The Study of the Heat and Moisture Balance of the Ukraine as a Basis for Measures to Raise the Productivity of Agriculture

The paper discusses the availability of data for calculating the heat balance and the moisture balance for the territory of the Ukraine. The problem of determining total evaporation, evaporation from the surface of the soil and transpiration of agricultural crops is treated in detail. The authors discuss practical applications of heat and moisture balance work, including the setting of irrigation norms, the study of the regimes of stream reservoirs, swamp drainage and the study of the effect of tree plantings on the microclimate of sheltered fields.
