Effect of plot length on soil loss and runoff in vineyards

Popis výsledku v původním jazyce

Soil erosion is a threat to natural ecosystems, especially when the erosion rate is highly exceeting the creation of a new soil from a parent material. The erosion process is a phenomenon that is studied by many research teams around the world. Various devices are used to observe the soil loss process and a rainfall simulator is one of the common tools for conducting experiments in which the main characteristics of surface runoff and soil loss are measured. Teams of researchers are using rainfall simulators with various plot dimensions, rainfall intensities, and kinetic energies. This contribution focuses on the comparison of the different lengths of the experimental plot in vineyards. Experimental plots of length 1 m were compared to plots of length 8 m, all of them in width 1 m. The experiments were carried out on plots cultivated with vineyards in the Moravia region of the Czech Republic. The results showed that the runoff was approximately 30 % higher on the small plot, but the soil loss was approximately 1,5 times higher for the large plot. The small rainfall simulator is a good tool for monitoring the initial stages of the surface runoff and erosion process, but to better understand the soil erosion rate it is beneficial to conduct experiments on longer plots. This research was supported by projects Technology Agency of the Czech Republic by TJ02000234, Ministry of Agriculture of the Czech Republic QK1810341, QK1910029, and by the Grant Agency of the Czech Technical University in Prague within the framework of grant number SGS 20/156/OHK1/3T/11.
