Responses to Chopping and Rock Phosphate on South Florida Ranges

Abstract

Native plants growing on phosphorus-deficient soils in south Florida responded favorably to cross-chopping and fertilizing with ground rock phosphate. Availability of soil phosphate remained high throughout the 5-year study. Chopping effectively controlled saw palmetto and reduced the density of pineland threeawn, while increasing herbage yields, availability, and utilization. Rock phosphate increased herbage yields, raised nutrient levels, and improved palatability of most native plants. These practices offer practical opportunities for improving Florida rangelands.
