| Research Abstract |
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 NH_4-N was almost converted into the NO_3-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).
