Purpose Huge amount of yard waste is produced in cities with excessive agricultural activities like Cameron Highlands, Malaysia where most of the time the yard waste is being managed poorly and big portion of it ends in dump sites. Therefore, this study aims to evaluate the applicability of converting yard waste generated in Cameron Highlands […]
Purpose Composting has the potential to recycle wastes as a means of conserving natural resources. The study was aimed at examining feasibility of producing nutrient-enriched composts from pest infested cocoa pods with chemical amendments and using manure composts as a fertilizing material in cocoa seedling nursery. Methods Cocoa pod waste was composted in static vessels, […]
Purpose Keratinous wastes are the solid environmental pollutant generated from poultry farms, slaughterhouses and barber’s shops. The aim of the present study is the degradation of keratinous wastes in an eco-friendly way by biological methods, which should further be helpful to reduce the wastes and recycled into valuable feed and fertilizers. Methods Degradation of keratinous […]
Purpose The region of Souss-Massa generates huge quantities of organic horticultural wastes estimated up to 1,307,465 tonsyear-1 . Fruit and vegetable producers are asked to process the organic wastes because of the GlobalGAP certification requirements. As a result, there is a need to assess the existing composting plants at regional scale, to improve their efficiency, […]
Purpose Guarantee the product protection and correction of errors, to improve the costs derived from quality defects and to reduce the final over control. Methods In this paper, the Hazard Analysis and Critical Control Points system is applied to the processing line of compost used in the cultivation of mushrooms and other edible cultivated fungi. […]
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 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 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 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 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 […]
