We conduct various studies on the assessment and analysis of soil microbial biomass, community and activity and interactions of plant and soil microorganisms in order to improve plant production and to maintain soil sustainability and fertility.

1) Effects of organic materials and soil conditions on soil microflora useful for plant growth and control of soil-borne diseases (Nagaoka, T.)

2) Plant root hair is important for water and nutrient uptakes and microbial interaction. We analyze the interaction of root hair and soil by the approach of molecular biology. (Tominaga, R.)
