The country is using these fertilizers N, P, S. Zn and B without a proper validation of requirements of the crops. We are using the fertilizer in all sorts of soils such as acid soils, Vertisols, and in lowland arid soils. My fear is on the continuous use of S and B in acid soils.

Dear
where is your study area? hope though it needs still more validation the ATA had a preliminary soil fertility atlas work for all regions. and documents are available online and detailed research for cross validation of the amount applied as per site specific is open and highly encouraged.
