During the study on Shaulder irrigated massif, soil salinity maps with different degrees of were compiled at large-scale 1:10000 in GIS environment. It was found that area saline soils increases depth. In upper 0-20 cm layer, 29% is salted and 50-100 up to 44% salted. The theory reclamation shows a close relationship between level concentration salts accumulating state current crop. Determination effect biopreparation carried out field studies. Pre-sowing treatment maize seeds using working solution C-1-1 adaptogen-preparations optimal technological modes developed by U.U. Uspanov Kazakh Research Institute Soil Science Agrochemistry. Maize sowing May depth 6-8 common way row spacing 70 rate 18-20 kg per 1 ha. plants sprayed phase 4-5 leaves 6-7 leaves; when corn forms first second tier nodal roots, biological product “BioEkoGum” an aqueous solution. study's findings showed depending degree salinity, yield for grain increased non-saline 40.0% compared control 71.1 c/ha. lightly medium-saline - 81.2-83.9 c/ha (62.5-63.5 C/ha), addition 30.0 32.1%, respectively. highly soils, 11.4 %, under 47.1 C/ha.
