Analysis of technological and design schemes of machines for applying liquid complex fertilizers

Plant additional fertilizing is one of the main operations for plant development, since the degree of its nutrition, and therefore its development, will depend on the correct application of fertilizers (in terms of timing and doses). Liquid ones can be applied using sprayers or a multi-injector. We also propose to introduce a pneumatic system into the design of the disk, namely, into the passage hole of the tooth, which will allow it to be blown after the tooth is found in the soil, contributing to the correct operation of the multi-injector. This design will allow working in the field even on waterlogged soils without violating agrotechnical requirements by eliminating the sticking of the hole on the needle of the multi-injector disk.
