Distribution of heavy metals in maize and mudflat saline soil amended by sewage sludge

Sewage sludge has been considered as the economic choice for soil amendment. However, whether sewage sludge can effectively amend mudflat saline soil remains unclear. This paper was one of first studies to fill this knowledge gap by assessing the persistent effects of one-time application of sewage sludge on distribution of heavy metals in maize (Zea mays L.) grown in mudflat saline soil.
