ANALYSIS OF COMBINED MACHINES FOR MINIMAL TILLAGE OF SOIL

The creation of innovative technologies and technical means to obtain high yields of grain and cereal crops plays an important role in world practice. The article provides the researchers from all over the world and many reputed companies which are manufacturing agricultural maschines have developed combined machines for minimal tillage and sowing. All of these machines combine active and passive elements for tillage, preparation for planting, as well as a planting machine. Passive elements include softening blades, deepening blades, cultivator claws, leveling blades, discs, rollers, and more. The active elements consist of working bodies that rotate vertically and horizontally or with a hanging blade. The concluding part of the article states that a new technology of minimizing soil on sloping lands in Uzbekistan and scientific research on the creation of a combined machine is being carried out in Uzbekistan. This technology eliminates water erosion on slopes and increases soil fertility.
