Direct Spreading Machine

Abstract

Mechanical tillage of the soil is considered a powerful factor in regulating its fertility. Long-term intensive cultivation of the soil ­leads to mineralization of organic matter. The application of highly intensive land cultivation systems in agriculture has been one of the reasons for weakening soil fertility. At this time, it should also be taken into account that 40% of the energy consumption for the cultivation of agricultural plants, and 25% of the labor consumption according to the total volume of work, falls on soil cultivation.

 In this regard, it is of great importance to search for ways to minimize the main cultivation of the soil without reducing the productivity of the plant. From this point of view, technologies of minimum and zero tillage of the soil in the sowing of grain and grass are taking their place as promising technologies in the world experience. However, the development of this method, whether in terms of technological or technical support, is currently experiencing the phase of comprehensive study of its individual issues. Our research in this direction has shown that ­the successful implementation of direct seeding technology, either for grain in the harvested field or for grass seeding in grasslands to improve the fodder base, depends on the level of scientific justification of the seeding machine. From this point of view, it is very relevant to build a dynamic model of the sowing machine for direct sowing of grain.
