Analysis of Soil Aggregate Degradation in Eavy Soils Situated in Localities at Risk of Wind Erosion

Original language description

We present the results of our study of wind erosion in heavy soils. The areas that are at highest risk of wind erosion usually display light soils; however, in some localities with the occurrence of heavy soils, wind erosion may also be observed in particular meteorological conditions. The meteorological conditions in winter seasons induce degradation of soil aggregates. This degradation in mainly effected by the action of water and subsequent freezing/thawing of the soil surface. Due to the pressure of freezing water in the soil and its subsequent resolution, the soil aggregates are degraded to erodible fractions, with a possible erosion event in the case of erosion-effective wind. The quality of agricultural land fund in the Czech Republic is assessed via a valuation system based on the ecological-productive land evaluation. This system was established in the 1960-1980s after a complex survey of agricultural land. It provided integral information on the agricultural land quality and on the price of agricultural land parcels derived from their productive capacity. Starting from the 1990s, evidence in the database of Evaluated Soil-Ecological Units (ESEU) has been regularly updated. To analyse the susceptibility of heavy soils to wind erosion we used the database of ESEU and selected soil types according to the main soil unit (further referred to as MSU) - 06, 07, 20, 61, 63, and 57. The studied area is situated in the surroundings region of South Moravia (Czech Republic), where all the above-mentioned MSU can be found. In all cases, soil samples were collected at the beginning and end of winter. After collection, the soil samples were analysed for aggregates and the proportion of erodible and non-erodible fractions was determined. Climatic data on the temperature of soil surface and condition of soil moisture were obtained from the nearest professional station of the Czech Hydrometeorological Institute (CHMI).
