Realized in the conditions of the Republic of Belarus studies showed that management of cultural landscapes should be based on the models which make it possible to present a proper evaluation of yielding capacity of different types of agricultural lands taking into consideration land quality and influence of natural and climatic factors. Dynamics of yielding capacity of green mass and application of mineral fertilizers at the natural and improved haylands of Belarusian Poozerye region was analyzed. There was noted a determinate variation of grass yields at pasture lands and plowing lands in various years. The presented mopdels made it possible to calculate the average yielding capacity of grasses cultivated at pasture lands and plowing lands in any year, as well as to forecast the extent of risk of yield capacity taking into account yield variability in different years. It was proposed to plan the production volumes of fodders for animal husbandry branch taking into account the variability of yielding capacity at various years under the influence of various unregulated natural and climatic conditions

In course of the realized investigation there was analyzed the dynamics of climatic resources of Belarusian Poozerye region (the Republic of Belarus) over the last 25 years. In course of he study there was analyzed the amount of effective yearly average temperatures of cultural landscapes of Belarusian Poozerye over 1998-2008. Also, there was presented the yearly average depth of precipitation in the analyzed area over 1984-2008. Results of 25-year studies over the climatic resources resulted the following: possibility of solution of a problem of plant productivity by means of concordance of physiological requirements of agricultural crops and the potential possibilities of cultural landscapes; notable increase of agroclimatic resources (increasing of amounts of active and effective yearly average temperatures; duration of vegetation period, etc.) requires the appropriate adaptation of cultivated agricultural crops; displacement of the northern border of the central agroclimatic region (isothermal curve 2000) to the north of the Belarusian Poozerye requires development of new approaches to management of this region; changes of growing conditions of agricultural crops requires specification of the existing technologies, scientific approaches to the specialization of the territory.
