| dc.description.abstract | Agricultural waste utilization is vital to control the increasing need of shortage of disposal area. nut and Soybean Husk have been obtained from agriculture wastes and they are dumped into not sanitary landfills and water bodies and treatment of the environment, and these residues should be handled in a suitable method to keep away the environmental impact. Therefore, in this study, these agricultural wastes were converted into biofertilizer by employing windrow composting approach with the aim to obtain soil conditioner and increase the environmental influences. In this study, response surface methodology with CCD has been used in production of biofertilizer from mixture of nut and Soybean husk and the biofertilizer parameters (particle size, pH, and moisture) have been optimized and to obtain the corresponding optimized Nitrogen (N), phosphorus (P) and Potassium (K). The optimal Particle size, pH, Moisture content, Nitrogen (N), phosphorus (P), Potassium (K) and Desirability values were 1.000 mm, 6.864, 73.924%, 2.484%, 1.544%, 0.987% correspondingly. The Physico-chemical analysis of the biofertilizer were done after 60 days composting. The Physico-chemical analysis results were No bad odour, Dark Black Colour, EC of 9.8±0.8 ds/m, ratio of C/P of 29.4±0.15, exchangeable amount of potassium of 0.99±0.01%, pH of 7.9±0.2, volatile matter of 51.4±0.3%, moisture content of 22.4±0.16%, available phosphorous of 1.54 ±0.01%, total nitrogen of 2.48±0.1%, ratio of C/N 17.1±0.1 and total organic carbon 31.13±0.2 %. So, organic fertilizer from Nut and Soybean Husk had verified its appropriateness to employ as green fertilizer. | en_US |
