Improve crop performance and sustainability through better control of nitrogen
N-Lock was developed to slow down the conversion of ammonium to nitrate and keep nitrogen available to crops for longer to optimise yield and quality.
It allowed farmers to improve nitrogen efficiency in maize, cereals and oilseed rape.
Trials of this product showed average yield increases of +10% in maize and +4.7% in winter wheat.
What's more, it improved farm sustainability by reducing nitrogen losses by up to 50% through leaching and greenhouse gases.
Corteva nitrogen stabiliser products feature Optinyte™ technology and are sold under the N-Lock™ and Instinct® brands. Find out how Optinyte technology works here.
