Abstract
A method for treating plants comprises estimating a growth state or maturity state of a plant based on a planting date, a current date and the crop type of the plant. A root zone estimator or data processor estimating a size, diameter or radius of a root zone of the plant based on the determined growth state or maturity state. The data processor adjusts a lateral offset of a distribution pattern of a crop input or nutrient from at least one nutrient knife based on the size, diameter or radius of the root zone and safety zone about the root zone, where the at least one nutrient knife tracks a path outside of or bounded by the root zone.
