Purpose Chemical decomposition was studied as a potential method for the rapid conversion of waste to organic fertilizer. Methods Chemicals were screened, and process parameters were optimized. The physicochemical properties, phytotoxicity, and manurial efficiency of the product were assessed. A prototype machine was fabricated for the operation. Results Chemical treatment of ground fresh waste with […]
Purpose Effect of various combinations of potting substrates was assessed to enhance vegetative growth, plant productivity and mineral composition of Caladium bicolor. Methods Different substrates like leaf compost, farmyard manure, coconut compost, compost and perlite were used in different combinations with silt. Bulbs were sown in pots filled with different combinations of potting substrates, which […]
Purpose Faecal sludge (FS) has been co-composted with many organic solid wastes globally. Agricultural wastes, such as oil palm empty fruit bunches (EFB) and cocoa pod husks (CPH), have received very little research attention as far as combining with FS is concerned. This study aimed at co-composting these wastes at different ratios to produce safe […]
Purpose The investigation of the phytoextraction potential of three vegetable plants grown in soils amended with decanter cake. Method Pot experiments were conducted to investigate the response of decanter cake composition on the phytoextraction of metals (Mg, Zn, Ni and Cu) by lady’s finger, tomato and brinjal plants. The phytoextraction properties of these plants were […]
Purpose Declining water resources, increasing drought period and increasing irrigated area cause a shift to deficit irrigated production which is not based on full water requirement. This study was conducted to investigate the impacts of two different deficit irrigation methods, including traditional deficit irrigation (TDI) and partial root-zone drying (PRD) on water use efficiency (WUE) […]
Purpose Microbial pathogens can lead to health problems and disease transmission. Present study aimed to evaluate the microbial quality and quantity of vermicompost production and to compare to the current Iranian standards to protect public health and environmental concerns. Method This is a pilot-scale experimental study conducted in the Public Health laboratory of Shahid Sadoughi […]
Purpose A field study was conducted at Dire Dawa, Eastern Ethiopia, with an objective to find out an optimum combination of inorganic (NP) fertilizer and excreta-based vermicompost for best economic yield and quality of tomato and to assess their effect on selected physicochemical properties of amended soil after crop harvest. Methods The experiment consisted of […]
Purpose Wastes were composted and applied as the soils amendment to improve soil fertility and crop productivity. The study aimed at assessing the nutrient uptake and growth of spinach (Spinacia oleracea L.) grown in soils amended with cow manure after a co-composting process. Methods Sandy loam and silt loam soils were amended with cow manure […]
Purpose Flower waste dumping in landfills and other disposal sites is causing major environmental issues due to its highly biodegradable nature. Instead, flower waste can be successfully composted for its higher nutrient value. Therefore, this study evaluated the pile composting of flower waste with different combinations of cow dung and saw dust to produce stabilized […]
