Description
  • Areas the most susceptible to wind erosion were chosen for the comparison of potential and real erodibility of soil by wind. All the areas are located in the Southern Moravia, the south-east of the Czech Republic. Ambulatory measurements of parameters required for wind erodibility determination were done during 2006 in three districts that are heavily endangered by wind erosion (districts of Breclav, Znojmo and Uherske Hradiste). Potential and real erodibility by wind was determined from wind velocity, soil humidity, content of clay and non-erodible soil particles. Potential soil loss does not go over the limit of the tolerable amount of soil loss 10 t.ha-1.year-1 at any studied area, even though all the three areas belong to the ones strongly susceptible to wind erosion. On the other hand, the tolerable soil loss for real erodibility 1.4 g.m-2 was exceeded at two regions. Non-objectivity in the erodibility evaluation of heavy clay soils follows out of the results, as so as evident necessity of new kn

  • Ke srovnání potenciální a skutečné erodovatelnosti půdy větrem byly vybrány lokality, které splňují základní předpoklady vzniku větrné eroze a větrná eroze byla na těchto lokalitách skutečně prokázána. Všechny lokality se nachází na území jižní Moravy -- v okresech Břeclav, Znojmo a Uherské Hradiště. Během roku 2006 probíhala na těchto lokalitách ambulantní měření parametrů potřebných ke stanovení erodovatelnosti půdy větrem (rychlost větru, vlhkost půdy, obsah jílnatých a neerodovatelných částic v půdě). Byla stanovena a porovnána erodovatelnost půdy potenciální a skutečná (aktuální), vycházející z naměřených okamžitých dat přímo v terénu. Potenciální odnos půdy větrem nepřesahoval ani na jedné lokalitě přípustnou mez 10 t.ha-1.rok-1, a to i přesto, že všechny tři lokality jsou řazeny do oblastí silně ohrožených větrnou erozí. Oproti tomu skutečná erodovatelnost půdy větrem 1,4 g.m-2 byla překročena na dvou lokalitách. Z výsledků vyplývá neobjektivnost hodnocení ohroženosti půd těžkých a zřejmá potře (cs)
