The project is devoted to the evaluation of the soil-plant system important agrobiological criteria, characterizing the productivity of the pastures with different degrees of grazing, and creation mathematical models expressing the available link between the parameters studied. The project is devoted to the evaluation of the soil-plant system important agrobiological criteria, characterizing the productivity of the pastures with different degrees of grazing, and creation mathematical models expressing the available link between the parameters studied. Field and laboratory studies are designed to assess the level of plants and soils parameters, including the productivity, bareness of pastures, the content of nitrogen, phosphorus, potassium, humus, pH, moisture, photosynthetic pigments and leaf surface. Laboratory analysis will be carried out in accordance with the International Standard (GOST, ISO) and the Standard Operational Procedure developed in the CENS of NAS RA. Mathematical modeling will allow to select key parameters and secure small dimension of the equation modeling system and predict the level of ecosystem productivity and the range of variation in agreement with the possible changes in the values of selected criteria.
