What is Efficie-N-t 28


It is a liquid foliar nitrogen fertiliser based on urea polymers of variable lengths. The longer the chains, the slower they breakdown, resulting in a phased release of nitrogen over a total of 6 to 8 weeks.


The polymer chains break down to release nitrogen as amide(NH2), groups which are the building blocks of proteins, a process that is much more energy efficient than converting nitrate(NO3) 


Efficie-N-t 28‘novel chemistry delays the nitrogen availability to the crop to give a natural physiological response, avoiding the ‘flush’ growth, seen with nitrate based fertilisers. Nitrates draw in water, weakening the cell walls, making the crop more prone to lodging and attack by diseases.
