EXTREME SOIL MOISTURE REGIME AS LIMITING FACTOR OF THE PLANT'S WATER UPTAKE

According to meteorological/hydrological/ecological forecasts the risk probability, frequency, duration and intensity of extreme environmental events and soil moisture situations will increase in the future. Hungary - as tire deepest part of the hydrogeologically practically closed Carpathian Basin - is particularly sensitive and vulnerable against these stresses which may result in serious problems in the water (and nutrient) uptake of plants. Under such conditions the efficient use of soils as tire largest potential natural water reservoir has special significance. Water stored in soil in plant available form may ensure the "normal" water (and water-soluble nutrient) supply of the natural vegetation and cultivated crops.
