Abstract
During 2005/2006 a vineyards, located in south-west of Sicily (37° 60’ N – 12° 30 E), were subjected to five different soil managements: “conventional” ( T ) soil management using up to eight soil plowing with a five furrow plow; natural cover cropping ( N ), vetch cover cropping ( V ) (Vicia sativa L.); subclover cover cropping ( S ) (trifolium subterraneum var. Clare); medic cover cropping ( M ) (medicago polymorpha var. Santiago). In the layer 0-25 cm, soil moisture, total N, NO3, NH4, and soil organic matter were determined. Fresh and dry biomass weight, and total nitrogen percentage were determined on nine one square meter subplots for each thesis. Soil erosion was measured, using a Gerlach equipment.
