7% in NPKC1 and NPKC2 treatments, respectively. Meanwhile, transmission electron microscopy-energy dispersive X-ray spectroscopy analysis further confirmed that there was more P adsorption on silicate clay minerals. Compared with NK treatment, the content of total P and available P was significantly increased with organic fertilization. Besides, the diversity of bacterial community was also increased by organic fertilizer addition, redundancy analysis showed that soil organic carbon was the main factor in the diversity of bacterial community. The relative abundance of Firmicutes and Gemmatimonadetes was promoted, which drove the transformation of clay minerals and improved P availability, respectively. Compared with NPK treatment, P use efficiency in NPKC1 and NPKC2 treatments was increased by 47.2% and 58.2%, respectively, while no significant difference was found between the two treatments. Therefore, appropriate organic fertilization was a better fertilization practice to improve P retention and utilization through bacteria-driven clay mineral transformation in saline-alkaline paddy soil.

Effects of Organic Fertilizer Application on Tomato Yield and Quality: A Meta-Analysis

Tomatoes are a globally cultivated and popular vegetable. The output and quality of tomatoes are significantly influenced by the use of organic fertilizers. It was discovered that organic fertilizers increase tomato productivity and improve fruit quality. The influence of organic fertilizers on tomato yield and quality is shown to be complex and dependent on soil organic matter, total soil nitrogen, organic fertilizers kinds, and other variables. In this review paper, we evaluated 769 data sets from 107 research papers and determined that organic fertilizers can enhance the tomato yield by 42.18%. Compared to the control group, soluble solids, soluble sugar, lycopene, vitamin C, and nitrate were raised by 11.86%, 42.18%, 23.95%, 18.97%, and 8.36%, respectively. In general, the soil organic matter &gt;20 g·kg−1 and organic fertilizers significantly improved the tomato sugar/acid content ratio and VC, whereas under total soil nitrogen &gt;1 g·kg−1, organic fertilizers had significant differences in tomato soluble solids, soluble sugar, lycopene, and vitamin C, with different organic-fertilizer types having different effects on tomato quality. When comparing animal and plant organic fertilizers to other forms of organic fertilizers, we observed that tomato quality varied significantly. We also evaluated the impact of different cultivation methods, soil organic matter, total soil nitrogen, soil pH, and types of organic fertilizers on the tomato yield and quality. The results gave valuable information and direction for the use of organic fertilizers in greenhouse production.

Soil Chemical Properties Depending on Fertilization and Management in China: A Meta-Analysis

The long-term overuse of fertilizers negatively affects soil chemical properties and health, causing unsustainable agricultural development. Although many studies have focused on the effects of long-term fertilization on soil properties, few comparative and comprehensive studies have been conducted on fertilization management over the past 35 years in China. This meta-analysis (2058 data) evaluated the effects of the fertilizer, climate, crop types, cultivation duration and soil texture on the soil chemical properties of Chinese croplands. NPKM (NPK fertilizers + manure) led to the highest increase in pH (−0.1), soil organic carbon (SOC) (+67%), total nitrogen (TN) (+63%), alkali-hydrolysable nitrogen (AN) (+70%), total phosphorus (TP) (+149%) and available potassium (AK) (+281%) compared to the unfertilized control, while the sole nitrogen fertilizer (N) led to the lowest increase. The SOC (+115%) and TN (+84%) showed the highest increase under the influence of NPKM in an arid region. The increase in the chemical properties was higher in unflooded crops, with the maximum increase in the wheat–maize rotation, compared to rice, under NPKM. The SOC and TN increased faster under the influence of organic fertilizers (manure or straw) compared to mineral fertilization. Fertilizers produced faster effects on the change in the SOC and TN in sandy loam compared to the control. Fertilizers showed the highest and lowest effects on change in pH, organic C to total N ratio (C/N), TP and TK in clay loam with the cultivation duration. NPKM greatly increased the C/N compared to NPK in an arid region by 1.74 times and in wheat by 1.86 times. Reaching the same SOC increase, the lowest TN increase was observed in wheat, and the lowest increase in TP and AK was observed in rice, compared to the other crops. These results suggest that organic fertilizers (manure or straw) play important roles in improving soil fertility and in acidification. NPKM greatly increased the potential for soil C sequestration in wheat and in the arid region. The small increases in TP and TK can increase the SOC in rice and in the humid region. Therefore, considering the crop types and climatic conditions, reduced fertilization and the combination of mineral fertilizers with manure may be the best ways to avoid agricultural soil deterioration and increase soil carbon sequestration.

Enhancing soil fertility and lowbush blueberry (Vaccinium angustifolium) growth using bio-organic fertilizer

Acid soils contain high concentrations of aluminum and ferrous ions, which limit crop growth and the available plant nutrients. The current work was to determine the effects of bio-organic fertilizer (BOF) application on soil quality and the growth of blueberry cultivated in acid soil. A completely randomized block design was arranged, with four doses of BOF (0, 2, 4, and 6 t ha–1 yr–1). Each treatment was carried out with four replicates. In the present work, soil quality properties such as pH, soil organic matter, available phosphorus, total nitrogen, aluminum (Al3+), and iron (Fe2+) were measured. Additionally, the influence of organic fertilizer on the growth of blueberry (plant height, number of shoots, and leaves) was also investigated. The results indicated that both the rates of BOF (4 and 6 t ha−1 yr–1) significantly improved soil organic matter and available phosphorus. Also, BOF application greatly decreased the soil concentrations of Al3+ and Fe2+ compared to the control treatment. Similarly, 12 months after planting, the number of shoots and leaves was improved in the pots with BOF compared to that without BOF addition. From the results of this study, we recommend using BOF as the best measure for enhancing soil health and blueberry growth.

Influence of organic fertilizers and silicon on the physiology, yield, and nutraceutical quality of the strawberry crop

A suitable combination of organic sources of nutrients can allow an adequate growth, yield of the strawberry crop, and decrease the use of chemical fertilizers to the benefit of the environment and consumers. Likewise, silicon can help plants to withstand adverse environmental, biological, and edaphic conditions, increasing and improving production quality. Therefore, the objective of this study was to evaluate the effect of three sources of organic fertilization: one of animal origin (fish); one of vegetable origin (corn), and one of animal and vegetable origin (fish - corn) plus a chemical treatment such as control (Steiner), with three silicon concentrations of 0, 15 and 20 ppm. Growth parameters, physiological parameters, as well as nutraceutical performance and quality were evaluated in strawberry fruits of the Camino Real cultivar, under a completely randomized design with factorial arrangement (4 x 3). The results of vegetative growth and physiological parameters of the treatments with organic fertilization showed statistically equal values ​​to the control treatment, likewise for the yield and nutraceutical quality. The addition of silicon to the doses studied did not cause effects on any of the variables studied. The results suggest that it is totally feasible to replace chemical fertilization with organic, obtaining identical results.

Plant succession of natural grasslands under radical improvement in the southern forest-steppe of the Western Siberia

The low fodder productivity of vast areas of natural forage lands in Siberia necessitates their radical improvement. High fodder productivity will strengthen the fodder base of the region, which is important for the developing cattle breeding. The authors carried out an experiment of radical improvement of natural grasslands in order to clarify and develop methods of increasing the productivity of natural grasslands in the southern forest-steppe of Western Siberia. The authors studied the effect of two factors: The first factor - tillage followed by sowing of perennial grasses; The second factor - the effect of organic fertilizers (20 t/ha). By the second year of observations in the variant where soil disking was carried out, only motley grasses were noted. Disking followed by seeding of perennial grasses promoted the development of seeded grasses (80% of the composition of the herbage). The remaining niche of grass stand was occupied by motley grasses. The influence of organic fertilizers in the second year of observations almost does not affect the structure of herbage, only in the variant with the sowing of grasses the distribution of different botanical groups is more uniform. The composition of grass stand changes significantly between the second and sixth years of observations under the influence of tillage and organic fertilizers. The development of cereals and legumes in the herbage in the variant without tillage in the third and subsequent years is noted. By the sixth year of observations in the herbage remain only cereal grass (60%) and mixed grass (40%). Dynamics of herbage structure by years of development on the background of organic fertilizers differs little from the herbage without fertilizers. By the second year of observations, there is no significant influence of fertilizers and tillage on the yield of grasses. In the sixth year of observations (2016) there was a significant influence of organic fertilizers. Even without soil treatment, the yield almost doubled from 0.6 t/ha in the version without fertilizers to 1.1 t/ha of absolutely dry matter in fertilized variants. The greatest increase in yield was noted in the variant with discing, 2.7 times (from 0.6 to 1.6 t/ha); in the variant with grass seeding and discing 1.4 times (from 1.1 to 1.6 t/ha) (absolute dry matter). The effect of tillage on the yield without fertilizer was much less. Consequently, tillage and fertilization contribute to a more uniform distribution of representatives of different botanical groups of grasses in the herbage. The productivity of the natural meadow increases significantly by the sixth year of observations after the improvement.

Influence of Organic Fertilization on Agro-morphological Traits and Mineral Nutrient Content in Bean Grains

Plant residues such as animal feed weeds and bean straws are excellent sources of raw material for the production of organic fertilizers. In view of this, the objective of this work was to evaluate the effect of organic fertilization on the agromorphological and nutritional aspects in bean grains. The experiment was implemented in the field, in a randomized block design, with three replications, in a split plot scheme, with two types of organic compound (elephant grass enriched with cattle manure) and (bean straw enriched with cattle manure) applied in six increasing doses (0.0, 33.32, 66.65, 100.00, 133.32 and 166.65%) control treatment (recommended mineral fertilization). It was possible to identify interaction between the type of compound and the doses applied only to PL. With a yield of 2.8 t ha-1, mineral fertilization did not differ from treatment with 0.0% organic fertilizer. The dose of 166.65% organic fertilizer increased grain yield reaching 3.8 t ha-1 compared to 2.4 t ha-1 obtained in the treatment with 0.0%. In addition, this treatment increased the K content in the grains. On the other hand, the application of 133.32% of organic fertilizer can be indicated for the increase in mg content in the grains.

Recycling of biogas wastewater to organic fertilizers and influence of organic fertilizers on maize, mung bean growth and yield under the field conditions

The objective of the study was to utilize the biogas effluents to produce solid and liquid organic fertilizers, as well as evaluate their effect on the growth and yield of corn and mung beans under field conditions. For liquid organic fertilizer, biogas effluents were mixed with fish emulsion and beneficial bacteria while biogas effluents-absorbing coal slag was mixed with sugarcane filter, fishmeal and beneficial bacteria to create solid organic fertilizer. Liquid organic fertilizer was irrigated with a dose of 5 L/1000 m2 while solid organic fertilizer was applied with a dose of 1 ton/ha with 75% recommended NPK formula for maize and mung bean. The results showed that applying solid or liquid organic fertilizer formulated from biogas effluents with other amendments helped to reduce the amount of recommended NPK fertilizer by 25%, but still maintained growth and yield of maize and mungbean equivalent to the control treatment fertilized with 100% recommended NPK. In conclusion, the amount of organic matter and N, P, K in biogas effluents from biogas digesters can be utilized to produce organic fertilizers which not only help to reduce chemical fertilizers, but also solve the environmental problems and create new friendly value-added products for practicing sustainable agricultural production.

The Influence of OrganicFertilizer and Dosage of NPK Multiple Fertilizer on Growth and Yield of Cucumber (Cucumis sativus L.

The administration of organic fertilizer to provide nutrients for plants is insufficient. It is because organic fertilizers contain low nutrients. Thus, plants need more nutrients that are obtainable from the administration of inorganic fertilizers. This research aimed to find: the effects of the best types of organic fertilizers on the growth and yields of cucumbers; the effects of the dose of NPK compound fertilizers on the growth and yields of cucumber; and the effects of interaction between the various types of organic fertilizer and the dose of NOK compound fertilizers on the growth and yields of cucumber. This research used Factorial Randomized Block Design with three replications. The first factor was the Various Types of Organic Fertilizers consisting of Without Organic Fertilizers, Goat Manure, and Petrogranik Organic Fertilizers. The second factor was the dose of NPK compound fertilizers of 200, 250, and 300 kg/ha. Analysis of variance was then performed and followed by Duncan Multiple Range Test (DMRT). Research results indicated that the treatment with various types of organic fertilizers provided significant effects on all observed variables; in the treatment with the Dose of NPK compound fertilizers provided significant effects on the plant and fruit weights and did not provide significant effects on other variables; interaction of various types of organic fertilizers and the dose of NPK compound fertilizers did not provide significant effects on all observed variables; Various types of organic fertilizer, such as goat manure provided the best growth and yields; the Dose of NPK compound fertilizers of 250kg/ha provided the best growth and yields of cucumbers.

The Influence of Organic Fertilizers on the Abundance of Soil Microorganism Communities, Agrochemical Indicators, and Yield in East Lithuanian Light Soils.

Soil microorganisms are one of the main indicators used for assessing the stability of the soil ecosystem, the metabolism in the soil, and its fertility. The most important are the active soil microorganisms and the influence of the fertilizer applied to the soil on the abundance of these microorganisms. We aimed to investigate how the applied organic fertilizers affect the most active soil microorganisms, which determine the soil fertility and stability. Fungi, yeast-like fungi abundance, and abundance of three physiological groups of bacteria were analyzed: non-symbiotic diazotrophic, organotrophic, and mineral nitrogen assimilating. This study is valuable because relatively few similar studies have been performed on infertile Lithuanian soils. The first results of a long-term study were obtained. The results show the effect of fertilizers on trends in the changes of microorganism community diversity; however, more analysis is needed to assess the impact of organic fertilizers on the most active soil microorganisms. Therefore, the investigation was continued. The results of the 2020 quantitative analysis of culturable soil microorganisms show that the highest abundance of organotrophic and non-symbiotic diazotrophic bacteria were recorded during the summer season. Meanwhile, the abundance of bacteria assimilating mineral nitrogen and fungi was higher in autumn. Agrochemical parameters were determined at the beginning of the experiment. The highest concentration of Nmin in the soil was determined after fertilizing the plants with the combination of granulated poultry manure (N170) + biological substance Azotobacter spp. The yield of barley was calculated. It was found that the highest yield of spring barley in 2020 was obtained by fertilizing the experimental field with organic in combination with mineral fertilizers.
