The present invention relates to a method for transport and storage of fertilizer compositions. The nutrient component of the fertilizer composition, in the form of a melt, solution or dispersion is mixed with a hydrocarbon component and at least one emulsifying agent under intensive stirring for forming a water-in-oil type emulsion in which the discontinuous phase comprises the nutrient component and the volume phase ratio, discontinuous phase: total volume is in the range of 0.85-0.95. Said composition which may comprise 0-60 weight % solid nutrients and minor amounts of micronutrients are transported by ship, tank, rail cars or pipe line to storage and applied directly on the plants or crops and can be spread on the field or the emulsion is demulsified prior to application. The nutrient component, for instance urea, ammonium nitrate or calcium ammonium nitrate melt may be supplied directly from the fertilizer plant and emulsified with a hydrocarbon. |
