Key benefits
ENHANCED NUTRIENT USE EFFICIENCY (NUE)
Increase in nitrogen (N) uptake by the plant and physiological conversion of N into biomass growth - especially at higher N availability.
ENHANCED NUTRIENT USE EFFICIENCY (NUE)
Increase in nitrogen (N) uptake by the plant and physiological conversion of N into biomass growth - especially at higher N availability.
INCREASED ROOT DEVELOPMENT
Increase in root growth, leading to a further increase in N uptake capacity, especially later in the season when N becomes a limiting factor.
Increase in taproot vigour.
