Abstract
A method for treating plants with respect to estimated root zones 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 or nozzle control module adjusts a lateral offset of a spray pattern of a nozzle assembly of one or more nozzles based on the size, diameter or radius to target alignment or maximization of overlap area of a crop input directed to a strip or zone with respect to the corresponding root zone.
