“…Organic waste disposal is a major problem and the conversion of this material into organic fertilizer is a desirable option vis à vis the severe depletion of soil organic matter and declining crop productivity (Lal, 2015;Sudharmaidevi et al, 2017). It is known that fertilizers from organic waste have a positive effect on food quality, and that many suitable types ofwaste can be used to produce it, as shown in the figure below.…”

The perception and utilization of organic manure have all along been critical, due to the socioeconomic and demographic factors among farmers of different parts of the world including India. A study aimed to explore factors affecting farmer’s perception about organic manure production and its utilization in Dakshina Kannada. A questionnaire-based survey was used to collect data from farmers and bears quantitative data. This data shows that the 3.2% of farmers adopted farming activities for more than 30 years, and the experience acquired has influenced the knowledge and perceptions on utilization of organic manure. It was found that 86% of males and females positively enjoyed producing organic manure, while 14% had a negative attitude towards the practice. The core factor influencing farmers to produce organic manure from municipal solid wastes was high yield/crop production which accounted for 16.1% of all respondents. The study indicates that the attitude and willingness to use organic manure from organic waste were high among the farmers of Dakshina Kannada, India. Therefore, an approach that can get the farmers involved in organic manure production using organic wastes could be implemented to inform good practices.

“…They are inevitable for the natural resource management in the farmers' fields. Controlled composting guided by microbial interventions dependent on defined microbiological processes to decompose agricultural residues properly and timely and produce high-value low-cost bioorganic farm inputs (Ahmad et al 2007;Singh and Nain 2015;Singh and Prabha 2017;Sudharmaidevi et al 2017). This is how rapid composting processes can help farmers in timely production of compost and fortified bioorganic farm inputs of desired quality for organic farming needs and high-value commercial crops like vegetables, fruits, flowers, and organic crops (Hoornweg et al 2000;Seyedbagheri 2010).…”

Purpose Agricultural chemicals either used as nutrient inputs for soil fertility or pesticides are creating physicochemical and biological deterioration of the soils and disturbing the agro-ecosystems worldwide. Alarming concerns towards integrated agroecology demand for renewed interest in low-external input-based farming practices. These practices comprise strengthening of soil biological properties, recycling of inherent soil minerals and reuse of agricultural residual wastes. Methods We described approaches for the bioconversion of agricultural residual wastes into value-added compost. The process involves conversion of residual waste into raw compost followed by its fortification with beneficial decomposer microorganisms to produce quality fortified compost product. Finally, incubation of fortified compost with single or consortia of beneficial microorganisms like N-fixers, P-solubilizers or K-mobilizers and biocontrol agents further enriches compost to produce bioorganic products.

“…This process will lead to sustainable and balanced production of organic fertilizer for soil applications, which will increase yields and improve soil health and environmental quality. The method can be a model of waste processing that can be replicated, especially for developing countries (Sudharmaidevi et al 2017).…”

Purpose This study aimed to design a biogas digester that works thermophilically and mesophilically and tested its performance to produce biogas and digestate. Methods This study used some experimental methods, which consists of: (1) design and construction process of the digester which can facilitate the thermophilic process as a pretreatment of the feedstock and the anaerobic digestion process of the substrate; (2) determination of the quantity of biogas, liquid digestate, and compost; and (3) testing digestate quality as a liquid organic fertilizer for Ipomoea reptans. Results The built biogas digester was able to accommodate thermophilic digestion that runs intensely in the pretreatment tank, where the complex organic compounds, namely cellulose and hemicellulose, decomposed intensively, so that it becomes a suitable substrate. As raw material, every 4 kg of banana waste, can produce biogas, digestate and dry compost of 10,200 cm 3 (highest yield), 5900 mL, and 1420 g, respectively. The highest Ipomoea reptans growth was achieved by digestate treatment from banana waste. Conclusions Thermophilic pretreatment could shorten the processing time to 3 days. Digestate treatment as a liquid organic fertilizer is able to provide a better supply of nutrients for plants.
