The main purposes of the project are to study the chemical composition of soils in areas of irrigation which were withdrawn from agricultural production because of strong salinization, and to develop a technology for planting salt-tolerant cultures on such lands. The main tasks of this year: (1) to wash out strongly salinized soils in the areas which were withdrawn from agricultural rotation in Kazakhstan, Priaralia, up to the threshold level of salt toxicity in the 1-m-layer of soil; (2) to plant rice, lucerne (alfalfa), melilot and saflor on the lands that were ponded in 1997 with a water norm of 9700 m3 ha−1.An experimental site was established on the left bank of the Syrdarya River, within the Kzyl—Ordinskiy area of irrigation, where the area of lands withdrawn from agricultural rotation exceeds 30 000 ha.
