The article presents thorough information about the results of the research in the irrigated meadowgrey soils of the area where the grain was planted in the Salyan plain. The research shows that strong differences between the subsoil waters mineralization and change of their location levels were not observed in the experimental area in 2015–2018. However, in 2015 the location levels of subsoil waters changed by 2.40–2.55 m, their mineralization was – 1.244 – 2.577 q/l. These indicators changed to 2.40–2.60 m and 1.210–2.430 d/l in 2016; 2.50–2.55 m and 1.030–2.320 g/l in 2017; 2.45–2.55 m and 1.183 – 2.159 g/l in 2018. During the research the author studied the waters of Akusha canal, water-collector and drains which are used with the purpose of irrigation. It has been determined that their mineralization was 0.81 g/l, 6.663 g/l and 4.834–5.242 g/l in 2015. These indicators changed as follows: 0.675 g/l; 6.003 g/l and 4.651–4.823 g/l in 2016; 0.612 g/l; 5.872 g/l and 4.731–4.602 g/l in 2017 and 0.578 g/l; 5.752 g/l and 4.651–4.513 g/l in 2018. The agromeliorative measures have been offered for the purpose of subsoil waters decrease and their mineralization increase in the same zone taking into account all the indicators.
