Using a Rainfall Simulator to Define the Effect of Soil Conservation Techniques on Soil Loss and Water Retention

Popis výsledku v původním jazyce

In the Czech Republic, the Universal Soil Loss Equation provides the basis for defining the soil protection strategy. Field rainfall simulators were used to define the actual cover-management factor values of the most extensively seeded crops in the Czech Republic. The second purpose was to assess rainfall-runoff ratio for different crops and management to contribute to the debate of water retention effectiveness during approaching climate change. The methodology focused on multi-seasonal measurements to cover the most important phenological phases. The rainfall intensity was 60 mm.hMINUS SIGN 1 for 30 min and a plot size of 16 m2. More than 380 rainfall simulation experiments provided data. Soil conservation techniques proved to have a significant effect on runoff reduction. Conventionally seeded maize can reduce the runoff ratio to around 50%. However, cover crops combined with reduced tillage or direct seeding can reduce the runoff ratio to 10-20% for &apos;dry&apos; conditions and to 12-40% for &apos;saturated&apos; conditions. Conventionally seeded maize on average loses 4.3 Mg.haMINUS SIGN 1 per 30 min experiment. However, reduced tillage and direct seeding reduce soil loss to 0.6 and 0.16 Mg.haMINUS SIGN 1, respectively. A comparison with the original USDA values for maize showed that it is desirable to redefine the crop cover factor.
