RIGHT Rate – Assess plant demand, soil nutrient supply and predict fertilizer efficiency to establish rate of application
RIGHT Time – Assess the timing of crop uptake, weather factors, and dynamics of soil nutrient supply before applying
RIGHT Place – manage spatial variability of nutrient supply, limit off field transport, fit needs of tillage system when applying
