D. aBare evaporation near a surface poin-source emitter. c1986 aTwo field studies were conducted to estimate bare soil evaporation for 7 days following surface trickle irrigation from a point-source emitter. A microlysimeter method and an infrared thermometer method were used to estimate evaporation at several sites within both wetted dand non-wetted areas surrounding the emitter. Based on data from both methods, evaporation accounted for about 33-40% of the applied waterin bothestudies. Where the soil was wet, the microlysimeter method tended to estimate higher values than the infrared thermometer method. For dry soil conditions the infrared thermometer method estimates were higher. Agreement between the two methods was good for cumulative 7-day total evaporation estimates in both studies. asoil awater aÁgua aSolo aUmidade aInfrared aInfravermelho aMicrolisimeter aMicrolisimetro aMoisture aTermometria aThermometry1 aSALEHI, R.
