Method of ameliorization of salinated soils with heavy granulometric composition

Abstract

The invention relates to agriculture and can be used in the washing of soils with varying degrees of salinity and salinization, having a heavy granulometric composition. The essence of the invention is that in the method of amelioration of saline soils with heavy granulometric composition, which consists of mixing 40% sulfuric acid with plant sawdust, neutralizing the resulting mixture, introducing the resulting mixture into the soil, and then washing with the required amount of water, according to the invention, in the first stage, sulfuric acid, cane sawdust and sawdust are mixed in a weight ratio of 3:1:1, the prepared ameliorant is introduced into the soil in an amount of 5 t / ha, 4 They wash the soil with a water rate of 1,000 m³ / ha. In the second stage, before sowing agricultural crops, they apply a melioration fertilizer obtained by mixing 20% ​​nitric acid with cane sawdust and sawdust in a ratio of 2:1:1 to the soil, and then irrigate 4 times during the vegetation period.
