Purpose The anaerobic digester for dead animals is the most eco-friendly and cost-effective way to dispose of this waste. The aim of this study was to evaluate the removal efficiency of organic matter and pathogenic microorganisms by an anaerobic co-digestion of whole dead animals and manure, both of swine origin. Methods Two test digesters coated […]
Purpose Humic Acid (HA), a plant’s growth promoter readily available in compost was found to have insect repelling functional groups. This study was conducted to investigate the pesticidal ability of HA extracted from Empty Fruit Bunches (EFB) vermicomposts at Carbon to Nitrogen (C:N) ratio of 25, 30 and 35. Methods The vermicomposts were prepared using […]
Purpose The present study was aimed to investigate the effect of a bovine manure vermicompost leachate (BMVL) on growth, total chlorophyll content and yield of pepper (Capsicum annuum L.) hybrid Nathalie. In pepper, the effects of BMVL had not been studied before. Methods Six dilutions of BMVL (1:10, 1:20, 1:30, 1:40, 1:50 and 1:60 v […]
Purpose In Argentina, pig slurry (PS) is spread in surface with N losses in ammonia form. Different methods to decrease these emissions are available, but there is poor information about their impacts on the soil-plant system. The objective of this study was to compare the effects of different PS application methods on the soil quality […]
PurposeThe increasing demand for phosphorous for the production of mineral fertilizers forces the continuous development of research and new technologies in the field of obtaining it from sources other than phosphate rocks. This paper presents an analysis of optimizing the combustion parameters of chicken manure in the aspect of phosphorous recovery. Methods The combustion process […]
Purpose An attempt to improve the quality and quantity of chili production through good and effective nursery still needs some development and advancement. Polybag as seedling pot made from polyethylene has non-biodegradable properties that causes environmental impacts, so alternative biodegradable pot which is derived from renewable organic material, namely BioPot, is urgent. The suitable BioPot […]
Purpose ThePresent study was conducted to investigate the effectiveness of locally available organic mulches on moisture retention, yield and irrigation water use efficiency in tomato crop. Methods The crop was grown in a randomized complete block design using pine needle mulch, wheat straw mulch and rice straw mulch as treatments and no mulch serving as control. […]
Purpose There is an increased demand for proper utilization of wastes to benefit humans especially as it relates to generation of economic gains. Although the agro-based industry and the petroleum industry contribute to high levels of waste generation, it is possible that the wastes from the agro industry could be used for management of petroleum […]
Purpose Nowadays various studies have been carried out on the possibility of using different types of organic waste compost as a much cheaper and more affordable alternative to peat moss. In this research, different rates of peat moss, vermicompost, municipal wastes compost and palm waste compost were used in combination with perlite and zeolite on […]
