In a 25-year-old plantation of slash pine near Olustee, Florida, a single application of 200 lb. of nitrogen and 44 lb. of phosphorus per acre increased production of herbaccous understory (primarily native bluestem grasses) to more than a ton per acre the first year, a fifefold increase. Production declined sharply the second year, and the response disappeared in the third.q
