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 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
