Studies on the encapsulation of the commercial granular fertilizer, NPK 6-20-30, with polysulfone (PSF) as a coating were performed. In order to improve the properties of coatings, the granules of previously coated fertilizer (wet method) were sprayed with a polymer solution or pure solvent (N,N dim

Studies on the possibility of using of polysulfone as a coating for water soluble NPK granular fertilizer were performed. The coatings were formed from the polymer solutions by the phase inversion technique. The polymer concentration in the coating forming solution was 18 wt.%. As the polysulfone co

Investigations on the preparation of controlled-release fertilizer coated with polymers, have been described. The polymer materials used were polysulfone (PSF), cellulose acetate (CA) and polyacrylonitrile (PAN). The polymer coatings were formed on the granular NPK fertilizer by the phase inversion
