The compressor is connected directly to the reservoir for liquid fertilisers, which is connected to the hollow axis by the force manifold. There are segment windows made in the hollow axis to supply liquid fertilisers from the reservoir for liquid fertilisers into cavity of needles. Hollow needles have isolator stems in the lower part. ^ EFFECT: device has a simple design and ensures application of a strictly determined dose of liquid fertilisers in soil. ^ 2 cl, 4 dwg |
