It might seem an unusual ingredient for plant fertilizer, but metal dust from spent household batteries are being tested as potential crop nutrient supplements by an Australian recycler and supplier of battery materials.

After collecting recycled everyday alkaline batteries from local pick-up points around the country and then shredding them, Lithium Australia NL, conducted short-term trials by testing the dust -- containing valuable trace element nutrients such as zinc and manganese -- on pots of wheat in glasshouses.
