Zusammenfassung:The present invention relates to a fertilizer composition comprising solution or dispersion of nutrient compounds and method for its manufacture. The solution/dispersion constitutes the discontinuous phase of a water-in-oil type (w-i-o) emulsion having a volume phase ratio, discontinuous phase : total volume in the range of 0.80-0.95. The fertilizer composition may additionally contain 0-60 weight% solid nutrient salts and/or urea. The oil or hydrocarbon component of the w-i-o emulsion comprises mineral, vegetable or animal oils, wax or mixture of these, and the emulsion comprises at least one w-i-o emulsifier. The hydrocarbon component may also contain 0.5-6 weight% of elastomere, preferably polyisobutylene. The method comprises dissolving or dispersing the nutrient compounds at a temperature of 5-15C above the crystallization temperature of the mixture, and then add while stirring to a mixture of emulsifier and hydrocarbon, said latter mixture having been heated to about the same temperature as the former mixture. The combined mixtures are exposed to intensified stirring for 0.3-3 minutes.
