Purpose Many studies evaluate the effect of successive applications of chicken manure on soil attributes. In Brazil, the commercialization of this waste is common, implying on its sporadic use instead of many applications at the same area. The short-term effects of a single application of chicken manure and the role of its composting on soil […]
Purpose The swelling characteristics and cracking of expansive clayey soils usually lead to their low yield, and as a result, large areas of expansive soils remain uncultivated and unproductive. There is a need for the development of simple, low-cost technologies which will bring these soils into production. The amendment of expansive clayey soils with agricultural […]
Purpose The increase in demand for fish has necessitated the establishment of fish pond. The discharge of spent pond water pollutes the adjoining surroundings. The aim of this investigation was to determine the suitability of artificial pond wastewater (APWW) as source of manure for crop cultivation. Method Cowpea seeds were planted in polybags containing soil […]
Purpose An experiment was conducted to evaluate the effect of dried sweet orange (Citrus sinensis) peel (DCSP) on humoral immune response of broiler chickens. Methods Four hundred 1-day-old Ross 308 broilers were distributed according to a completely randomized design into five treatments with four replicates of 20 chicks each. The following five dietary treatments were […]
Purpose Liquid organic fertilizers produced from agricultural residues and industrial wastes are becoming increasingly popular. This study aimed to examine the effect of liquid organic fertilizers produced from waste molasses, distillery slop and sugarcane leaves on the growth of Green Cos Lettuce (Lactuca sativa var. longifolia). Methods Six formulas of liquid organic fertilizers were produced […]
Purpose The research aimed to study the effects of size reduction and composting duration of empty fruit bunches (EFB) on straw mushroom production, and to examine the doses of fertilizers commonly used among farmers. Methods The experiment was done in two stages. The first stage was for identifying the optimum physical parameters of EFB, and […]
Purpose The main objective of this study was to assess the physiochemical properties and phytotoxicity of compost made from different organic waste materials sourced from local markets. Methods The Stack pile composting was carried out with market waste, sawdust, rice straw, and swine manure in four different combinations. Parameters such as temperature, pH, nitrogen, phosphorus, […]
Purpose Vemifltration units are sludge-free, noise-free and low- or no-electricity-requiring systems of operation. The aim of this study was to emphasize wastewater treatment by vermifiltration technology using waste-eater earthworms to highlight the benefits of clean and nutritive vermifiltered water (vermiaqua) uses in agriculture to the farmers. Methods Wastewater sample was filtered through fabricated vermifiltration unit […]
Purpose Although the world’s food production is approximately 3.99 billion metric tons, one in nine people remain malnourished. In combination with the projected world population of nine billion by 2050, further malnourishment of both humans and animals may occur; therefore, understanding of the current status of food waste and reuse is important.Methods An extensive literature […]
Purpose Bio-fermentation has been routed as a viable alternative for the treatment of organic waste, which can provide renewable energy and can return nutrients to the soil with its byproducts. In this context, the objectives of the research were to analyze the benefits that a plastic plug-flow bio-digester can provide for treatment of bovine manure; […]
