Purpose The chicken droppings can have a negative impact on the environment and public health. In this work, we are interested in treating this waste by anaerobic digestion and we estimate the national potential of green energy produced by anaerobic digestion and map the areas that need digesters to improve national poultry farming. Methods The […]
Purpose Effective vermicomposting of Salvinia natans is a good alternative for protecting wetlands damaged by the weed due to the vast potential for use of the product vermicompost in agriculture, but the presence of toxic metals in the weeds may deter the usage. Methods Research was carried out on the physico-chemical and biological characteristics as […]
Purpose An experiment was conducted to assess the ability of municipal solid waste compost (MSWC), peat, perlite and vermicompost (VC) to improve the growth of tomato (Lycopersicon esculentum L.), an important horticultural commodity, in hydroponic culture. Methods Organic matter, when used as a substrate, can affect tomato cultivar ‘Grandella’ plant growth. In this study, we […]
Purpose In waters and wastes, direct pathogen detection is difficult and time consuming. Therefore, coliforms are used as indicators to measure the presence of pathogens. Composts originated from extrements, sewage sludges and plant wastes those contact with manures may have potential health hazard to human. Therefore, the detection of coliforms both during composting and in […]
impact of vermicompost leachate (VCL) and inorganic fertilizer either alone or in combination on growth and biochemical parameters in Stevia rebaudiana (Bertoni) through a soilless culture system. Methods The cattle manure-based vermicompost was processed by earthworms and the resulting leachate was brewed for 48 h and then collected in the system reservoir for use in […]
Purpose Field experiment was conducted to investigate the effect of enriched pressmud compost prepared from sugarcane industries byproducts on soil nutrient availability, growth, yield parameters and yield of rice. Method The effect of five levels of pressmud compost, viz., 0.00, 1.25, 2.50, 3.75 and 5.00 t ha-1 in two varieties, viz., ADT 36 and ADT […]
Purpose Agro-industrial wastes are posing serious challenges for the agro-industries. Composting and co-composting of such wastes will lead to converting such wastes into a useful product that will serve as a soil conditioner. The present research investigated the kinetics of composting and co-composting of several agro-industrial wastes. Methods Seven pilot scale composting and co-composting piles […]
Purpose The purpose of this study is to investigate the composting performance of anaerobically treated palm oil mill effluent (AnPOME) mixed with paper and grass clippings. Methods Composting was conducted using a laboratory scale system for 40 days. Several parameters were determined: temperature, mass reduction, pH, electrical conductivity, colour, zeta potential, phytotoxicity and final compost […]
Purpose Since simultaneous use of organic and mineral fertilizers on the basis of their chemical compositions can lead to better plant growth and soil fertility, the roles of municipal waste compost (MWC) and nitrogen (N) fertilizer on growth and mineral composition of tomato and some soil properties were evaluated under greenhouse condition. Methods Treatments involved […]
Purpose The present work reports an economically attractive improvement in the area of producing particulate slow release nitrogen fertilizer using lignin as a waste effluent of pulp and paper manufacturing process. Methods An improved coating of modified lignin was applied on the surfaces of the individual urea particles. The Kraft and Sulfite black liquors obtained […]
