Abstract
The process consists of coating the base fertiliser with colophonium, opt. together with an inorganic substance, by adding the copophonium dispersion in organic medium and subsequently spraying with the finely-powdered inorganic salt, finally drying in a current of air at 10-50 deg.C from which the solvent is recovered. The colophonium soln. is made in an organic solvent e.g. ethyl alcohol, toluene, benzene, etc., in concn. of 350-450 g./l., and the colophonium content in the prod. is 10-50%.
