Collaborative Planning for the Future of Water Resources in Central Florida: Central Florida Water Initiative

suburban landscape

Rules and regulations that govern our use of natural resources, specifically water, are changing. Over the past 80 years, Florida’s population increased four times, from approximately 5 million to more than 20 million people. With this population increase, water needs have also increased. Forward-looking communities think about the future of their towns, counties, or the state as they work on redefining regulations to meet future water needs without harming our springs, lakes, rivers, and estuaries. This 4-page fact sheet written by James Fletcher and Tatiana Borisova and published by the Food and Resource Economics Department discusses the Central Florida Water Initiative, which deals with advancing water-use and water-resource-protection strategies for Orlando and its vicinity.

Reframing Leadership

Effective leadership is essential in the businesses where we work, the institutions where we learn and in the communities where we live. Our own leadership is a product of how we see the world. This three-page article looks at Bolman and Deal’s book Reframing Organizations and the different frames to address organizational issues and leadership. Written by Matthew Sowcik, Hannah Carter, and Valerie McKee and published by the Department of Agricultural Education and Communication.

Herbicide Residues in Manure, Compost, or Hay

Compost bin.

When purchasing compost, it is important to understand that some manure-based products can contain herbicide residues that can affect the growth of certain plants. Manure from animals that have been fed forage treated with aminopyralid or other closely related herbicides, such as clopyralid or picloram, can be contaminated with these herbicides, which severely restrict the growth of legume and solanaceous crops and other broadleaf plants. This 3-page fact sheet discusses aminopyralid, compost, questions to ask when purchasing bulk compost or mulch, conducting a bioassay, aminopyralid injury symptoms, and steps to consider if contaminated manure or compost has been added to a garden or field site. Written by Jason Ferrell, Peter Dittmar, and Brent Sellers, and published by the UF Agronomy Department, May 2017.

A Beginner's Guide to Water Management?Muck: Causes and Corrective Actions

Muck from pond at Fisheries and Aquatic Sciences

Muck is both the popular and the scientific term for the material found on the bottom of ponds and lakes. Its “oozy” feel and rotten egg smell can be offensive, and it provides habitat for problem insects like blind midges. It may seem simple: get rid of the muck; get rid of the problems. However, there is more to this muck-raking story. Excessive amounts of muck in the wrong places certainly can cause problems, but just enough muck in the right places is essential for a healthy lake that supports diverse wildlife and fishing. Learn all about muck and what to do about it in this 13-page fact sheet written by Mark V. Hoyer, Daniel E. Canfield Jr. and Mark Brenner and published by the School of Forest Resources and Conservation Program in Fisheries and Aquatic Sciences.

Managing the Health and Productivity of HLB-Affected Groves

Citrus groves around Lake Alfred, Florida. Oranges, fruit, trees.

After years of extensive research from across the world, we still do not have a cure for HLB; however, we have learned a lot about this disease, the plant’s response to the disease, and the disease vector. Based on scientific and observational information gathered in the last decade, a number of tools and strategies are currently available for growers to maintain the health and productivity of HLB-affected trees. This four-page fact sheet will shed light on these currently available horticultural inputs and practices that can be implemented immediately by growers to maintain and improve citrus tree health.Written by Tripti Vashisth and published by the Horticultural Sciences Department.

Worker Protection Standard: Respirators

Figure 5. Respirator use must conform to OSHA standards in the revised WPS.

On November 2, 2015, the EPA revised the WPS, making significant changes to the rule?s requirements. Most of the revised provisions became effective January 2, 2017; there are four provisions that are delayed until January 2, 2018.

Florida Fertilizer Usage Statistics

Nutrient applications are often required to meet Florida’s demand for agricultural and horticultural commodities, but often those applications occur in close proximity to water bodies. In order for scientists, policy makers, and citizens to make decisions regarding nutrient issues in Florida, it is important to first understand which markets contribute to Florida’s fertilizer consumption. This three-page fact sheet explains Florida’s fertilizer usage statistics. Written by T.W.Shaddox and published by the Environmental Horticulture Department.
