| Abstract: | The content of humin and ratio of H/F in surface horizon of soils increases with the following order:original soil (red earth) < percogenic paddy soil < periodically waterlogged paddy soil < gleyed paddy soil.Fed-o/Feo ratio good genetic index for dividing paddy soils developed under different water regimes.This ratio in diagnostic horizon (W) of periodically water logged paddy soil profile is much higher than that in other horizons.The magnetic susceptibility X value of paddy soil is much lower that that of their corresponding orginal soil derived from the same parent materical. |
