Emission and distribution of fumigants as affected by soil moistures in three different textured soils

► A rang of soil moisture levels were tested in three different textured soils. ► Soil columns were used under well controlled moisture conditions. ► High water content reduced and delayed emission peak flux in finer-textured soils. ► The wetter soils had higher fumigant concentrations than the drier soil. ► The air-filled porosity may serve as a good indicator for estimating emissions.
