The effect of soil structure on the hydraulic characteristics of the soil
 Čermák, Petr ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Soil is very important in the hydrological cycle of landscape. The retention and storage ability depends on the quality, type of structure and other properties of the soil. The retention ability of soil is determined by gravitational pores (the coarsest pores), which are drained off after filling the water. The accumulation depends on the capillary pores in which water is bounded by capillary forces. The soil works also as a filter´s environment which cleans naturally the water. This process can be also converse, when various substances are released from soil to water. The state and amount of water between the surface of soil and level of groundwater affect many important processes such as fertility of soil, drain from drainage area, supply of groundwater sources and others. Structure of soil changes fundamentally by cultivation of soil and types of farming crops. Aggregates are mechanical destructed by weather conditions and soil gradually loses its good qualities, fertility is reducing and flood protection is decreasing. This fact can be avoided by right choice of crops and the type of tillage soil.
