Mitigation of heavy metal bioavailability and uptake by fodder crops using organic and mineral amendments in a sewage-irrigated peri-urban agroecosystem
Long-term irrigation with sewage wastewater can increase the bioavailability of potentially toxic metals in peri-urban soils and promote their entry into fodder-livestock systems. This greenhouse study evaluated six amendments namely biochar, bentonite, zeolite, humic acid, vermicompost and farmyard manure (FYM), for r...
