SYSTEMS, METHODS AND DEVICES FOR ADDING AGRICULTURAL FLUID Russian patent published in 2020 - IPC A01C23/00 

FIELD: agriculture.

SUBSTANCE: device for application of liquid for introduction of liquid into soil adjacent to landing groove during planting operation contains sowing section of seeder, having an opening system for opening a landing furrow in the soil formed by the first and second side walls. Sowing seeder sowing section emits seeds into sowing groove between said first and second sidewalls when seeder sowing section moves in forward direction. Besides, the device has at least one fluid supply system adjacent to the furrow, installed on said seeding section of seeder behind said opening system and configured to inject liquid into at least one of said first and second side walls of landing fit after discharging seeds into said mounting groove. Said at least one fluid supply system adjacent to the furrow comprises a downwardly extending member having a knife, arranged in forward direction of said seeding section of seeder and liquid supply tube located on said downstream element from behind blade and in direction, opposite to said direction of forward movement of said seeding section of seeding machine. Various sensors are arranged to monitor soil properties in components interacting with soil.

EFFECT: invention will make it possible to provide monitoring of soil properties and to increase efficiency of fertilizer application.
