Distribution of zinc fractions and its association with soil properties in some rice-wheat growing soils of Jammu region, India

Distributions of different zinc (Zn) forms in seven blocks of rice-wheat growing soils of Jammu region were studied. Understanding the Zn distribution in soil is important for efficient and effective management of the fertilizers recourses and to achieve a higher productivity rate. Sequential extraction scheme was used to fractionate Zn into Water Soluble + Exchangeable (WSEX), Organic Complexed (OCx), Amorphous sesquioxide (AMOX), Crystalline Sesquioxide (CRYoX) and Residual zinc (Res Zn).
