“…Composting is a good strategy towards improved and sustainable agricultural productivity (Sarkar and Chourasia 2017). Composting ensures reclamation of nutrients within plant biomass to improve soil fertility and enhance crop productivity (Chandra et al 2009).…”

“…Although the practice of composting is well known, farmers, especially in developing countries do not make the best use of the recycling opportunities available to them (Gajalakshmi and Abbasi 2008). This is mainly due to various hindrances in the composting process which among others include the long time span required for the compost to mature (Sarkar and Chourasia 2017). Waste materials of plant origin including rice straw are recalcitrant due to their lignocellulolytic structure which have practical implications in biodegradation (Anwar et al 2015;Van Soest 2006).…”

Purpose Traditional methods of composting are limited in timely production of good-quality compost due to recalcitrant nature of materials of plant origin. This study focused on evaluating the use chicken and donkey manure as starter cultures to biostimulate bioconversion of rice straw into bioorganic fertilizer. Use of starter cultures would enhance composting as a strategy for rice straw management to enhance soil fertilization and reduce environmental pollution. Methods In this study, chicken manure and donkey manure were used as starter cultures to enhance bioconversion of recalcitrant and abundant rice straw in Mwea, the main rice-producing area in Kenya. Treatments of the study included rice straw co-composted with chicken manure (T1), rice straw co-composted with donkey manure (T2) and a control (T0) consisting of untreated rice straw. Temperature, pH and electrical conductivity (EC) were monitored throughout the composting period. Resultant compost types were characterized in respect to their macro-nutrient concentrations, cation exchange capacity, pH and heavy metal content. Results Levels of temperature, pH and EC among the treatments of the study revealed significant differences at 5% level of confidence using Tukey's test. The three resultant compost types obtained were also physicochemically different as revealed by analysis of variance of cation exchange capacity, phosphorus, nitrogen and carbon content. Conclusion Results indicated that use of chicken and donkey manure significantly improved the composting process and the quality of resultant compost.

“…Cherif et al (2009) and Gwenzi et al (2015) assessed the effectiveness of MSW application on agricultural soil in northern Africa arid climate and recommended using MSW compost at a rate of 40 Mg/ha to fertilize wheat crops. Many researchers (e.g., Abbasi and Gajalakshmi 2015;Bhat et al 2017;Sarkar and Chourasia 2017;Chaturvedi and Verma 2015) suggested adding different kinds of bacteria to improve the speed and quality of composting processes. Abbasi and Gajalakshmi (2015), for example, used termites to decompose substances which resist composting, vermin composting, or anaerobic digestion such as cotton waste, coconut shells, and torn jute bags.…”

Municipal solid waste management (MSWM) is one of the major environmental issues in Tunisian cities. Rapid growth in urbanization and population rates and the changes in people's lifestyle have prompted a dramatic increase quantity and a significant shift in the composition of municipal solid waste. There is insufficient data concerning the quantities and the composition of waste streams along with the absence of a comprehensive complete overview and a wider perspective of MSWM potential that provides detailed information at region and city level. As a result, it is still impossible for the scientific community and the authorities to provide synergetic schemes to tie the problems of MSWM with how to integrate economically feasible and environmentally sustainable practices holistically. In the present study, an attempt has been made to provide a comprehensive overview of MSW, through a qualitative (compositional) and quantitative (parametric) characterization of the generated total waste generated in Tunisian cities. A 1-year research survey was conducted in seven regions in Tunisia (Great Tunis, Northeast, Northwest, Midwest, Mideast, Southwest, and Southeast) that cover the 24 provinces of the country. Collected samples revealed that the distribution of waste by region was defined by the region's demographic, economic, and industrial status. Approaches of possibly more efficient procedures that can be undertaken to improve MSW collection are discussed. At a final stage and based on the potential of biogas calculated in the seven regions, we suggest that the scientific community and the authorities should introduce applicable schemes to valorize MSW through generating biogas as a renewable energy.

“…Fortification of raw compost with plant growth-promoting bacteria and biocontrol agents like Trichoderma harzianum potentially enhance suppressiveness of soil-borne diseases and efficacy of compost microbiota against pathogenic diseases (Pugliese et al 2011;Ros et al 2017). Mushroom production is of high economic significance in many parts of the world (Marshall and Nair 2009;Zhang et al 2014) and compost fortified with beneficial microorganisms also has potentials of enterprising (Awad and Khaled 2012;Sarkar and Chourasia 2017).…”

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.
