Abstract: | To evaluate the long term effects of different cultural practices in the desertification combat, a
comparative study between a dryland conservative cropping system of cereals and another more
traditional one was done. The conservative system has had direct seeding along 10 consecutive
years, while the traditional one has had soil tillage. On a soil of the type Chromic Vertisol in Portugal
the continuity of the porous space and therefore the water dynamics of the soil were evaluated using
2D images. To have a better representation of the area under study, soil samples of 250 cm2 were
analyzed. The results, demonstrated that the conservative system, induces an increase of the porous
space continuity in depth. Thus, the cultural conservative practices produce alterations in the water
regime of the soil, being an important strategy to adopt, as intervening factor in the hydrologic cycle
and as a concrete action against desertification. |
