Purpose The nutritional content of fermented fertilizers was determined, and the effect of its application in combination with hydrogel was evaluated in a bioassay with maize plants. Methods The fertilizers were produced in artisanal biodigesters and the bioassay was carried out in pots with CP-569 maize. The nutritional content of the fermented fertilizers was evaluated, […]
Purpose Biochar and inorganic fertilizer when co-applied have been reported to increase crop yield and enhance soil fertility. However, studies on this complementary effect on soil properties and rain-fed upland rice performance in Sub-Saharan Africa are still scanty. Methods Field factorial studies conducted over 2 years was set up to investigate the interactions between rice husk […]
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 Composting is an environmentally sustainable alternative for bioconversion of agricultural residues into a nutrient rich product that can enhance soil fertility/microbial diversity and thereby improve agricultural productivity. The goal of the current study was to evaluate the decomposition pattern of the agro-residues and assess the maturity and phytotoxicity of the composts obtained using physico-chemical, […]
Purpose In this study, the composting and co-composting potential of coffee husk and pulp with source-separated municipal solid waste (SSMSW) was investigated. Methods Coffee husk and pulp were mixed independently with SSMSW in different proportions (0, 33, 50 and 100%), and composted in triplicates with a total of 24 composting piles for 3 months. From each […]
Purpose Protein hydrolysates (PHs) have attracted much interest in recent years owing to the beneficial effects on plant growth. Feather, one of the most abundant wastes generated from the poultry industry, is rich in proteins and amino acids. It can be utilized to generate value-added bioproducts such as liquid feather protein hydrolysate (FPH). This research […]
Purpose Mushroom waste medium can be used as a source of enzymes, but few studies on animal feed improvement using it have been found. In this study, the potential as additives for improving feed efficiency was examined. Extracts from waste media containing shochu lees used for growing three mushrooms cultivation: monkey head mushroom (MHM) Hericium […]
Purpose The study presents the physico-chemical, heavy metal and spectral characterization of aerobic compost to assess the suitability of its use for different purposes generated from two different municipal solid waste dumpsites located in the cities of Solan and Mandi in Himachal Pradesh. Methods The spectral characteristics of the compost material were determined using Scanning […]
Purpose This study was carried out to compare the effects of composted kitchen waste (KW) and poultry manure (PM) soil amendments on growth, yield and heavy metal uptake in edible leaf of Corchorus olitorius. Methods Kitchen waste and PM composted for 8 weeks were applied as soil amendment at the rate of 0 (no amendment), 5, […]
Purpose A feld trial was conducted on a silty-loam soil under potato culture in NW Spain, to assess the efect of municipal solid waste (MSW) compost in a heavily fertilized acid soil. Methods Three doses of compost (0, 30 and 60 Mg compost ha−1 soil) or inorganic fertilization (~ 140 N: 120 P2O5: 240 K2O kg ha−1 […]
