| Abstract | ||
| Sewage sludge was treated with some Ni stabilizers including silica gel (Si), cement by- pass (CB) and iron oxide (FO) to reduce its availability in the soil, and absorption by onion plants (direct effect) in the first season and Jew's mallow plants (residual effect) in the second season. A loamy sand soil was amended only before the first season with sewage sludge treatments including 10 and 20% Si, CB and FO treated sludge as well as Si + CB, Si + FO and CB + FO treated ones. | ||
