- Intervention effect Sewage sludge did not affect soil fertility except potassium in Typic Eutrorthox.
- Intervention effect Sewage sludge did not affect maize grain production.
- Mechanism The authors attributed the lack of soil fertility and production effects to water deficit.
- Intervention effect A 10 t ha -1 sewage sludge dose increased potassium in Typic Eutrorthox.
- Observation Base saturation in every treatment was below the 70% recommendation for maize.
