| Fuel, feed, and fertilizer are critical resources that often must be imported. Especially for agriculturalists in developing countries, the high cost of these resources and high interest rates create significant economic problems. These economic problems, the decreased availability of renewable sources of fuel, and the need for pollution control and fertilizer conservation have forced people to look for new sources of these resources. Methane fermentation technology is one alternative that has received widespread interest in developing countries because it converts locally available byproducts into fuel, feed, and fertilizer. Through a microbial process, agricultural waste material and byproducts can be converted into valuable products. This conversion... |

| The purpose of this study was to evaluate the effect of anerobically co-digested dairy manure and food processing wastes as an organic fertilizer, and to investigate the changes in soil nitrogen and grain yield of winter wheat (Hokushin) comparing digested dairy manure with chemical fertilizer. By the incubation test, it was clear that the NH4-N was almost converted into the NO3-N for four weeks. Over the period of 101 days, 15% of inorganic N was accumulated in the soil. Between grain yields where co-digested dairy manure and chemical fertilizer were applied, there were no significant difference, but protein contents in grain were higher in co-digested manure applied than chemical fertilizer one (p<0.05). |
