摘要
In a field trial with four variants of cultural practices in maize for silage cumulative surface runoff and soil loss were measured under artificial rainfall generated by a rainfall simulator. Measurements in June 2015 showed that water infiltration into the soil in a maize stand on ploughed land was markedly lower than in variants with soil tillage for maize without ploughing. The highest soil loss at surface water runoff in June was found out in variants of maize cultivation with ploughing. The results of measurement of water intake by the soil and soil loss due to the flow of water in the period of the events of intensive rainfall in storms indicated that maize cultivation with ploughing is a risky practice compared to soil tillage without ploughing.
