Influence of primary tillage on the displacement of soil particlesOriginal Paper

The loss of soil particles due to erosion is one of the main problems of current agriculture. However, soil tillage may also contribute to the undesirable transport of soil particles. It is to note that the effects of particular working elements used on implements for soil tillage have not been described in a sufficient way. To determine the translocation of soil particles, measurements were done in the Central Bohemian region. Two basic machines for soil tillage were used for measurements: a disc harrow and a tine cultivator. Measurements were performed on sandy-loamy Cambisol after the harvest of a spring cereal crop. White limestone grit was used for the indication of soil particle translocation. Great translocation of soil particles was observed after soil tillage with a tine cultivator ‒ the most distant particles were found out at a distance of more than 1.50 m from the original location. After soil tillage with disc harrows, the most distant particles were found out at a distance of 0.90 m. The dependence of tracer weight on a distance from the original location could be described for disc harrows and tine cultivator by an exponential function.
