Abstract

Field incubation was conducted by resin core method to determine rate and amounts of nitrogen mineralization of top soil under the forest along the climatic zone in Japan. Annual rate of mineralized nitrogen were high in the soils of warm and cool temperate and low in those of to sub arctic and sub tropical. Rate of mineralized nitrogen by laboratory incubation were high in the soils of sub arctic and decreasing to those of warm temperate, and has significant correlation coefficient with organic nitrogen contents in the soil. We estimated nitrogen mineralization potential in the field using rate of mineralized nitrogen of field incubation and ratio of integrated temperature during incubation in the field to laboratory. Nitrogen mineralization potential was higher than rate of nitrogen mineralization measured in the filed in the most of soils and those differences was higher in the soil of lower integrated temperature which located cooler climate. Estimation for rate of nitrogen mineralization in the filed by multiple regression model using organic nitrogen contents, ratio of cumulative temperature and soil type for was done. Estimated values were well correlated with measured values in the field. These results suggest that it was effective to estimate rate of nitrogen mineralization in the field from these factors which were easy to get from AMeDAS (Automated Meteorological Data Acquisition System) and soil map.
