Purpose: Sludge treatment and reuse as a fertilizer is of great significance in Gaza Strip. This study aimed to treat sludge generated at North Gaza WWTP, to produce rich nutrients fertilizer, to apply it in a greenhouse, and to compare its performance with different fertilizers. Method: The concept of drying beds was applied to 1500 […]
Purpose Membrane filtration is recently applied to recover nutrients and dischargeable water from anaerobic sludge. The purpose of this study is to quantify nutrient separation, membrane performance, and process stability and to increase the economical applicability of the process by energetic optimization. Methods At the site of a 2.5 MWe agricultural biogas plant, a membrane […]
Purpose In Bangladesh, the sludge of textile effluent treatment plant has been considered as a potential environmental threat due to its huge volume and chemical content. Thus, the present study was carried out to assess the reuse possibility/potentiality of textile sludge in agricultural applications. Method Textile sludge was applied at different loading ratios (0–100 % […]
impact of vermicompost leachate (VCL) and inorganic fertilizer either alone or in combination on growth and biochemical parameters in Stevia rebaudiana (Bertoni) through a soilless culture system. Methods The cattle manure-based vermicompost was processed by earthworms and the resulting leachate was brewed for 48 h and then collected in the system reservoir for use in […]
Purpose The main purposes of the study were to assess the NPK fertilizer value of biogas digestates in diferent soils and to evaluate the risk of unwanted nutrient leaching. Methods The fertilizer value of digestates from anaerobic digesters was investigated in a greenhouse pot experiment with wheat in three diferent soils; silt, loam and sand. […]
Purpose This study was conducted to determine the efect of compost supplemented with jatropha cake on maize (Zea mays L) yield in a degraded soil and their residual efects on soil fertility in Ilorin, Nigeria. Methods Field trials were conducted at Kwara State University Teaching and Research Farm, Malete, in 2016/2017 cropping season. The treatments […]
Purpose Urban organic solid waste (UOSW) has great potential to be transformed into solid and liquid organic fertilizers, thus avoiding its accumulation in landfills and reducing the environmental impact caused by the generation of gases and leachates. Therefore, the purpose of this research was to study the management of the UOSW in the municipality of […]
Purpose The solubility of silica is a key parameter affecting its suitability as a rice fertilizer. Therefore, this study determined the effect of calcination temperature and duration on the physical composition of silica derived from rice husk ash. Method Rice husks were calcined at 100–900 °C for 15–120 min in an electric furnace. The solubility […]
Purpose Chicken feather protein hydrolysate (CFPH) has drawn a significant attention as a component/type of biofertilizer in recent years, because of the beneficial impact on the growth of the plant. The current study aims to evaluate the potential influence of the combination of CFPH with vermicompost (VC) on growth-promotion and yield improvement in tomato plants. […]
Purpose This study aims to evaluate the potential negative effects of rice husk as a source of fertilizer on plant growth. Method Growth tests were conducted on komatsuna (Brassica rapa var. perviridis) using three types of experiment. A pot experiment was conducted to compare different fertilizers on an individual basis. A second pot experiment was conducted […]
