The fertilizing effect of P in different sewage sludges was investigated in a pot experiment. Five different sludge types were applied to rye grass growing in either a moraine or a clay soil. The flocculating agents used to precipitate P in the sludges were aluminium chemicals, iron chloride or biol...
