Precision treatment and sowing or planting method and device

Abstract

Disclosed is a device for selectively applying a dressing composition including an agricultural product and component and at least one adjuvant/carrier component to a plant propagation material externally from the device during sowing and/or planting, and for discharging the dressed plant propagation material onto an underlying surface, including: a. a reservoir container (), b. a separating device () to separate plant propagation material (K) fed from the reservoir container and to output them individually, c. a sensor unit for determining at least one environmental condition when the device is in use, and d. an application assembly () configured to selectively apply an aliquot of a dressing composition to the separated plant propagation materials during free-falling after the point of discharge from the device, wherein the assembly () includes: i. a sensor () for measuring the trajectory of the seed while falling, ii. a controller () for calculating the trajectory and for coordinating and applying the dressing composition; and iii. an outlet device for dispensing the dressing composition.
