Abstract: (689 Views)
Every year, more than 600,000 tons of rice husk are produced in rice mills in Iran, which are left in nature without proper use or burned. But, with biotechnological methods, it is possible to convert these agricultural wastes into compost with high content of nitrogen and minerals. Accelerating the production of high quality organic fertilizer and reducing the process time requires determining and studying the factors affecting the composting process. In this research, rotten wood waste in the presence of whey was used as an inoculum and the process was studied for one hundred days. The results showed that the process of rice husk composting decreased the ratio of carbon to nitrogen from 161.2 to 21.1 and also increased the nitrogen content from 0.28 to 1.33 percent. By studying temperature changes during the process, it was determined that the degradation of easily biodegradable compounds at the beginning of the process caused an increase in the population of microorganisms and an increase in temperature, and as the process continued, the temperature of the composting environment gradually decreased. On the other hand, the results indicated that the addition of tree bark fertilizer does not affect the quality of the compost content, but it changed the color of the product. The results of the evaluation of the produced compost showed that adding 10 percent by weight of compost to the soil had a significant effect on the length and weight of cowpea.
