METHOD OF UNDERGROUND FERTILISATION OF AGRICULTURAL CROPS Russian patent published in 2008 - IPC A01C23/00 

FIELD: agriculture.

SUBSTANCE: method implies supplying liquid fertiliser in the direction of crops root system. Parallel perforated pipes are embedded into the soil at the depth below that of basic tillage, on the one side pipe ends are blocked, the other pipe ends are led out to the daylight and connected to the liquid fertiliser reservoirs under regulated pressure. Carbonic acid H₂CO₃ is used as the liquid fertiliser; during crop growing season it is periodically supplied to the perforated pipes from the above reservoirs thus pressing out carbon dioxide which moves up through the soil voids and is converted into nutritional substances for the crops by interaction with the soil microflora.

EFFECT: method ensures introduction of fertilisers directly under the crops root systems during growing season and facilitates production of nutritional substances for the crops in the soil, mainly in droughty conditions.
