METHOD FOR VERTICAL LOCAL MELIORATION OF SANDY AND SANDY LOAM SOILS

摘要

A method for local melioration of sandy and sandy loam soils such that soil medium loci of prolonged action is created in vertical wells of a diameter of 15- which serve as planting columns for plants, the distance between which is determined depending on the crop grown and technological stages (setting up, cultivation period), at angle of which at a distance of 65- additional similar 2-4 columns are formed. The latter are filled with a mixture of sandy loam with an organo-mineral additive, and depth thereof is determined by the depth of subsoil water and capillary fringe.
