Mathematical modeling of process of an operational parameters choice of watering techniques, which can be used as the theoretical basis, allowing making multiple numerical experiments for the purpose of results reception for a concrete irrigated site, is considered. Article is recommended for researching and other organizations at designing new and reconstruction of existing sites, and for the operational organizations at decision-making of a choice of technology and watering techniques

The technique of a choice of the directions of restoration of the intraeconomic irrigating network, allowing to estimate the most effective of an existing number sprinkler irrigation machines (SIM) for the given site is offered in this article, taking into account the presence of an existing network, financial possibilities of the customer, a choice of a way of an irrigation etc. Estimation of the chosen way of restoration of an intraeconomic irrigating network is offered to be spent on three indicators: resource, technological and complex

The article presents constructive-technological schemes for sprinkling machines “Sprinkler console front” (SCF) series and hydraulic calculation of water supply components

The article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization

The technique of the decision of a problem of technical and technological optimization of the acquisition and seasonal use of sprinkler irrigation machines, under available characteristics of distribution of the casual sizes of deficiency of water consumption of the chosen culture, in the concrete to agro- climatic zone is offered in the article. The basic condition of optimization, in the modern economic conditions, definition of an optimum indicator is recoupment of capital expenses for modernization or the device of the bringing networks, acquisition of sprinkler irrigation machines (SIM) and the organization of watering

Technologies and agro technical requirements to sprinkling machines depending on its flow, the area of irrigated area and agro-climatic zone are presented in the article
