THE DROUGHT IMPACT IN AGRICULTURAL LANDSCAPE ON SANDY AND LOAM-SANDY SOILS AND THE PROJECTION OF ADAPTATION PROCEEDING. Crops in agro ecosystems on sandy, sandy-loam and loam-sandy soils are very sensitive to changes of water content in the aeration zone. They react to decrease of water content by decrease of yields and harming of agrobiodiversity. Generally, from the physiological point of view, the drought occurs in case of lack of precipitation and high evapotranspiration. Drought as a natural phenomena is with its consequences allotted into natural disasters which influence natural ecosystems, as well as agroecosystems, and thus the biodiversity itself. The biodiversity depends on water contents in the soil aeration zone. If the dry period is prolonged and the supply of available water approaches the wilting point, the plants react by harming the ratio of photosynthesis and respiration, decrease of formation of new organic matter, decrease of turgor, wilting and even dying. However, drought impacts depend on plant, variety, stage of growth, etc. In order to decrease the drought impact in agricultural landscape. In agroecosystems intentionally managed by humans, the water content in the soil aeration zone plays a significant role. The water content significantly affects the stability of agroecosystem and agrobiodiversity. This stability is significantly damaged under condition of drought start. In order to decrease the drought impact in agricultural landscape, it is necessary to adopt combined approach based on identification of drought, evaluation of its spatial occurrence, intensity and duration, and then opitimisation of landscape structure with the help of proper biological and water management activities.
