Abstract

The article is devoted to the problem of water quality around irrigated soils. It was discovered that flushing of the fertile layer occurs on terrains near protected watersheds because of destroying irrigation procedures. The modernization of irrigation machines is suggested as a solution of the above-mentioned problem. The technological features of circle sprinkling machines (SM) in the conditions of complicated soil relief are defined by their supporting, tow-grip crossing capacity and slipping of carts on the slope. The operating results are given according to evaluation of SM work in difficult conditions with the picture of their changes in the diagram dependences. The above-mentioned devices help to create environmentally friendly and energy-saving solutions to enhance reliability of SM while watering sloping lands. The scientific conception as well as methods of searching for means and techniques of providing SM highly efficient work on complicated soil relief that stipulate its safe and qualitative maintenance together with reducing power and water consumption and costs for building irrigation systems are defined. The practical value of the work consists in the ability to use the investigation results for developing and creating SM modifications for complicated soil relief, for engineering by their means irrigation nets that altogether determine efficient usage of machines while reducing power and water consumption and providing soil friendly technologies of watering.
