The influence of cover crops and tillage on water and sediment yield, and on nutrient, and organic matter losses in an olive orchard on a sandy loam soil

Rainfall, runoff, sediments, nutrient and organic carbon losses from 8 × 60 m plots were measured during four hydrological years (2002†“2007) in a field trial, in which two different soil management systems were used to confirm this hypothesis: a cover crop (CC), and conventional tillage (CT) near Seville, southern Spain.
