Hard clams provide many benefits to Florida’s coastal ecosystems beyond supporting the clam aquaculture industry. For example, one of these benefits is water quality improvement through filtration and nutrient cycling. However, both pollution and overharvesting have led to a decline in native clam populations for many areas. This has resulted in growing interest among restoration practitioners to rebuild clam populations. There are two clam species native to Florida currently used in restoration: the northern hard clam, Mercenaria mercenaria, and the southern hard clam, Mercenaria campechiensis. This publication is for academics, restoration practitioners, and policy makers interested in shellfish restoration. The goal of this document is to describe the similarities and differences between these two species. This document also serves as a resource for selecting the best hard clam for a restoration project.

The publication focuses on nitrogen (N) nutrient requirements for corn production using best management practices (BMPs) in Florida. The intended audience is corn producers, agricultural consultants, Extension agents, Extension specialists, and researchers. The aim is to provide and recommend BMPs that comply with statewide BMP guidelines, maximizing the yield and economic return while minimizing environmental N losses. The guidelines present results from multi-year, multi-site, field-based research conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The small plot research was conducted at the UF/IFAS North Florida Research and Education Center, Suwannee Valley, Live Oak, Florida (NFREC-SV). The publication includes a nutrient recommendation in terms of N required per bushel of productivity.
