Soil crusts are the result of aggregate breakdown and compaction due to raindrop impact and physicochemical dispersion of scaly particles at the soil surface. The properties of artificially formed crusts have usually been studied on two widely different scales: (i) the whole crusted area on which infiltrability was measured and (ii) small samples of crust as used for scanning electron microscope (SEM) studies. The surface characteristics of artificially formed crusts of a Plinthustalf with two levels of exchangeable sodium percentage (ESP) were investigated on three different scales viz. (i) macro: the whole crusted area as used for bulk infiltration measurements (500 mm by 300 mm), (ii) intermediate: having the typical dimensions of mounds (8-10 mm in diam. where local permeabilities were determined), and (iii) micro: having the dimensions of samples used in SEM studies.
