<p><em><strong>Counseling of Soil Fertility, Organic Fertilizers, Pests and Plant Diseases for Baranuri Farmers Group</strong>. </em>The Baranuri Farmers Group (KT. Baranuri) is one of the providers of vegetables for the people of Ende City. The results of interviews with farmers obtained several problems, namely, there is no data on soil fertility and lack of understanding of soil fertility, organic fertilizers, pests and plant diseases. The solution given is to analyze soil pH and organic-C to be used as a reference for soil fertility conditions as well as counseling about soil fertility, organic fertilizers, pests and plant diseases. This service activity aims to provide information on soil fertility, increase farmers' knowledge regarding soil fertility, organic fertilizers and plant pests and diseases. The counseling method used is a group approach. Purposive soil sampling, samples were taken diagonally. The organic-C content was analyzed in the laboratory by Walkley and Black method, while soil pH was measured directly on the field using 4 in 1 Soil Survey Instrument and then matching with the criteria of assessment of soil analysis results by the Indonesian Soil Research Institute. The results obtained were the soil pH was 4-5 (very acidic-acidic) and soil organic C was 2.03-2.37% (moderate). The extension activities were succeeded in increasing public knowledge from 46.7% to 86.7% (an increase of 85.7%). The recommendation from this activity is to create a demonstration field to apply an organic fertilizer that can be observed directly by farmer groups.</p>

With the continuing 20% growth rate in the organic industry, organic vegetable crop production has increased to 98,525 acres in the United States. The requirement for certified organic vegetable producers to implement a soil-building plan has led to the development of soil fertility systems based on combinations of organic fertilizers and cover crops. To determine optimal soil fertility combinations, conventional and organic bell pepper (Capsicum annuum) production was evaluated from 2001 to 2003 in Iowa, comparing combinations of two synthetic fertilizers and three compost-based organic fertilizers, and a cover crop treatment of hairy vetch (Vicia villosa) and rye (Secale cereale) in a strip-tilled or fully incorporated cover crop system. Organic pepper growth and yields equaled or surpassed conventional production when nitrogen (N) was provided at 56 or 112 kg·ha−1 from compost-based organic fertilizer. Soil analysis revealed higher N in plots where cover crops were tilled compared with strip-tilled plots, leading to recommendations for sidedressing N in strip-tilled organic pepper production. Increased incidence of disease was also detected in strip-tilled plots. Postharvest weight loss after 6 weeks in storage was similar in organic and conventional peppers. The addition of calcium and sulfur products in conventional or organic fertilizer regimes did not increase pepper production or postharvest storage potential. Despite application challenges, cover crops will remain as critical components of the organic farm plan for their soil-building benefits, but supplementation with approved N sources may be required for optimal pepper production. Organic growers should conduct their own tests of organic-compliant soil amendments to determine cost effectiveness and value for their site before large-scale application.

Sustainable agricultural development depends mainly on the recycling of organic wastes to reduce environmental pollution, as well as to reduce the use of mineral fertilizers. Expired milk products are rich in organic carbon and nitrogen, so they are good raw materials for making organic fertilizers. In this study, expired milk products were converted to organic fertilizer (EDPF) by gravity and thermal treatments. The extracted EDPF was used in the nutrition of Williams banana plants under field conditions for two growing seasons. The field experiment consisted of four treatments including: C = control without N fertilization, U = traditional urea, SRU = slow-release urea, and EDPF. EDPF significantly (p < 0.05) improved the growth and yield of Williams banana in comparison to U and SRU. EDPF significantly minimized the soil pH and increased the soil organic-C and cation exchange capacity compared to the other treatments. EDPF increased the total yield of bunches by 20% and 17% in the first and second years, respectively, above U and SRU. EDPF surpassed the traditional and slow-release urea in its ability to supply the banana plants with nitrogen. NH3-N loss from U, SRU, and EDPF reached 172, 132, and 100 kg N ha−1, respectively, which accounted for 34%, 26%, and 20% of the total added nitrogen. Nitrogen loss from the investigated treatments was in the order: U > SRU > EDPF > C. EDPF significantly reduced the ammonia volatilization compared to U and SRU by reducing the soil pH and increasing the soil organic matter. The dynamic of NH3 emissions not only depends on the nitrogen form but also on climatic conditions and concentrations of NH4+ in the soil solution. Protecting the ecosystem and maximizing the benefits of wastes utilization can be done through the recycling of expired dairy products to organic fertilizers.

Rabbit Manure

University of Islam Malang has a sister village program in Codo Village, Wajak District, Malang Regency which is recognized as a high agricultural and animal husbandry potential. In recent years, farmers in Codo village have developed rabbit farms. Further, they had a rabbit breeder group. However, the increasing number of rabbit breeders raises new problems, namely the abundance of rabbit dung. Proper strategy is needed to solve the problem. This encourages UIM to conduct a community service program on technology transfer regarding making solid and liquid organic fertilizers from rabbit dung in Codo Village. The activity focused on three tasks. First, the counseling and training for making solid and liquid compost. Second, the counseling about the importance of using organic fertilizers for soil fertility. Lastly, the discussions on various soil fertility issues related to agricultural land. This community service activity was initiated in August–November 2019 and successfully carried out with the help of students as facilitators. The use of rabbit dung as a solid and liquid organic fertilizer provided additional knowledge for rabbit breeders. They got information about the quality of rabbit manure compost and its impact on agricultural land. As a result of this activity, 83% of the community has been able to make organic fertilizer based on rabbit dung and produce solid and liquid organic fertilizer products with different chemical compositions.

Fertilization is an action in plant care. Fertilization provides additional nutrients for the soil. Fertilization has a large influence on plant growth and production. Fertilization consists of organic and inorganic fertilizers. Both of these fertilizers must be balanced so that the nutrient content can be maintained properly. The use of fertilizers an organic fertilizer that is widely used, but the use of chemical fertilizers on an ongoing basis will reduce the level of soil fertility. This must be balanced with organic fertilizer. One of the organic fertilizer is guano fertilizer. This fertilizer is fertilizer made from animal waste, namely bats. This fertilizer has a very good content including nitrogen, phosphorus, and potassium. Knowledgethis fertilizer will still be low, so that an introduction and practice about guano fertilizer is needed. Therefore a community service activity was carried out on the development of the manufacture of guano fertilizer. Guano fertilizer development is carried out in the form of granules (granules). The targets of this service are vocational students who are related to agriculture. Vocational students are selected as the young generation to know about organic fertilizers and are able to contribute to the implementation of the agricultural industry. Community service activities were carried out with a presentation of the theory and practice of making guano fertilizer. As a result of this activity, students learned about organic fertilizer, namely guano fertilizer and its contents, nutrient content in the soil, balance in maintaining nutrient content in the soil, the practice of making guano fertilizer, and the creation of granule form from guano fertilizer.

Abstract Background Plant diseases caused by fungal pathogen result in a substantial economic impact on the global food and fruit industry. Application of organic fertilizers supplemented with biocontrol microorganisms (i.e. bioorganic fertilizers) has been shown to improve resistance against plant pathogens at least in part due to impacts on the structure and function of the resident soil microbiome. However, it remains unclear whether such improvements are driven by the specific action of microbial inoculants, microbial populations naturally resident to the organic fertilizer or the physical-chemical properties of the compost substrate. The aim of this study was to seek the ecological mechanisms involved in the disease suppressive activity of bio-organic fertilizers. Results To disentangle the mechanism of bio-organic fertilizer action, we conducted an experiment tracking Fusarium wilt disease of banana and changes in soil microbial communities over three growth seasons in response to the following four treatments: bio-organic fertilizer (containing Bacillus amyloliquefaciens W19), organic fertilizer, sterilized organic fertilizer and sterilized organic fertilizer supplemented with B. amyloliquefaciens W19. We found that sterilized bioorganic fertilizer to which Bacillus was re-inoculated provided a similar degree of disease suppression as the non-sterilized bioorganic fertilizer across cropping seasons. We further observed that disease suppression in these treatments is linked to impacts on the resident soil microbial communities, specifically by leading to increases in specific Pseudomonas spp.. Observed correlations between Bacillus amendment and indigenous Pseudomonas spp. that might underlie pathogen suppression were further studied in laboratory and pot experiments. These studies revealed that specific bacterial taxa synergistically increase biofilm formation and likely acted as a plant-beneficial consortium against the pathogen. Conclusion Together we demonstrate that the action of bioorganic fertilizer is a product of the biocontrol inoculum within the organic amendment and its impact on the resident soil microbiome. This knowledge should help in the design of more efficient biofertilizers designed to promote soil function.

Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in four representative communities during the 2006-09 growing seasons to identify an integrated soil management strategy that may help to improve soil fertility and productivity by increasing soil organic matter. Soil samples collected from fields of different lengths of cropping (LC) and fallow (LF) showed that LC decreased and LF increased total (TOC) and active soil organic C (AOC), and total (TN), inorganic (TIN) and active soil N (AIN). Field trials established with combinations of soil inorganic fertilizers (SIF) and local and alternative soil organic fertilizers (i.e., cow and sheep manure, household compost and a biofertilizer) revealed that the cow and sheep manure combined with SIF significantly affected soil properties, such as pH, soil test P, TN, TIN and TOC, soil water content and bulk density and significantly increased the production of potato (Solanum tuberosum L.) and a subsequent quinoa (Chenopodium quinoa Willd.) crop. Results of testing a portable field method to assess N status of potato plant tissue suggest that use of the Cardy nitrate-N meter may have some promise for tissue testing for potato in the Andean highlands of Bolivia, where access to soil and plant tissue testing services is limited.
