The Recent Trend of Paddy Soil Classification in Japan

  • Takeshi Matsui

Abstract

In Japan, several schemes for paddy soil classification have been proposed, but the general agreement has not yet been, reached. Kamoshita(l940)(1) was the pioneer of this field. He originally introduced the modern concept in pedology into the paddy soil classification, and established the following soil types: Bog soils, Half-bog soils, Meadow soils, Gray lowland soils and Brown lowland soils according to the catenary sequence based on the differences in groundwater table. This scheme for paddy soil classification and its variations have been applied to various scientific and administrative soil survey projects in Japan, for example, to the Land Classification Survey sponsored by the National Land Agency, and to the Fertilizer Reclaiming Program by the Ministry of Agriculture and Forestry.
