MECHANICAL SOIL TILLAGE IN ITS HIGHEST AND LAST STAGE
- 1 Аграрен университет, Пловдив, България
At the present stage soil tillage is done mainly by applying the principles of mechanics. Its development is in three directions: improvement of the working bodies, increasing the productivity of agricultural machinery and power of tractors. All these directions lead to the accumulation of a wide variety of attachments, very large in size and mass of agricultural machines and tractors, which ultimately go to its limits. These features of the present-day stage are exhausted. It is necessary to look for other methods for tillage of the soil, using other principles of the physics or other areas of science.
