The right source matches fertilizer type to crop needs, to ensure a balanced supply of essential nutrients, considering both naturally available sources and the characteristics of specific products, in plant available forms.
The right rate matches the amount of fertilizer to crop needs, by assessing and making decisions based on soil nutrient supply and plant demand.
The right time makes nutrients available when crops need them, by assessing and making decisions based on the dynamics of crop uptake, soil supply, nutrient loss risks, and field operation logistics.
The right place applies and keeps nutrients where crops can use them, by addressing root-soil dynamics and nutrient movement, and manage spatial variability within the field to meet site-specific crop needs and limit potential losses from the field.
