Fig. 7. The dust potential of the three feedlot soil mixtures (FSM) with increasing moisture content (A) and the relationship between the moisture threshold (MT) and organic matter (OM) content (B). The standard error of the least squares mean (n = 3) for dust potential (A) is 10.3. Open circles in (B) are data from four areas within a cattle feedlot pen as reported in Miller and Woodbury (2003), whereas filled circles are data points calculated from the three FSM. The term DM is dry matter.
