N-Lock™ MAX

Nitrogen Stabilizer

 •  N-Lock MAX is for farmers who want to keep nitrogen available in the root zone for longer and optimise their yield

 •  N-Lock MAX ensures the efficient use of nitrogen in cereals, oilseed rape and maize giving higher income and lower nitrogen losses

 •  Recent farmer trials have shown average yield increases of +9% in maize and +4.7% in winter wheat

 •  N-Lock MAX can be used through existing farm sprayers, or added to slurries

How N-Lock MAX works

How N-Lock MAX works

N-Lock MAX helps keep nitrogen in the ammonium (NH4+) form for a longer period of time by inhibiting the bacteria that convert ammonium to nitrite (NO2-). As ammonium is positively charged it is attracted to the negatively charged soil particles, and hence is not washed out of the rooting zone. Nitrite and nitrate (NO3-) however are negatively charged and can be easily washed down the soil profile away from the roots of the crop. Therefore N-Lock MAX keeps more nitrogen in the rooting zone for longer, which means that crops can optimise their yield potential.

Benefits of using N-Lock MAX in Maize

Benefits of using N-Lock MAX in Maize
  • The amount of nitrogen in the root zone of the soil plays a key role in delivering maximum yields at harvest
  • Current RB209 gives N Max of 150 kg for maize - this is not enough for modern varieties / husbandry methods
  • Maize requires more than 50 % of nitrogen post flowering
  • Up to 60 kg nitrogen can be lost pre-flowering
  • Applying late nitrogen is difficult without crop damage / specialist equipment
  • N-Lock MAX keeps a balance of ammonium and nitrate for maximum yield
  • You only need 1 extra tonne of maize to cover the cost of N-Lock MAX

How to use N-Lock MAX - 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 MAX 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 MAX - 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 MAX can be applied with T0's in winter cereals (see tank mix list)
  • N-Lock MAX is best applied near to the main spring fertiliser application (typically March time, or early April further north).

 

Where should you use N-Lock MAX??

  • 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
