Purpose Green waste (GW) composting is of increasing importance to the waste management industry in addition being a useful agricultural product that is rich in nutrient and organic matter (OM). The combination of aerated static windrow with GORE(R) cover membrane and an air-floor aeration system is a relatively new industrial-scale composting technology that has not […]
Purpose Intensification of rice cultivation to meet the growing demand has imbalanced the nitrogen level in soil. Amendments of inorganic fertilizers increase yield, but at the same time affects the environment. Hence, different amendments are to be investigated which acting sustainably on soil and the environment upholds yield gains. Method A study was carried out on acidic […]
Purpose A suitable strategy for bioconversion of agricultural waste into quality organic manure and its efficient utilization was assessed in the hilly ecosystem of Northeast India. Method Pits were dug in terrace lands and filled with chopped plant biomass (rice straw, maize stover and mixed weed biomass) with alternate layers of cow dung at 3:2 […]
Purpose Rice straw is a waste product from the harvesting of Oryza sativa L. It is recurrently burned resulting in producing overheating, soil degradation, and air and water pollution. Method A pot experiment was designed under polyhouse conditions to evaluate the effects of rice straw as a substrate with Sorghum bicolor (L.) Moench, Hordeum vulgare L. […]
Purpose A study was conducted to extract calcium chloride from eggshell and also to check the effect of commercially available and extracted calcium chloride on quality characteristics of fresh-cut fruits. Method Eggshells were mixed with a hydrochloric acid solution and stirred occasionally until no gas bubbles were observed (3 h). The mixture was centrifuged at […]
Purpose This research aimed to produce biochar from coffee residues (CR) as well as to develop the guidelines for using it as a fuel and a soil amendment. Method Initial properties of coffee residues have been characterized before experimenting with a biomass kiln, designed for use in biochar production. By carbonization method, using biomass kiln […]
Purpose The objectives of this study were to assess the black soldier fly larvae (BSFL) composting potential and to analyze the quality of organic fertilizer produced for agricultural purposes. Method The waste biodegradation was determined by varying waste feed treatment (2, 2.5, 3.0, 3.5, to 4 kg) and control treatment of (2 kg) of heterogeneous […]
Purpose Adoption of co-composting to treat swine slurry can reduce risks of pollution and produce organic fertilizer. Wood shavings and sawdust are the usual bulking agents used in such treatments, however planted forest is a feedstock source of slow renewability rate. Thus, the prospection of alternative biomass feedstock in regions of high animal density, may […]
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 […]
Purpose This research work described the effect of organic waste (poultry manure) on soil cumulative infiltration rate (CIR), soil organic matter (SOM), and maize performance on two contrasting alfisols of southwestern Nigeria. Method Six treatments of poultry manure were applied in split at 0 Mg/ha, 2 Mg/ha, 4 Mg/ha, 6 Mg/ha, 8 Mg/ha, and 10 Mg/ha, in replicate under a completely […]
