Soil amorphous iron leaching and its relation with phosphorus leaching

Abstract

Abstract: Soil amorphous iron is a medium of phosphorous fixation.With washing experiment,this paper studied the characteristics of soil amorphous iron leaching in paddy soils and its relation with phosphorus leaching.The results showed that adding citric acid and glucose had a significant effect on the leaching of soil amorphous and complex iron.A significant interaction was observed between soil moisture and temperature on the leaching of soil amorphous and complex iron.There was a close correlation between the leaching of soil amorphous iron and phosphorus.

Key words: Amomum villosum, Tropical forest, Secondary forest
