| Abstract: | Effect of sub-soiling on the physical characteristics of pseudogleys. . Physical studies on eight soils that had been sub-soiled over a range from two to twelve years before, showed that after two years the loosening of the subsoil was still god. The soils that had been sub-soiled eight to twelve years before were only slightly better than the untreated ones. Available water capacity for plants could not be increased. On the other hand it was possible to decrease mechanical compactness of the soil and to cultivate the soil earlier in the year. |
