Purpose: Some literature on feeding kitchen food waste (KFW) to domestic animals is available. However, the quantification of such consumption by those animals is limited. This study attempts to investigate how various domestic animals contribute to disposing of the KFW by feeding in rural and semi-urban areas of the eastern province of Sri Lanka. Method: […]
Purpose: This study was conducted to evaluate whether vermicompost production from various plant residuals could improve the biomass and essential oil properties of Zarrin-giah (Dracocephalum kotschyi Boiss.). Method: In this experiment, different types of vermicompost were prepared from five residual biomasses of chamomile, madder, licorice, valerian, and pistachio with cow dung and Eisenia fetida worms. […]
Purpose: To understand the effect of organic wastes as fertilizer and weed management on the growth and fruit yield of tomatoes to recommend the best organic waste fertilizer and weed management practices for the production of this crop in a derived savannah agro-ecology zone of Nigeria. Method: The experiment was conducted in Nsukka, Nigeria where […]
Purpose: Fermentation process could be a low-cost strategy to stabilize and transform liquid organic residues into organic fertilizers for agricultural use. However, low nitrogen (N), phosphorus (P) and potassium (K) levels have hampered its potential use as an organic fertilizer. So, this study investigated the behavior of P, K and organic acids in the fermentation […]
Purpose: This study investigated the physicochemical properties of vermicompost from spent coffee grounds (SCG) and assessed its environmental performance using Life Cycle Assessment (LCA). Additionally, the environmental performance of vermicompost was compared to other waste treatment and utilization scenarios. Method: Two treatments of compost and vermicompost were produced from SCG and solid cow manure (SCM) […]
Purpose: GIDI organic fertilizer or water hyacinth is an aquatic plant, an excellent depollutant, and is helpful for food production as compost and regeneration of degraded soil. Maintaining its fertility and maintaining the ecological balance of the environment. The study aimed to evaluate the influence of different rates of GIDI organic fertilizer on the yield […]
Purpose: Composting process can be accelerated by seeding microbial consortium into compost of plant residues and livestock manure mixture. The consortium could also be sourced from decomposing sawdust due to extensive microbial activity. This study investigated the effect of decomposing sawdust as an inoculant on the microbial and physicochemical properties of sawdust-chicken manure compost. Method: […]
Purpose: Poultry dropping and rice-mill wastes are generated in large quantities on daily basis in Ishiagu, Ebonyi State, Nigeria. These bio-wastes can improve soil quality and pepper production. Hence, this study seeks to evaluate the effects of amendments on soil physico-chemical properties and yield of pepper varieties. Method: This experiment was carried out in the […]
Propose: In this study, vermicomposted corn waste was applied to the organic cultivation of cherry tomato seedlings under the edaphoclimatic conditions of the Brazilian semiarid region, and the effects were evaluated in the soil‒plant system. Method: The vermicomposts were prepared by mixing corn waste in an organic substrate. The experiment was divided into two parts: […]
Purpose: The quality of compost is a significant concern worldwide. This study aims to improve vermicompost quality through the utilization of enriched materials. Method: This research aimed to evaluate the impact of bonemeal and eggshell powder treatments on the quality of vermicompost derived from three waste varieties: cooked tea waste, vegetable waste, and mixed food […]
Purpose: Organomineral fertilizers (OMFs) are agronomic inputs combining organic material with mineral fertilizers. The study evaluates the biomass production and P accumulation in maize by applying phosphate OMFs from different organic sources. Method: Two soils with high (Arenosol) and low (Planosol) P content were used. For each soil, an experiment with a factorial arrangement (4 […]
Purpose: The study investigated how selected tomato genotypes performed with combined applications of cocoa pod (CP) + poultry manure (PM), kola nut pod (KP) + poultry manure (PM), and NPK fertilizer, focusing on fruit yield, mineral content, and vitamin composition. Method: The trial was carried out at Landmark University Teaching and Research Farm, Omuaran, Nigeria […]
