초록

The purpose of this study is identify chemicalchanges in yield components of soil using organic fertilizerfor cultivating rice and establish reasonable methods of fertilization.
In chemical change, comparing the control plot,the soil using organic fertilizer consistently for three yearsfor cultivating rice showed an increase in pH and availablephosphate in the experiment plots provided by the organicfertilizer, increase in spikelet number and 1000 grain weightin terms of yield components, and increase in yield in thethree-year experiment plots. As for the quality of brown rice,the rate of head rice showed no difference when compared tothat of the control plots. As for protein content, it was difficultto identify a statistical significance between the control plotsand the experiment plots in 2009, but since 2010, the proteincontent of the experiment plots has been lower than that ofthe control plot, indicating that fertilization of organic fertilizerwas effective in terms of rice quality. In conclusion, long-termuse of organic fertilizer improved the chemical properties ofsoil and increased yield when compared to practical fertilization.
Reasonable fertilization was identified to fertilize the nitrogencomponent of organic fertilizer to be a level of 12kg/10a
