Wisconsin lawmakers have reintroduced a bill to ban lawn fertilizer with phosphorus.

The bill's authors say phosphorus pollutes state waters. Under the bipartisan measure, no one could apply fertilizer with phosphorus to lawns, golf courses and other mowed grass. It could be used on first-year lawns or if tests show soil has little phosphorus.

An identical bill died in the Assembly last session.

Brian Swingle is the executive director of the Wisconsin Green Industry Federation, which represents professional fertilizer users, such as landscapers. The federation opposed the bill last time.

Swingle says the bill also would prohibit retailers from displaying fertilizer with phosphorus, making it difficult for first-time lawn growers to find. He also says lawn fertilizer contributes little to phosphorus pollution.
