摘要：
An alternative use of sewage sludges in agriculture is proposed to reduce the risks of heavy metal pollution. It is based on the production of liquid fertilizers enriched with humic substances by obtaining extracts from sludges with 0.1 M KH2PO4+0.2 M KOH reagent. The whole extract and fulvic acid fractioon show a remarkable hormone-like activity in durum wheat growth. Furthermore, the selected reagent is able to dehydrate sludge residues in such a way as to make their separation easier.
