摘要：

Removal of moisture from soil is of great importance in research, and any attempt in improving the existing soil drying techniques would be desirable. Evaporation rates of water from six soil samples of varying organic matter content were determined gravimetrically while exposed simultaneously to bipolar ions produced by corona electrodes and a thallium-204 beta-ray source. These devices produced ion fluxes of 2.63 x 1012 positive and 2.68 x 1012 negative ions cm-2 s-1 in air at the soil surface. Argon (A), dry air, and nitrogen (N) gases were used as ionization media for moisture loss studies. The rate of moisture loss was found to be the lowest in N. The water vapour fluxes from the exposed soil samples were enhanced by a factor of at least three compared to control samples under ambient conditions. © 1990, Taylor & Francis Group, LLC.
