1. A method of seed treatment, comprising:
separating an individual seed from a reservoir container containing a plurality of seeds;
dispensing the individual seed from the separating along a fall line past an array of sensors to detect the plurality of seeds within a sowing device;
detecting with a first sensor of the array of sensors the individual seed from the dispensing;
detecting with a second sensor of the array of sensors the individual seed from the dispensing;
calculating an impact location for spraying of a seed dressing of the individual seed and a time delay for spraying of the seed dressing of the individual seed based on the detecting with the first sensor and the detecting with the second sensor, wherein the impact location is along the fall line of the individual seed and outside the sowing device; and
spraying the seed dressing from an application nozzle onto the individual seed while in free fall at the impact location and with the time delay to produce a treated seed, wherein the treated seed lands on an underlying surface.
