Environmental risks from applying sewage sludge compost as an organic fertilizer to clay soils [electronic resource].

Includes references.

A greenhouse crop experiment was conducted to identify the environmental consequences of applying compost as an organic fertilizer at different amounts and methods of application to a clay soil. The tested factor was the fate of heavy metals in terms of plant uptake, total recovery and accumulation in the soil surface layer. The results showed that compost application significantly increased the concentration of heavy metals in tomato fruits compared to the control.
