Abstract
The article is devoted to the implementation of reclamation measures with the use of organomineral meliorants on saline and exposed to varying degrees of salinity soils of the Agdash district. In the experiments conducted, the positive effect of chemical meliorants made on the basis of wood and cane sawdust on saline-saline soils of the Agdash district was investigated. The indicators of the amount of chemical meliorants and the washing rate adopted during the washing season were, respectively, 10 t / ha and 8 thousand m 3 / ha. A comparison of the results obtained with the results of experiments conducted with ordinary water and with the use of drywall revealed that the data obtained during soil washing with chemical meliorants are almost twice as high as the indicators of control variants. The option of washing the soils with the use of chemical meliorants allowed to completely eliminate the salinity of the soils. At the same time, the alkalinity of the soil solution decreased from 8.1 to 7.0-7.1, and the content of the residual amount of gypsum undissolved in water in the soil increased by more than 2 times when compared with the option of washing with ordinary water, which, in turn, has a direct effect on improving the water-physical properties of reclaimed soils and increasing its fertility.
