While swine lagoon sludge is primarily used as a source of N for receiver crops, the impact of other nutrients in the sludge on soil properties should be considered. Therefore, objectives of this study were to assess the impact of swine lagoon sludge application in corn production on (i) Mehlich‐3 extractable Zn and Cu in the soil, (ii) Zn and Cu accumulation in the crop, and (iii) Zn and Cu removal from the field in grain.
