Bulygin O. Formation of the efficient water and salt regime of dark chestnut soils at the background of vertical drainage in the area of the Krasnoznamenskaya irrigation system

The object of researches is Irrigated livery soils, their agromeliorativnoe state, terms and factors of forming of the water-salt mode. The purpose of researches is Development of measures of forming of the optimum water-salt mode of livery soils on a background vertical drainage in the modern terms of resursosberegeniya on the Krasnoznamenskom irrigated array. Methods of researches - the field; laboratory; statistical; mathematical. Results of researches: 1. For a theory - First for the terms of south-west part of COMAE the dynamic chart of adjusting of the water-salt mode is developed for all active area moistly - soleobmena by means the irrigation and vertical drainage; the mode of irrigation of wheat of winter is improved taking into account weak and middle mineralizatsii close bedding under the ground waters (PV) and by the additional running which is created by vertical drainage. 2. For practice - Results of researches in practice can be the base of informative data for acceptance of administrative decisions at computation of the resursosberegayushih modes of irrigation of agricultural cultures, modes of operations of vertical drainage on territories with the near bedding RPV. The results of researches are important and necessary for saving of fertility of livery soils and receipt of the assured harvests of agricultural cultures and are used for a reconstruction and exploitation of the orositelnih and drainage systems. The sphere of the use is the agricultural enterprises of south of Ukraine.
