Fig. 6. Effect of sample moisture and organic matter (OM) content on dust potential from the four feedlot samples. Moisture and OM at the time of sample collection are indicated in Table 1. Values of the maximum dust potential and moisture threshold (MT; the moisture at which dust potential is half of the maximum dust potential) were calculated using regression Eq. [1]. The SE of the least squares mean (n = 3) for dust potential is 13.8. Inset figure shows the relationship between OM content and MT. The 95% confidence interval for MT varied from ±2.04 to 2.65 g H2O kg-1 dry matter (DM) for the range of samples tested.
