Establishment of corn crop stands by soil protection technology on land fealds withs slightly soil erosion condition

The work is based on the needs of farmers who grow corn for cattle feed and biogas plant. For many farms corn is a strategic crop. But i tis also an erosion crop and therefore it is necessary to pay attention the erosion. The experiment is set in terms of ZD Krasna Hora nad Vltavou. The firm manages on mildly and severely threatened soil by erosion and there comes a potential problem with water soil erosion too. It is tested 3 soil conservation technologies with different spreads rows and different crop density. It is monitored the effectiveness of various anti-erosion technologies, stand density and row spacing. Measurement is managed by Research Institute of Soil and Water Conservation. The yield of individual parcels was evaluated. The biomass yield and grain were determined
