The use of calculated actual and potential evapotranspiration for estimating potential plant growth

Rodney J. Arkley and Rudolph Ulrich

Hilgardia, 1962, vol. 32, issue 10

Abstract: Potential evaporation, ETp, can readily be calculated from monthly mean temperatures by means of tables and nomograms now available in the literature. Actual evapotranspiration, ETa, is calculated from ETp by taking precipitation and the water-holding capacity of the soil into account. Either value can be calculated for the whole year (ETp or ETa) if frost-tolerant plants are under consideration; or for the frost-free period (ETp 32° or ETa 32°) if frost-sensitive plants are under consideration.
