Other claims from this paper (5)
- Intervention effect Sewage sludge at 30 and 40 Mg ha-1 cumulatively increased leaf P, Ca, Mg and Zn concentrations over four seasons of maize.
- Intervention effect Sewage sludge fertilization reduced maize cob diameter, cob mass and grain yield at the end of the last harvest.
- Recommendation The treated sewage sludge is a viable alternative for maize fertilization in the first harvest.
- Recommendation Treated sewage sludge can be recommended instead of NPK mineral fertilizers in built-up fertility soils.
- Intervention effect Treated sewage sludge provided maize grain yield increases in the order of 1.35 Mg ha-1 in the first harvest.
