Turli yaylov fitomeliorantlarining tuproqning sho‘rlanish darajasiga ta’siri

Abstract

The article presents the results of a study on how desert forage plant species recommended for sowing to increase the productivity of degraded desert pastures affect soil salinity. Conclusions were drawn by comparing the salinity levels of soils under the influence of the phytogenic fields of phytomeliorant species such as black saxaul, chogon, izen, teresken, keyreuk and Paletsky’s cherkez with control values (soil outside the phytogenic field). Salinity levels were determined by measuring the dry residue in the water extract. It was found that forage species such as black saxaul, chogon and keyreuk increased the soil salinity level 9.75-13 times compared with the control. It is concluded that Paletsky’s cherkez, izen and teresken are advisable for phytomelioration measures on non-saline soils.
