Free-flowing, mineral oil-free granulate particles of plant auxiliary agent comprises reaction product of plant auxiliary agent containing nitrogen, phosphorus and/or potassium and waste flow of natural material containing nitrogen compound

摘要

A free-flowing, mineral oil-free granulate particles of a plant auxiliary agent comprises reaction product of a plant auxiliary agent containing nitrogen, phosphorus and/or potassium and a waste flow of natural material containing nitrogen compound(s). The plant auxiliary agent is a fertilizer containing urea or ammonium nitrate. The natural material is of vegetable or animal origin. An independent claim is included for preparing free-flowing, mineral oil free granulate particles of a plant auxiliary agent involving reacting a waste flow of natural material containing nitrogen compound with molten particles of plant auxiliary agent in presence of a solvent.
