Dataset: Effects of Soil Management on Dissolved Organic Carbon and Subsurface Organic Matter Stabilization in Mediterranean Perennial Cropping Systems.

his dataset includes soil physicochemical and biological variables measured in Mediterranean vineyards and olive groves under cover crops and tillage management. Data were collected at two depths (0–10 and 10–30 cm) and include SOC, WEOC, E4/E6 ratio, SUVA254, and enzymatic activities. The dataset supports the assessment of soil organic matter quality and management effects in semi-arid agroecosystems.
