Purpose: The present study to investigate the earthworm Eisenia fetida was a chief organism for accumulation of heavy metals (Pb, Cr, and Cd) in their body tissue from sewage sludge with different combinations of animal dung and converted into rich organic vermicompost which plays a beneficial role for environment, animals and human health. Method: Animal […]
Purpose: Although the popularity of liquid organic fertilizers (LOFs) has considerably increased recently, there have been concerns over their usage due to low nitrogen content. This study aims to discuss the current developments in nitrogen-enriched LOFs that address the above limitation, subsequently promoting sustainable agricultural practices. Method: A thorough review of existing literature on nitrogen-enriched […]
Purpose Profiting from agricultural waste and lowering production costs for farmers have been made possible by the incorporation of bagasse and local resources as a substitute for sawdust. Method The experiment was using a CRD. Follows: Bagasse 100 % Bagasse: Rice straw (25:75%) Bagasse: Rice straw (50:50%) Bagasse: Rice straw (75:25%) Bagasse: Giant mimosa (25:75%) […]
Purpose No research has been published on the effect of chemical processing on the degradability and nutritional value of cumin residue. Chemical processing, such as urea, sodium hydroxide, and hydrogen peroxide, has been widely investigated to increase the nutritional value of grain residues, but information on cumin residue is limited. The effects of untreated and […]
Purpose: Waste and waste disposal is a universal problem and attention is required in all ways. The plant generated waste (leaf litter) is also a type of organic waste that creates multiple issues in urban areas. Method: Vermicomposting is a suitable alternative safe, hygienic, and cost-effective disposal of organic solid waste with the help of […]
Purpose: Fermented cow urine (cow bio urine) is used as an organic source of nutrients. This study aimed to determine the effect of various concentrations of cow bio urine as the organic nutrient source on the growth and yield of vegetable crops in hydroponic systems. Method: Research was conducted in a greenhouse at the University […]
Purpose: This study was carried out with the aim of improving the use of compost products as compost tea and humic substances fertilizers, to study the evolution and the degree of compost maturity, and to use the chlorophyll as an indicator of compost quality. Method: The compost tea and humic substances were prepared from different […]
Purpose: This study analyzed the ability of Black Soldier Flies Larvae (BSFL) in reducing grease waste and the effect of variation in feed composition on the growth rate effect of larvae age at 8 days, 12 days, and 16 days. Method: Before reaching the specified age (8, 12, or 16 days), the larvae are fed […]
Purpose Maize (Zea mays L.) is a major crop grown and consumed in Nigeria but poor soil quality has resulted in low yield. This study assessed the quality of compost produced from agricultural wastes and its impact on the yield of Zea mays L. Method The composting process was carried out on a windrow (2 […]
