mospheric air pressure and sieving them in water, using the procedure by Kemper and Rosenau (1985). The percent of the soil particles smaller than 0.25 mm which do not go through that size screen during the sieving is the aggregate stability in Fig. 2. Water retention was determined on duplicate soil samples from 1 to 1500 kPa using pressure-extraction cells. Air-dry samples of
