Corteva Agriscience is reminding growers that Instinct, its nitrogen stabiliser product, is back in stock and available this autumn to cereal and oilseed rape (OSR) growers across the UK and Ireland. 

In trials conducted by Corteva Agriscience, data shows that arable crops can benefit from an autumn application of Instinct, which helps soil to retain nitrogen for longer. It does so by reducing leaching by roughly 50%, and reduces denitrification through greenhouse gases by 45%.

Colin Bowers, category manager for Corteva, said: “Our internal development trials showed yield responses of up to 7% and improve spring vigour in oilseed rape when Instinct is used with slurry in the autumn.”

Containing Optinyte, the active ingredient used in Corteva’s N-Lock and N-Lock Max products, Instinct will arrive on farms as a 300g formulation.

The product should be applied at a rate of 1.7l/ha, as close to the application of the source of nitrogen as possible – ideally within a couple of days either side, if not applied with slurry or digestate. Instinct can be applied to a seed bed and incorporated or simply sprayed on as a surface application.

Mr Bowers added: “When applied to the soil surface, the ideal situation is for there to be at least 12mm of rain during the 10 days following application, in order for the product to be washed into the soil.”
