Abstract:

Wind erosion causes numerous damages to agricultural land, including reduced sustainability, soil degradation, and less crop production. Fortunately, there are also a number of ways to reduce wind erosion, including wind barriers, modified agricultural practices, and type of vegetation cover. The aim of this work is to suggest a wind erosion model using geographic information systems which could be used by people with any level of education and experience with the application. The suggested wind erosion model is tested using two scenarios on the same agricultural field near the village Znojmo during the year 2023. The first scenario simulates the field with corn planted and grown during the approximate growing season, and the second simulates the field left bare for a year. Planting corn produced maximum transport capacity values in a range from 17,683 to 53,712.9 kg/m. Keeping the soil bare produced larger values of maximum transport capacity in a range from 17,980.9 to 54,617.9 kg/m in the area of the agricultural field. Total soil loss for the field during the year was 51,384,969 kg with corn, and 52,249,892 kg with bare soil, or 406.29 and 413.13 tons/hectare/year respectively.
