The article deals with the issues and principles of development of wide-cut sprinkler machines and irrigation equipment for the application of mineral fertilizers with irrigation water and identifies modern challenges to achieve fundamental improvements in technical and operational characteristics. The methodology of the work is based on the study and analysis of design and layout schemes, operating principles and designs of modern electrified circular sprinkler machines of leading foreign and domestic manufacturers and equipment for fertilizing them. As a result, the main directions of improvement of sprinkler equipment are identified and conceptually new technical solutions for the main units and assemblies are defined.
