Paddy soil derived from red soil 红壤性水稻土
the paddy soil reclaimed from cultivated red soil 红壤性水稻土
It was shown that the contents of Feo, Fed and Fee and the ratio of Feo/Fed were lower in rice rhizosphere grown in paddy soils, and the same was true for Fee content in red soils. 红壤中除络合态铁的根际内外分布趋势与水稻土相同外,其余均与水稻土相反。穆斯堡尔谱特征表明,根际中氧化铁的四极矩分裂较大,内磁场较低,即根际中氧化铁被活化。差热分析结果表明根际土的持水力强于非根际土。
