FIELD: agriculture.
SUBSTANCE: system for cultivating soil with an ultra-high-pressure liquid jet from an agricultural tool contains a frame, an ultra-high-pressure liquid pump located on the frame, a set of ultra-high-pressure pipelines fluidly connected to the ultra-high-pressure liquid pump, and at least a first nozzle for injecting a liquid jet into the soil and a second a nozzle for injecting liquid jets into the soil, fluidly connected to an ultra-high pressure liquid pump through a set of ultra-high pressure pipelines. The first and second injection nozzles are configured to prepare the soil for seed introduction by creating a plurality of furrows. The first nozzle for injecting a jet of liquid into the soil is configured to create a first furrow having dimensions for receiving one or more seeds. The second nozzle for injecting a jet of liquid into the soil is configured to create a second furrow near the first furrow and inject an agricultural additive into the second furrow near one or more seeds in the first furrow. The nozzle for injecting into the soil for an agricultural tool with a jet of ultra-high pressure liquid contains a housing configured to receive ultra-high pressure liquid and fertilizer. The housing forms a mixing chamber configured to mix fertilizer with ultra-high pressure liquid, and a nozzle located in the housing and fluidly connected to the mixing chamber. The nozzle is shaped to deliver a mixture of fertilizer and ultra-high pressure liquid into the soil in a stream of liquid. The housing system is fluidly coupled to the housing and configured to provide fluid to substantially enclose a stream of liquid between the nozzle tip and the soil surface. The housing system is controlled by an on-off valve to selectively activate the coverage. The system for cultivating soil with an ultra-high pressure liquid jet for an agricultural tool contains an ultra-high pressure liquid pump, a set of ultra-high pressure pipelines fluidly connected to the ultrahigh pressure liquid pump, a nozzle for injecting a liquid jet into the soil, fluidly connected to the ultrahigh pressure liquid pump through a set ultra-high pressure pipelines. The injection nozzle is configured to prepare the soil for introducing seeds. An input system is connected via a fluid medium to a nozzle for injecting a jet of liquid into the soil through a pipeline for liquid fertilizers. The liquid fertilizer pipeline is connected to the vent pipeline to prevent at least either contamination or backpressure of the liquid fertilizer pipeline. The input system is configured to supply an agricultural additive to a stream of liquid formed in the nozzle for injection. The method of operating a soil cultivation system with a jet of ultra-high pressure liquid of an agricultural tool for preparing soil for introducing seeds, including a plurality of injection nozzles fluidly connected to an ultra-high pressure liquid pump through a set of ultra-high pressure pipelines, provides for: forming at least a first furrow in soil using a first injection attachment and a second injection attachment; periodically introducing seeds using a sowing device into a first furrow formed by the first injection attachment; periodically using the second nozzle to introduce the additive into the second furrow; and periodically applying a third injection nozzle to at least one of the first and second furrows to deliver a jet of liquid to promote soil collapse in the corresponding furrow.
EFFECT: favorable conditions for sowing are provided and soil erosion is reduced.
