Method and system for placement of single seeds one by one

A vehicle for singling out seeds from a disorderly group of seeds, and sowing the singled out seeds comprising:

• a seed wheel rotating about a rotation axis, the seed wheel having a plane which in use is angled with respect to a horizontal plane and which comprises openings that are distanced from the rotation axis of the seed wheel;
• the seed wheel rotating slidingly against a stationary back plate having a hole therein distanced from the rotation axis such that rotation of the seed wheel about the rotation axis causes openings in the seed wheel to become aligned with the hole in the stationary back plate;
• a tube connecting the hole in the stationary back plate and a temporary rest for a single seed, the temporary rest adapted to transfer the single seed to a growth medium in response to an electrical signal, wherein a distance from the temporary rest to the growth medium is no more than 5 cm;
• and
• a receiving system for receiving geographic positioning signals that are routed to a control system connected (i) to one or more movement generators that move the vehicle with respect to the growth medium and (ii) to the temporary rest to release the single seed in response to the electrical signal from the control system in order that the location of the single seed is obtained.

A sowing method comprising:

• guiding a vehicle along a predetermined path at a predetermined speed, the vehicle comprising implements for delivery of seeds onto or into growth medium and a command module that receives geographic positioning signals;
• separating an individual seed from a disorderly group of seeds;
• allowing the individual seed to fall towards a growth medium;
• halting movement of the individual seed on a temporary rest prior to the individual seed reaching the growth medium, wherein a distance from the temporary rest to the growth medium is no more than 5 cm;
• and
• releasing the individual seed from the temporary rest according to timed control signals from the command module in order to obtain a geographic position of the individual seed in the growth medium.
