Figure 1.

Changes in seed Fe concentration ([Fe]) and Zn concentration ([Zn]), content, and removal in response to added fertilizer N in soybean varieties that are resistant, moderately resistant, and susceptible to Fe deficiency. R (closed circles), Fe efficient and resistant to Fe deficiency chlorosis; MR (open circles), moderately Fe efficient and moderately resistant to Fe deficiency chlorosis; Susc (closed squares), Fe inefficient and susceptible to Fe deficiency.

Changes in seed Mn concentration ([Mn]) and N concentration ([N]), content, and removal in response to added fertilizer N in soybean varieties that are resistant, moderately resistant, and susceptible to Fe deficiency. R (closed circles), Fe efficient and resistant to Fe deficiency chlorosis; MR (open circles), moderately Fe efficient and moderately resistant to Fe deficiency chlorosis; Susc (closed squares), Fe inefficient and susceptible to Fe deficiency.
