Abstract

Shrinkage and cracking characteristics at two sites under border strip irrigation were examined. At one site, irrigation water salinity was varied. Image analysis of soil surface photographs was used to quantify surface ped geometry. There was no spatial dependence for water content and bulk density at the scale of several centimeters or between peds. Larger, more polygonal peds were observed in higher salinity treatments, wheel traffic rows, and after repeated irrigations. Surface shrinkage increased with salinity. Dry bulk density was higher on the high salinity treatment both on the surface and with depth. Perimeters of the 9000 ppm treatment peds were less than perimeters for other treatments. Surface percent crack area followed percent change in bulk density. -from Authors
