Purpose During the apple processing procedures, a large amount of apple pomace is generated which is contains peel, core, seed, calyx, stem, and soft issue. The polyphenolic compounds in apple pomace are strong antioxidants that are able to counterbalance the free radicals; also, it is a rich source of many nutrients such as carbohydrates, minerals, […]
Purpose Present work aims at studying the influence of active (using external aerator) and passive (natural) aeration on composting of household biodegradable wastes. Methods To study the suitability of these reactors to household conditions, continuous loading was carried out for a period of 60 days. Both the reactors were loaded with cooked as well as […]
Purpose Mulching is a practice recommended for soil moisture conservation in potato. The wheat straw and rice straw obtained as major crop residues were used as mulching materials to compare their effectiveness for soil moisture retention in potato crop. Methods The field experiments were conducted in a randomized complete block design replicated thrice with three […]
Purpose The effect of different initial carbon to nitrogen (C/N) ratios on the prevalence of Salmonella spp., fecal coliforms and helminth eggs over composts produced from several mixtures of maize straw (S) and dairy manure (M) was investigated. Method Four C/N ratios (21, 22, 27, and 38) were evaluated, including one with manure only (C/N […]
Purpose An 8-week incubation study was conducted to monitor soil inorganic nitrogen (N), dissolved organic carbon (DOC), greenhouse gases (GHG) [CO2, N2O and CH4] and cumulative global warming potential (GWP) in dryland soil. Method Soil was amended with variable rates of compost (zero, 15, 30 and 45 dry Mg ha−1) and soil moistures [5% (dry), […]
Purpose Municipal sewage sludge generated from three operational wastewater treatment plants, located in the Bekaa valley of Lebanon, was assessed for its potential use as agricultural soil amendment. Method Sludge samples were taken from three treatment plants located in the villages of Iaat, Ablah and Joub Jannine during the summer season of 2018, from June […]
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. […]
