streszczenie
Water vapour adsorption by soil aggregates of humus accumulating soil horizon (fractions Ł0.1, 0.1-0.25, …, 5-10 , >10 mm) is found to be adequately described in the range of 0.1Ł p/p0 Ł0.98 by the equation W = Wmh[(p/p0)6-(p/p0)3 + (p/p0)]+Wres, where: Wmh – maximum hygroscopic moisture, Wres – residual water content or model fitting coefficient. The main parameter Wmh of the dependence W=f(p/p0) of aggregated part of soil is determined by soil type.
