Abstract

Soil aggregates ranging from 0.5 to 9.5 mm. in diameter from Nicollet silt loam were used to study the effect of aggregate size on soil moisture retention. It was concluded that (a) between suctions of 0.10 and 1.0 bar, the gravimetric percent moisture retained by various sized aggregates was in the following order: 0.5 < 1.0 < 2.0 ≤ 3.0 ≤ 5.0 ≤ 9.5 mm.; (b) between suctions of 1.0 and 5.0 bars, the gravimetric percent moisture retained was in the following order: 0.5 < 1.0 ≤ 2.0 ≤ 3.0 ≤ 5.0 ≤ 9.5 mm.; and (c) at suction of 10 and 15 bars, the moisture retained by aggregates of various sizes was essentially the same.
