Abstract

Violation of agricultural technology, the structure of crop rotations led to a decrease in crop yields, and irrational water use led to soil salinization and deterioration of the environment. This study was aimed at developing resource-saving technologies for the restoration of degraded irrigated lands in the south-east of Kazakhstan. The degraded resalinized irrigated lands were rehabilitated by the planting of salt-tolerant crops – phyto-ameliorants, treatment of their seeds, and spraying the aerial parts of cultures with PA-2,1 preparation (adaptogen) solution. Due to the intensive growth and development, and accumulation of the above-ground mass, the studied phyto-ameliorants contributed to obtaining high yields.
