Abstract
In this article, speak about the reveal the main causes and ways to eliminate the problems of salinization and hydromorphism of soils in the Republic of Tajikistan, since salinization is one of the main stressors, that limit the growth and productivity of agricultural plants. The existing studies show, that there are two ways of integration: passive and active. Passive, through the selection of salt-resistant and moisture-loving tree crops and their transpiration capacity. Active also offers a special reclamation survey of the sides of drains and reservoirs and the use of reclamation measures aimed at achieving good survival and survival of young seedlings. Bio-drainage consisting of local tree species under a certain arrangement can transpire a volume of water commensurate with and even superior to pumping them out by vertical drainage wells. This indicates, that it is possible to remove local ground water pressure and change the existing structure of the ground flow in the agricultural landscape.

Among the unfavorable factors for planting and growing crops, the most common is the impact of climate change is widespread

Transpiration capabilities of plantings can be enhanced by creating an undergrowth of shrubs or semi-shrubs
Summary
Among the unfavorable factors for planting and growing crops, the most common is the impact of climate change is widespread. A retrospective analysis of available materials over many years clearly shows, that the main factors in the formation of the reclamation state of the soil cover of the irrigated zone were both natural and organizational and technical, as well as methods of development of reclamation laid down in the concept, including, as it turns out unacceptable environmental and reclamation guidelines.
