METHOD FOR PRESOWING SOIL TREATMENT AND SEED SOWING AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC A01C7/00 A01B79/02 

FIELD: agriculture, in particular, farm crop sowing processes and agricultural engineering.

SUBSTANCE: method involves presowing mellowing of surface layer of soil; forming furrows for seeds in mellowed soil; providing compacted bed on undisturbed soil of furrow bottom; sowing seeds in furrow and embedding said seeds with mellowed soil layer from spacings; providing presowing mellowing of surface soil layer to depth not in the excess of 7 cm, with furrow and compacted bed being formed using roller; forming furrow on mellowed soil layer, with depth of furrow being not in the excess of half the thickness of mellowed surface soil layer, and compacted bed being made in the form of ridge with acute angle at apex part disposed at furrow bottom; forming furrow in lower part of mellowed soil layer by using pressure of roller. Ridge base is formed on undisturbed soil. Apparatus is made in the form of drill comprising seed hopper, seeding unit, furrow former made in the form of one or number of feeler rollers which are located on rear traverse of drill in spaced apart relation, with space being equal to distance between rows of crops. Drill is further provided with covering tool made in the form of device for covering seeds with mulching soil layer. Seeding pipes are positioned forward of covering device in single vertical plane with feeler rollers. Working surface of feeler rollers is made in the form of wedge-shaped member having height of at least 2 cm and width of apex part exceeding size of seeds to be sown. Ratio of roller width to its diameter is about 1:30.

EFFECT: reduced consumption of power for seed sowing process, increased yield of cereal crops owing to intensified field germination of seeds, and provision for creating optimal conditions for growing and development of cultured plants and slowing down germination of weeds.
