METHOD AND AGROBRIDGE FOR BRIDGE IRRIGATION AGRICULTURE WITH MINIMUM SOIL CULTIVATION Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: method involves agronomical procedures with direct contact of working tools with soil and plants and noncontact procedures. Direct contact procedures include those corresponding to natural plant growing conditions. Such procedures involve cultivation of soil on rectangular plots sown with single crop or mixture of crops. Plots are divided into strips, with strip width being multiple the working tool width. Noncontact procedures involve procedures accomplished during standing period by advancement of bridge and performing differentiated operations for each strip in accordance with predetermined program or signals generated by sensors. Agrobridge has carts with drive, girder with guide, movable platform, working tools for performing agronomical operations, power and water takeoff device, pipeline with sprinkler nozzles, and steering system. Agrobridge has two systems. First system is adapted for performing procedures free from contact of working tools with soil or plants and is made in the from of pipeline. Second system is adapted for direct contact of working tools with soil and plants and is made in the form of two standard subsystems. EFFECT: wider regeneration of soil fertility and agricultural productivity, useful ecologically safe utilization of natural sources, reduced power and material consumption. 3 cl, 6 dwg
