Basic aims:  The objective of the course is the knowledge of the main characteristics of the soil, and its principal functions agronomic aspects related to its vulnerability in relation to different uses and its classification.
Acquired skills:  Knowledge of the chemical, physical and biological properties of soil, their interactions with plants and environment and the soil classification.
Course contents:  Soil definitions. Mineral and rocks. Processes of alteration of the mineral. Products of the alteration: the
clays. Physical properties of soil. Soil organic matter. Soil chemical properties: mechanism of cationic and
anionic exchange. Soil and water, soil and air. Red-ox potential of soil. Soil pH: acidity, salinity, paddy soils.
Soil fertility: nitrogen, phosphorus, sulphur and other meso-elements cycles. The fertilizers: fertilizers and
amendments. The use of sludges and manures: principals agronomic and environmental aspects. Soil Taxonomy. Land Capability Classification. Soil
analyses (laboratory).
Program:  Definition of the soil: the soil as open system. The soil main functions: production function, protective,
natural function. Soil as a three-phase system: solid, liquid and gaseous. Theoretical structure of a soil
profile. Minerals and rocks: mineral silicates, classification and structure of silicate minerals. Processes of
minerals alteration: disintegration and decay, action of water, wind, glaciers and biotic entities. Products of
alteration: clays. Structure of the clay: 1:1 clays, 2:1 clays, heterovalent isomorphous substitutions. The
physical properties of the soil: real and apparent texture, structure, density and porosity. The organic
matter: humic and non humic component, processes of accumulation and consumption in relation to soil
fertility. Action of the substance on the chemical, physical and biological properties of the soil. Chemical
properties of the soil: adsorption and exchange: main theories, the characteristics and composition of the
exchange complex of the soil, degree of base saturation, cation adsorption and anion specific and
non-specific, complex inner-sphere and outer-sphere. The soil-water relationships. The soil-air relations:
soil as a "respiratory system". Red-ox potential of the soil. Chemical properties of soil: different pH values
(in water and potential). Acid, basic, sodium, submerged soils. Soils with extreme pH: possible correction.
Soil fertility. Nitrogen cycle. The phosphorus cycle. Sulfur cycle and other meso and micro elements in
relation to the availability in the soil. Fertilizers: mineral, organic, amendments and corrective. The use of
sludges and manures: principals agronomic and environmental aspects. Soil Taxonomy. Land Capability Classification. Soil analyses (laboratory).
