Pluri-decennial erosion rates using SUM/ISUM and sediment traps survey in the Mercurey vineyards (Burgundy, France)

Vineyards are often considered to be among the agricultural lands most sensitive erosion. We used Stock Unearthing Measurement/Improved Measurement (SUM/ISUM) method and sediment traps volume measurements assess pluri-decennial erosion rates on a sub-catchment of Mercurey vineyards in Burgundy, France. The measured were compared local environmental conditions (such as slope, soil type, age vines, etc.) discuss role driving factors. found that mean rate was 21.4 ± 3.1 t.ha−1.yr−1 vine plots (from −3.2 1.5 53 5.8 t.ha−1.yr−1), while accumulation varied from 16.6 5.9 (upslope) 0.13 0.05 (downslope). characterized by variable error margins 7% 43% value) directly correlated with rates. Both slope (USLE-LS factor) vines identified factors Runoff is main modality higher erodibility during first years after plantation (unconsolidated bare soil); regular (every 15 20 years) backfilling eroded collected downslope can explain effect In spite control strategies, remain than what tolerated for sustainable development agriculture. Therefore, we suggest current mitigation strategy should complemented other techniques maintain soils (e.g., grass strips interrows, mulching).
