Some ecoenergetic aspects of the grey-meadow soils and agrophytocenosis under the Salyan plain condition of Azerbaijan

Depending on water-physical characters of the grey-meadow soils in Salyan plain possessing arid climatic condition of Azerbaijan, the temperature and water regime has been analyzed in the article. The productivity of the barley, lucerne and cotton plants was investigated from the soil formation energetics standpoint, an energy balance was compiled, a radiation balance and plants utilization from the sun energy was quantitatively evaluated. The multinomial and separately two-nominal relation dependence was obtained among the plant productivity, radiation balance and soil humidity.
