- Association Soybean shoot metal concentrations varied by sludge type, rate, and soil pH.
- Intervention effect Low-metal limed sludges produced metal uptake similar to controls.
- Intervention effect Unlimed high-metal sludges increased soybean metal uptake.
- Intervention effect Digested sludge linearly increased shoot Zn concentration.
- Intervention effect Digested sludge linearly increased shoot Cd concentration.
- Intervention effect Digested sludge linearly increased shoot Cu and Ni concentrations.
- Intervention effect At 112 Mg ha −1, sludge increased soybean Zn from 24 to 165 mg kg −1.
- Intervention effect At 112 Mg ha −1, sludge increased soybean Cd from 0.06 to 0.25 mg kg −1.
- Association Shoot Zn and Cd concentrations had significant linear and quadratic relationships with heat-treated and Nu-Earth sludge rates.
- Association Shoot Zn and Cd accumulation responded more strongly to sludge rate at low soil pH.
- Association At 100 Mg ha −1 Nu-Earth sludge, soybean Zn was 59 mg kg −1 at pH 6.4 and 84 mg kg −1 at pH 5.8.
- Association At 100 Mg ha −1 Nu-Earth sludge, soybean Cd was 1.75 mg kg −1 at pH 6.4 and 2.54 mg kg −1 at pH 5.8.
