. It was found that natural vegetative cover reduces both runoff and erosion by approximately 36 and 7457 times over bare ground, and 16 and 1801 times over typically planted grasses, respectively. The increase in erosion associated with the replacement of native

into the deep soil layers and so the moistening of the high bank can be significantly diminished by planting appropriate vegetation on slopes.
concentrations in water samples, except Cu, were lower than the maximum permitted concentration for the protection of aquatic life. TN, TP and metal concentrations in sediment samples from the first three sites situated downstream of Ergani Copper Mine Plant were
anthropogenic sources, particularly metallic discharges of the copper mine plant.

content, and plant macronutrients were compared between sites where casuarinas dominated versus sites where casuarinas were absent. A multivariate ordination showed that casuarina-dominated soils were more similar to one another than to non-casuarina soils

In recent decades it has become continually more apparent that steady population growth has caused the decline of many species of plants and animals that share the planet with us, has changed our global climate and has exacerbated numerous other
N.I. VAVILOV a trouvé une ressemblance entre les plantes cultivées en hautes montagnes et leurs analogues des hautes latitudes. Le mouvement de l’agriculture vers le Nord par le semis des cultures est important pour l’indépendance agro-alimentaire

Les AA. étudient la dynamique de l'humidité du sol dans un bassin agricole expérimental situé dans la partie centrale du Douro. Ils analysent l'évolution de la quantité d'eau édaphique nécessaire aux plantes à partir de l'Indice de Déficit Hydrique
