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 The study assessed trace metal levels in the leaves, stalks and roots of Spinacia oleracea harvested from soil treated with urine in comparison to chemical fertilizers and biosolids. Methods Spinacia oleracea seedlings were planted on soils pretreated with urine, chemical fertilizers and biosolids. Results The soil treated with chemical fertilizers resulted in an increase […]
Purpose A pilot composting project was initiated as part of a 200 tons/day solid waste recycling plant with active involvement of several local stakeholders. The project aimed at introducing compost production and use in the village of Al Jalameh, Palestine. This paper describes the successes and lessons from the pilot project. Methods Based on the […]
Purpose Solid waste management has become a serious global problem. There is a strong need to recycle them as these wastes are rich in plant nutrients and soil conditioners. The different organic wastes can be efficiently degraded into nutrient-rich vermicompost by using earthworms. In this review, an attempt has been made to highlight the vermicomposting […]
Purpose The overharvesting of the endemic palm tree Euterpe edulis Mart. (Arecaceae) from the Brazilian Atlantic Forest hotspot and the destination given to the sludge produced from urban sewage treatment are both serious environmental issues caused by human activities. In order to find solutions or alternatives for both the issues, we aimed to investigate the […]
Purpose To comply with purposes of circular economy and sustainability, as well as promoting an appropriate destination for waste from Bactris gasipaes agro-industry and adding value to this product, we evaluated the compost of the plant residue as substrate for seedlings production. Methods Waste was collected, composted, dried and ground. Compost samples were characterized chemically […]
Purpose Compost production technology and use are known among Ghanaians farmers. However, the long composting period averaging three months has had adverse effect on adoption. The black soldier fly (Hermetia illucens) larvae (BSFL) feed voraciously and breaks down organic wastes fast. Addition of rice husk biochar (RHB) neutralises acidity and aerates the compost. Combined application […]
Purpose This paper investigates the composting recovery of different bio-wastes and the use of the composts produced as soil fertilizer and organic amendment. Method A composting process was carried out for 111 days using different organic wastes (fruits, vegetables, olive pomace, poultry, and cattle manure). The physicochemical properties of the generated compost were determined. The […]
Purpose Organic residues of coffee pulp, sugarcane bagasse and mature bovine manure are a source of organic matter and nutrients for the multiplication of endomycorrhizae consortia. Therefore, the purpose of this research is to multiply the AMFs in such substrates to decrease soil and water pollution. Method A pot experiment under greenhouse conditions was conducted […]
Purpose The objective of this study was to evaluate soybean production and nutrient availability in the soil using doses of organic fertilizer formed from chicken carcasses, compared to the use of mineral fertilizer. Method The evaluated treatments, produced from chicken carcasses, were calculated to provide 0, 30, 60, 90, 120 kg ha-1 of P2O5, that […]
