The soil temperature regime is of great importance in agricultural production. The average
annual temperature of the soil surface has been around 17-19
0
С (2006-2008) and its average
monthly temperature throughout the year is distributed evenly over the same month as the air
temperature. The absolute minimum annual soil temperature was recorded in different years
(2016, 2018), in Yangier where minus 14-26

According to the Center for Hydrometeorology, the average annual precipitation is from
246.5-271.3 mm (2008) to 345.0-363.8 mm (2017), maximum atmospheric precipitation per day.

At the same time, the grouping of the soil to the mechanical composition was carried out
on the basis of the N.A. Kachinskiy classification, i.e the amount of physical clay (particle size
<0.01 mm).
Anion and cations mg-equivalent on the classification of soil salinity N.I. Bazilevich and
Y.I. Pankova’s soil salinity chemism was determined in accordance to their relativeness. (Table
