Estimate of the resistance to water vapor transport in soybean crop

Abstract

Micrometeorological data obtained on a soybean crop was used to estimate the crop and the aerodynamic resistances to water vapor transport using the energy balance concept. The aerodynamic resistance to water vapor transport was about 10 s/m from 9:00 A.M. to 4:00 P.M. and the crop resistance varied from 50 to 100 s/m during periods of higher net radiation.
