METHODS OF COMPUTING FIELD EVAPOTRANSPIRATION AND VARIATIONS OF SOIL MOISTURE

In this paper, a method of computing 10-day and Monthly potential transpiration and evapotranspiration under the condition of soil moisture deficit from climatological data are presented. Further, a method of computing critical soil moisture and coefficent of evapotranspiration from main stages for some crops has been formulcted. The error analysis of the methods and t1e reliability of calculating results are discussed.
