Use of microlysimeters to measure evaporation from sandy soils

摘要: Evaporation from soil can be a major component of crop water balance and land surface energy balance. A number different applications the microlysimeter method to measure evaporation have been used in recent studies. Microlysimeters were extensively three sandy soils for this study. Measurement microlysimeters with dimensions ages allows discussion sources error inherent method. The recorded diameters 214 mm, 152 mm 51 was not significantly different. comparison 100 200 deep showed that depth had no significant influence during first 2 days after extraction profile. For periods beginning or more rain, differences owing may occur up 7 days. Soil cores extracted at times immediately following rain event, thereafter. This period difference extended about 4 when within (i.e. root field significant). protocol use is developed these results.
