In the media Stopping erosion in leeks cultivated on ridges

Field of leeks

Prevention of runoff of water, fertile soil, fertilizers and pesticides in ridge crops on erosion-prone plots, comes down to roughening the soil in the intermediate ridge as much as possible to increase infiltration capacity. You can do this with thresholds, as in potato cultivation. But we also examined other methods, such as tilling, for their practical feasibility and their erosion-reducing effect. Any coarsening of the intermediate ridge led to less erosion in the tests laid out. Thresholds proved to be the most resistant to heavy rain.
