Plant Essential Nutrients and Their Role

Program Area: Plant Systems

The purpose of this publication is to inform Extension agents, consultants, and farmers about plant essential nutrients, benefits, and deficiency symptoms. This publication provides a whole plant picture with deficiency symptoms for each nutrient and the location of those symptoms on the plant. Written by Lakesh K. Sharma, J. Mabry McCray, and Kelly Morgan, and published by the UF/IFAS Agronomy Department, May 2022.

Zoysiagrass for Florida Lawns

Program Area: ==Agriculture/Horticulture==

Zoysiagrasses were introduced into the United States from Asia and provide attractive turf throughout much of the United States. In recent years, newer cultivars of zoysiagrass have entered the market with improved insect resistance, accelerated establishment, and better overall performance. This 8-page major revision of the Environmental Horticulture Department was written by J. Bryan Unruh, Marco Schiavon, Alex J. Lindsey, Kevin E. Kenworthy, and L. E. Trenholm.

Artificial Reefs in Florida 101 – effects on fish: Part 2 of an Artificial Reef series

Program Area: Informed community decision-making

Increasingly, coastal managers are placing artificial reefs in marine waters. These long-lasting habitat alterations have measurable effects on fish, fishers, divers, fisheries, and marine social ecological systems. Understanding how artificial reefs function is necessary to make good decisions about future artificial reefs. Scientific research on many aspects of artificial reefs is not always summarized and explained. In response to this need, we designed a 4-part series called Artificial Reefs 101. This publication, part 2 of the Artificial Reefs series, explains how artificial reefs affect fish populations. It will help the interested public understand more about the ecological effects of artificial reefs and provide detailed information to stakeholders including management agencies, local governments, artificial reef manufacturers, and Extension agents, to allow for better-informed decisions about building and managing artificial reefs.

Spawning Potential Ratio: A Key Metric for Managing Florida’s Fisheries

Program Area: ==Natural Resources==

From red drum to red snapper, many of Florida’s fisheries are managed with specific consideration given to a quantity called the Spawning Potential Ratio (SPR). This conspicuous acronym is an important metric to fisheries biologists and managers. It helps determine harvest size limits for fisheries and drives regulations for both commercial and recreational fisheries. However, SPR is not especially intuitive to the general public or even agency personnel and Extension agents. This publication is intended to describe what SPR is and explain how and why it is used in managing fish stocks. We think it will help people better understand fisheries management decisions, the documents describing them, and the science behind them.
