Abstract

                                The quality of mixed fertilizers, sometimes, suffer due to faulty mixing and also due to unfavourable physical and chemical changes of the fertilizer materials in the mixture, during storage. In recent years, super phosphate is being widely used in the fertilizer mixtures instead of using it as a straight phosphatic fertilizer. In the case of fertilizer mixtures containing urea, super phosphate and fillers like gypsum, it has been observed that there is a reduction in water soluble P₂O5 on storage. A laboratory study was undertaken to see, how far the super phosphate is affected in its water soluble P₂O5 content by mixing with urea and storing for a period of six months.
