Examined factors and prediction of soil nitrogen mineralization after middle rice [Oryza sativa] growth

We examined factors of soil nitrogen mineralization in the middle and later part of rice growth (after July), and obtained the following results. 1. For Gray Lowland soil, coefficient of determination in a simple regression analysis was about 0.7. This analysis was between the cumulative effective t...

Summary:We examined factors of soil nitrogen mineralization in the middle and later part of rice growth (after July), and obtained the following results. 1. For Gray Lowland soil, coefficient of determination in a simple regression analysis was about 0.7. This analysis was between the cumulative effective temperature and the soil liberalization in the middle and later part of rice growth, but the coefficients of determinations for the other
