The changes in crop yield and soil physicochemical properties were investigated in fluvio-marine paddy soils with subsurface drainage. Bulk density and soil hardness decreased with a 1 year rotation. Soil pH was high in soyabean-barley rotation plots, organic matter content decreased in all plots except the 1 year rotation plot. Average P2O5 and exchangeable K and Ca contents increased in rotation plots.
