Urea 46 % N is a highly concentrated nitrogen fertiliser, in amide form, in the form of white granules. Due to the very good solubility of urea in water and legal requirements, this fertiliser should only be applied foliarly at a concentration adapted to the requirements of the species fed and the development stage of the plant. This must be done with due observance of the relevant safety and dosage rules and application technology to avoid damaging the sprayed plants.
