Dry ashing five different plant tissues at temperatures from 400 to 700° Cat 4 and 15 hours affected the concentration of Al, B, Cu, Fe, K, and Mn found upon analysis by both emission and atomic absorption spec-troscopy. The elements Ba, Ca, Mg, Mo, P, Sr, and Zn were not affected by the varying temperatures and times. Dry ashing at 500° C for 4 or 15 hours gave results comparable to the known element concentration or that determined by wet ashing. At temperatures below and above 500° C, volitilization losses and absorption occurred.
