“The growers’ main interest is not having to dispose of it,” he says. “Remove the drip tape and rototill, then drive away and you’re done.”
Despite interest in alternative mulches, George McManus III, owner of L.H. Piggott & Girls Inc., in Benton Harbor, Mich., has stuck with black plastic as the most cost-effective option to warm fields for a longer growing season.
