Abstract

Levels as high as 53 mg DTPA-extractable Zn-kg-1 soil have been observed ln samples taken from golf course greens in Iowa. Soil test lab reports that accompany these results state that this is an excessive level of Zn for creeping bentgrass (Agrostis palustris Heds.). Interpretations of Zn test results vary greatly among laboratories and there is little information in the literature on which to base these interpretations.
