| Abstract | Introductionchanges in the Everglades ecosystem are of critical concern in the development of a restoration plan for the Everglades. Stormwater runoff from the Everglades Agricultural Area (EAA) is a major source of water to the Water Conservation Areas and Everglades National Park in South Florida. However, increased concerns regarding runoff water quality from the EAA basin, specifically phosphorus (P), and its environmental impact on the Everglades wetland ecosystems led to the development of a regulatory program in the EAA that required P levels in drainage waters leaving the basin to be reduced by at least 25% relative to historic levels. Farmers of the EAA have responded to the challenge to achieve this P load reduction by implementing Best Management Practices (BMP) programs on their farms, which includes monitoring their individual farm discharge waters for flow volume and P concentration. The South Florida Water Management District has developed a BMP table that lists the BMP practices that have been designed to reduce particulate P and sediment loads in drainage waters from EAA farms. The purpose of this document is to explain and discuss these particulate P and sediment control practices. These practices serve as important tools in efforts to improve water quality in the basin. This EDIS article is one in a series that attempts to explain in easily understandable terms the implementation methods and rationale behind the main P load reducing BMPs employed on EAA farms. In watersheds draining agricultural areas, P can be transported in soluble and particulate forms. Particulate P consists of all solid phase forms, which includes P sorbed by soil particles and organic material transported during runoff. On-farm studies in the EAA by UF/IFAS research ers have shown that a significant portion of the total P load in drainage water leaving farms is in the particulate form. More recent UF/IFAS studies confirmed that particulate P accounted for 20% to 70% of the total P exported from EAA farms. Efforts targeting the reduction of particulate P and sediments in farm drainage waters are important to further reduce the total P load at the farm level. Thus, the use of any practice specifically directed to the reduction of particulate P can considerably influence the total P load leaving the farm. |
