3.4.8 Modelling of Hydrometeorological Regime of Vegetative Cover
Agricultural plants are in complex interaction with the environment. The Soil-Plant-Atmosphere system requires permanent support from external sources which are partly man-regulated. So this is the task of agroecology to conduct a research into flows of energy and matter in this system, physical and chemical conversions and biological transformations of mineral and organic compounds. Existence of agroecosystems presupposes purposive anthropogenic activity. It is possible to apprehend the mechanisms of conversions and biological transformations in the system and the anthropogenic influence by the instrumentality of mathematical modelling. It is also used as a means of agroecosystem management.

The course is intended to provide the studies of mathematical modelling of hydrometeorological regime in vital environment of the cultivated plants and the processes of energy and mass transfer in the topsoil.
