Soil science 1300-OLBZ401
Lecture:
terms in the field of soil science; definition of soil, subject and development of soil science; conditions of formation of different type of soils (soil forming factors, pedogenesis, processes in soil profile, time as a factor having an influence on evolution of soil, relationships between properties of soils and climate, relationships between properties of soils and flora); morphological features of soils and principle of their description (characteristic of soil profile, soil horizons, thickness, colours, structure and texture, porosity, admixture); soils as a system of three phases (characteristic of mineral composition of soils, characteristic of organic matter, origin and evolution of organic matter, mineral-organic complexes, water in soils, chemical composition of soil solution, water capacity, soil aeration, respiration capacity of soils, chemical composition of soil air, exchange of soil air with atmospheric air, thermal relationships); physical properties (density, conciseness, plasticity); physico-chemical properties of soil (characteristic of microelements, and makroelements, sorption capacities, soil pH effects, buffering properties); soil fertility, reserve of soil components; soil fauna; degradation of soils; factors of soil degradations; genetic classification of polish soils, European and FAO/WRB classification of soils, Soil types by clay, silt and sand composition; geography of soils; cycles of soil evolution; old soils – paleopedology;
