  • Welcome to Soil Science Laboratory


    We are studying soils which support life and food production. Our primary disciplines are "Properties, genesis, classification and utilization of volcanic ash soils" and "Soil-plant interactions".

    • High sensitivity elemental analysis and characterization of volcanic ash soils based on their elemental composition
    • Establishment of a database on the properties of volcanic ash soils and their international classification
    • Initial genetic processes of soils derived from lahar deposits and improvement of their soil productivity
    • Exploration of sustainable soil managements based on soil-plant interactions and using controlled availability fertilizers (CAFs).

    Soil regions map of Japan based on a reclassification

    Soil regions map of Japan based on a reclassification of the 1:1 million soil map of Japan (1990) according to the unified soil classification system of Japan --2nd approximation (2002)-- was made (Kanno et al., Pedologist: 52: 129--133, 2008).

    Phosphorus foraging root growth of Brassica and buckwheat roots

    In a nonallophanic Andosol with low available P content, lateral roots of Brassica plants and buckwheat roots show spectacular growth at the interface between a P fertilizer and the soil. Although we used dicalcium phosphate dihydrate (DCPD) suspended in alginate gel beads in the following photo, similar root growth was observed when polyolefin-coated monoammonium phosphate was used as a P fertilizer.

    Changes in element concentration of tephra with andosolization

    In andosolization, element composition is very different between the original tephra and soil formation products. The changes in the element concentration of immobile elements can be roughly approximated by weight loss of tephra.
