N-Lock™ 

Nitrogen Stabilizer

Please note: N-Lock is being discontinued and has been replaced with our innovative nitrogen stabiliser product, Instinct®. You can find out everything you need to know about Instinct here.

 

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.

How to use N-Lock - Maize

  • Apply muck / digestate and plough in (February - April)
  • Option 1
    • Apply before pre-drilling cultivations +/- glyphosate
    • Incorporation - soil movement to a depth of 50 mm and min tine spacing of 20 cm
    • If N-Lock is not physically incorporated to 50 mm, then 12 mm of rainfall is required within 10 days of application
  • Option 2
    • Mix with pre-em herbicide or liquid fertilisers if rain is imminent
  • Option 3
    • Wait until rain is forecast and apply alone (can be sprayed in then rain) at 100 L/ha water volume

 

How to use N-Lock - Cereals and Oilseed Rape

  • Apply using a farm sprayer
  • Rainfall (12 mm within 10 days of application) or several nights of heavy dew is needed to get the N-Lock into the soil
  • Can be applied in the rain (when applied alone)
  • N-Lock can be applied with T0's in winter cereals (see tank mix list)
  • N-Lock is best applied near to the main spring fertiliser application (typically March time, or early April further north).

 

Where should you use N-Lock?

  • Use where nitrogen losses can be high, such as permeable soils, or soils prone to waterlogging
  • Use on high potential crops where maximum nitrogen efficiency is required
  • Use as an aid to organic manure management
  • Use where a regular supply of nitrogen to the plant is required throughout its growing cycle
