Title : | SPECIAL TILLAGE MACHINERY FOR SOILS WITH INCREASED CLAYEY TYPE MECHANICAL COMPOSITION -MARSH SOIL CASE |
Abstract : | Today, soils in Serbia consist of over 0.40 million hectares with increased of clayey mechanical type composition and over one million ha of diversely damaged soil. These kinds of soils are potentially fertile by virtue of their characteristics, as they have good chemical properties, but their very poor physical and mechanical properties present serious problems for exploitation. Soils with clayey mechanical composition require a special tillage system that will guarantee preservation of the soil’s natural potential and fertility and preventing degradation of the soil, but with an optimal consumption of energy and labour. Agricultural machinery for tillage of the soils with clay mechanical composition should fulfil the following basic demands: arrangement of the soil surface and depth; preservation of the soil biological system; regulation of the water and air system (thus enabling efficient irrigation); conservation of the natural humidity; and insurance of rational energy, labour and resource consumption for the defined structure and production level. Ensuring a quality and steady return on planted crops requires ensuring an optimal air and water system for the soil. This means that the soil surface and depth have to be adjusted to create conditions for the conservation and rational usage of the natural humidity from the cultivated layers and from the deeper layers of the soil. The goal of the research conducted by the Institute for Agricultural Engineering of the Agricultural Faculty of Belgrade, R. Serbia, is to define the necessary parameters for the construction of machines capable of tilling soils with a clayey type of composition and to develop new solutions for tillage of soil with this type of mechanical composition. The research includes the development and verification of the effects of the new machines on physical and water properties of heavily composed soils, the consumption of energy and resources in their tillage, the agricultural returns and the development of new technologies for tillage. The primary goal of applying the new machinery is to verify the important parameters for the construction of these machines, by defining the parameters that show positive effects on the soil with a clear goal of perfecting technologies for the exploitation of the potential fertility of the soil. The chosen conditions in the present study were irrigation for two harvests. |
