Could anyone offer insight on the physiology of iron (or other similar nutrient) chlorosis?
Specifically, why would a Pin Oak suffer the nutritional deficiency leading to chlorosis, and a Red Oak (or other species), growing in similar soil nearby, remain healthy? I do understand that higher pH relates to soil iron chemistry and subsequent uptake. But...why are two trees, both facing that constraint, reacting so differently? Any insight appreciated... --Paul Weihe ------------------------------------------------------------------------ -- Paul Weihe, Ph.D. Associate Professor-Biology & Environmental Science Central College - Biology Dept.
