- Intervention effect Leaf dry weight of soybean was reduced curvilinearly across soil Zn additions at each pH.
- Intervention effect Leaf yield increased at the lower soil Zn treatments.
- Intervention effect Root dry weight of soybean was unaffected by Zn additions at the lower pH.
- Observation Leaf dry weight yields differed significantly among soybean cultivars at the higher Zn treatments.
- Association Root Zn contents of soybean increased linearly with increasing soil Zn at each pH.
- Association Leaf Zn contents of soybean increased linearly with increasing soil Zn at each pH.
- Association Soil pH strongly influenced plant Zn contents of soybean.
- Association Hudson Manchu soybean absorbed more Zn than the other cultivars at both pH levels.
- Association Hudson Manchu soybean translocated less Zn than the other cultivars at both pH levels.
- Association A 20% leaf yield reduction corresponded to leaf Zn contents greater than 620 ppm at both pH levels.
- Observation Hudson Manchu had only 370 ppm Zn in its leaves at a 20% yield reduction at pH 6.5.
- Association Root Mn of soybean increased linearly with soil Zn additions at both pH levels.
- Association Leaf Mn increases of soybean were curvilinear at pH 5.5 and linear at pH 6.5.
- Observation Leaf Mn concentrations of soybean reached reported toxic levels at both pH levels.
- Intervention effect Extractable Mn in soil was unaffected by soil Zn additions at both pH levels.
- Intervention effect Foliar Fe of soybean decreased with increasing soil Zn at pH 5.5 and 6.5 without approaching deficiency levels.
- Intervention effect Foliar P of soybean decreased with increasing soil Zn at pH 6.5.
- Observation Zn-tolerant and Zn-sensitive soybean cultivars had similar foliar Fe and P amounts.
