Urea (carbamide) is the most concentrated granular Nitrogen fertiliser (46,2% nitrogen)
The amide form of Nitrogen provides long lasting nutrients to the plant. It is suitable for use as a fertiliser for basic and pre-sowing application, foliar feeding and fertilisation under all agricultural crops. When applied to the surface soil, it needs to be mixed in time. When it enters the soil, it converts to the ammonium form of nitrogen and after a few days to the nitrate form.
