| Summary: | The Effects of Three Soil Preparation Techniques on its Structural and Hydric Conditions. The effects of three soil preparation techniques on its structural and hydric condition were studied through field experiments. The three techniques studied were soil turning-over with a mouldboard plough, no turning-over with a chisel plough and a superficial turning-over with a disk harrow. The structural and hydric condition were characterised by the dry apparent specifie weight, the permeability and the soil water content. The results showed a porous condition with mouldboard plough characterised by sub-horizontal discontinuities wich slow vertical infiltration of water and ensure the highest drying effect. Chisel plough allowed the greatest water infiltration and disk harrow ensured the lowest soil drying effect. |
