Research field (1): Plant nutrient science/soil studies
Research overview:
At the culture experiment, quantity of inorganic nitrogen from decompositions of buried organic fertilizer and organic material in soil under the various environment conditions is measured and simulation model based on fluctuation of quantity of inorganic nitrogen is made by velocity analysis of the nitrogen mineralization. While, at the field experiment, quantity of inorganic nitrogen from decompositions of buried same thing in soil is measured regularly. We compare two experiment results and investigate the applicability of the simulation model about the nitrogen mineralization at fruit tree soil.
