Purpose The purpose of this study was to assess the efficacy of inorganic additives during the humification of poultry waste and rice husk. Methods Poultry waste mixture was treated with aluminum sulfate 3% and rock phosphate 2% during co-composting of mixture in mechanical composter and evaluated the potential of humification and compost nitrogen mineralization in […]
Purpose Intensive agriculture activities in small holder farming systems are declining over all soil nutrient status. The present study is conducted to compare the soil health and plant growth attributes under rice cultivation among different organic amendments. Recycled waste of rice–wheat agrosystem is utilized to determine optimal sustainable solution for hilly areas. Methods Randomly blocked […]
Purpose Improving physio-chemical properties under irrigation regime by using natural conditioners to achieve the highest possible crop yield and water productivity. Method A field experiment was conducted in a split-plot design with three replicates by addition of canal clay scouring (CS) and compost (CO) during two consecutive growing winter seasons of 2018/19 and 2019/20. The […]
Purpose The deterioration of agricultural soil can be alleviated by maintaining an appropriate level of soil organic matter by using organic amendments such as compost and biochar. The aim of this study was to investigate the effects of olive waste-based compost, wood-based biochar and their combination on the chemical and microbial properties of loamy clay […]
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 Soil acidity and nutrients deficiency are the major constraints causing low crop yield and food insecurity in the highlands of Ethiopia. A field experiment was conducted in northwestern Ethiopia during 2018 and 2019 cropping seasons to study effects of compost and lime application on soil properties and wheat yield. Method The treatments consisted of […]
Purpose The decreasing number of peatlands has driven the search for new cultivation substrates. The aim of this study was to evaluate the use of different composts as growing media in the production of vegetable seedlings (pepper and tomato). Method Composts were produced from: discarded carrots (ZC), fats (FC), and biosolids (BC) from the dairy […]
Purpose Raw and composted oil-cakes of neem, madhuca and simarouba were evaluated for their effect on plant growth, yield, and management of Alternaria tenuissima leaf spot disease, and rhizosphere microorganisms in chilli crop. Method The oil-cakes were composted in simple pits containing a mixture (6:1:1) of individual oil-cake, soil and rice straw. Growth promotion and […]
Purpose This study aimed to investigate the effects of compost and vermicompost of municipal solid waste application on the growth of Dracaena marginata tricolor. Then, the results of foliar application of compost tea and vermicompost tea on the plants were examined. Method Experimental treatments included compost and vermicompost of municipal solid waste in proportions of […]
Purpose Soil is an important accelerator for biodegradable processes. Soil resource circulation concept by using the compost from the previous crop as cover materials for the recent composting mass was evaluated as it contained soil and amorphous Fe as an energy source. Therefore, this research was focused on the possibility and the changes in the […]
