CENTURO™ Urea STABILISED NITROGEN FERTILISER

CENTURO™ nitrogen stabiliser from Koch Agronomic Services is a next-generation nitrification inhibitor featuring the patented active ingredient, Pronitridine. CENTURO offers highly effective below-ground protection against leaching and denitrification.

WHAT IS A NITRIFICATION INHIBITOR?

Nitrification inhibitors slow the conversion of ammonium to nitrate. In the
nitrate form, nitrogen is susceptible to leaching and denitrification.
By slowing the nitrification process, more nitrogen is kept in a stable form for
longer, making it more readily available for when plants need it.
CENTURO slows the conversion of ammonium to nitrate and can hold the
nitrogen in ammonium form three times longer than without an inhibitor.

Three key benefits of a highly effective nitrification inhibitor

  • Minimise nitrogen loss from leaching and denitrification

  • Optimise nitrogen use efficiency & yield

  • Reduce nitrous oxide emission potential

HOW IT WORKS IN THE SOIL

When urea or other nitrogen containing fertilisers are applied to the soil, much of the nitrogen converts or transforms to ammonium. In this form, nitrogen is readily available for uptake by the crop. Ammonium will then convert to nitrate in about two weeks depending on the soil type and temperature. Slowing the conversion of ammonium to nitrate is key to preventing nitrogen loss – ammonium will bind to the soil whereas nitrate can move with water and is prone to loss through leaching and denitrification.

Q + A

WHAT IS A NITRIFICATION INHIBITOR?

Nitrification inhibitors slow the conversion of ammonium to nitrate. In the nitrate form, nitrogen is susceptible to leaching and denitrification. By slowing the nitrification process, more nitrogen is kept in a stable form for longer, making it more readily available for when plants need it.

Pronitridine is the active ingredient in CENTURO™ U-PRO nitrogen stabiliser, which offers highly effective below-ground nitrogen protection.​

Pronitridine contains both small and larger molecules, designed with a portion that structurally mimics ammonia, allowing it to compete with ammonia for the active site of Ammonia Monooxygenase (AMO), which slows nitrification.​

Research suggests Pronitridine acts by both temporarily blocking the active site of AMO and by binding to the AMO enzyme in Nitrosomonas bacteria, which temporarily alters the shape of the active site. 

  • Minimise nitrogen loss from leaching and denitrification
  • Optimise nitrogen use efficiency & yield
  • Reduce nitrous oxide emission potential

By slowing the nitrification process, more nitrogen is kept in a stable form for longer, making it more readily available for when plants need it. Please refer to trial results on this website for examples
