The life on Earth depends on the health of soils. Ukraine joined to the implementation of the European Green Deal for the ensure climate neutrality, protect soils, ecologization and improve human well-being. Soil salinity influences on the soil quality, ecosystem services, productivity and food security. The results of studying the effectiveness of over deep plowing (on 75 cm) with the manure (100t/ha) for reclamation of salt-affected chernozem ordinary are given. Such processing ensures the extraction of reserves of calcium salts from deep layers to the soil surface. This technique is called self-amelioration of saline soils. In this variant soil decompaction, improvement of water-physical properties and an increase of the humus horizon were established. The soil buffer capacity against alkalinization increased as a result of an increase of the calcium content (up to 8.3-8.7%) and the saturation of the soil absorbing complex with calcium. The content of absorbed sodium and potassium cations decreased from 6.6-7.0 to 4.3-5.2% of the total absorbed cations. The yield of crops on this variant increased on 21-38%. This agromeliorative technique had a longer effect than ameliorants.
