Popis: To increase the fertility of neutral salt pans and improve their physico-chemical properties under intensive irrigation, it is necessary to apply a set of measures. Reclamation of saline soils should be aimed at reducing the content of exchangeable sodium in the absorbing complex, improving the chemical and water-physical properties of soils and creating a highly fertile root-inhabited soil layer. When developing salt flats under irrigation conditions, both in the reclamation and in the operational period, the processes of secondary alkalinization, salinization and salinization of salt flats of zonal soils should be completely excluded. When choosing a method for reclamation of salt pans, which ensures soil desalination and prevents their alkalinization and salinization, it is necessary to take into account the content of exchangeable sodium, the depth of occurrence and reserves of gypsum and carbonates in salt pans of salinization of salt pans and zonal soils, as well as the amount of secondary absorbed sodium and secondary soda formed as a result of exchange reactions.
