ДИФФЕРЕНЦИРОВАННОЕ ВНЕСЕНИЕ КОНЦЕНТРИРОВАННОЙ СЕРНОЙ КИСЛОТЫ ПРИ МЕЛИОРАЦИИ СОДОВЫХ СОЛОНЦОВ-СОЛОНЧАКОВ В ЧЕКАХ

Abstract

The motley mechanical structure of soda salt licks of the Ararat valley demands a special approach at calculations of necessary norms of a chemical ameliorant and washing water. The melioration of these soils used 1 % of sulfuric acid which brought in the soil on requirement of the maximum point therefore after melioration in different points and sites of the check took place ora nonmelioration, or on the contrary accumulation of new formed CaS04 and MgS04. The application of concentrated sulfuric acid for melioration gives the chance to bring sulfuric acid on each site differentially, thus to save 25-30 t/ha an ameliorant expense, to reduce the price of development of meliorated site and evenly to meliorate the check.
