Aim of the study The aim of the study is to present environmental problems related to the intensive cultivation of cotton in the climatic conditions of Central Asia. This problem has been related to the pressure to increase yields by systematically increasing the applied irrigation rates. At the same time, other problems arise, such as ownership changes, water charges, and other issues. Material and methods Case study method was used in the present work. The material was collected by co-authors from Kazakhstan during many years’ experimental and monitoring work. Results and conclusions The results of field studies concerning the analysis of the condition of irrigated land on the flagship Makhtaaral facility showed a systematic deterioration of soil physical indicators as well as: • a reduction in the drainage efficiency of irrigated land, • an increase in the groundwater level above the critical depth, • an increased level of soils salinity, • an impact of washing on soil alkalisation.
