Nitrogen MANAGEMENT
It's time for a change
nitrogen at the root zone
In the past, growers often applied more nitrogen than the crop used. They anticipated and accounted for losses of nitrogen due to leaching or denitrification. But advice now is to only apply the amount of nitrogen required by the crop to fulfill its yield potential. This advice is underpinned by fertiliser economics and environmental considerations.
Overview
There are several tools growers may adopt to improve nitrogen use efficiency. Simply applying nitrogen doesn’t guarantee it will still be there when the crop requires it. Nitrogen stabilisers such as Instinct will keep nitrogen in the root zone, optimising yield potential and reducing both greenhouse gas emissions and nitrogen leaching. Nitrogen stabilisers such as Instinct are essential tools to enable sustainable and productive agriculture.

LEACHING
Rain will wash nitrate nitrogen out of the soil and into the waterways. Instinct Nitrogen Stabiliser reduces leaching by 48%.
DENITRIFICATION
In waterlogged soils, nitrate can be converted into nitrous oxide – a greenhouse gas. Instinct nitrogen stabiliser reduces denitrification by 44%.
VOLATILISATION
Volatilisation is a process that converts usable nitrogen into ammonia gas, which escapes into the environment instead of getting into the root zone. Heat speeds up the conversion.
SOIL NITROGEN RETENTION
Instinct nitrogen stabiliser retains 28% more nitrogen during the period of peak nitrogen demand by the crop.
