Health Benefits and Medicinal Value of Honey

Figure 2. HoneyHoney has been used for medicinal purposes for thousands of years. It is rich in sugars such as glucose and fructose, but it also contains small amounts of vitamins, minerals, amino acids, and antioxidants such as phenolic acids and flavonoids. These nutrients help to make honey a unique, natural health product. Its market niche as a health product is growing, and current research supports the potential of honey as a medicinal product. This 3-page fact sheet describes health aspects of honey deriving from the floral source and color, beneficial compounds, anti-microbial properties and anti-inflammatory properties. Written by Sara Marshall, Liwei Gu, and Keith R. Schneider, and published by the UF Department of Food Science and Human Nutrition, April 2015.

Preventing Foodborne Illness: Cyclospora cayetanensis

This photomicrograph of a fresh stool sample, which had been prepared using a 10% formalin solution, and stained with modified acid-fast stain, revealed the presence of four Cyclospora cayetanensis oocysts in the field of view. Cyclospora cayetanensis is a microscopic, spore-forming, intestinal protozoan parasite and a known cause of the gastrointestinal infection cyclosporiasis, often referred to as “traveler’s diarrhea” for its prevalence among visitors to regions where the species is endemic. These organisms have a protective covering that makes them resistant to disinfectants and that gives Cyclospora the ability to survive outside of hosts for extended periods. The incidence of cyclosporiasis has been increasing worldwide, with several documented cases in the United States and Canada. This 4-page fact sheet was written by Keith R. Schneider, Rachael Silverberg, Susie Richardson, and Renée Goodrich Schneider, and published by the UF Department of Food Science and Human Nutrition, March 2015. (Photo: CDC/DPDx – Melanie Moser)

Introduction to Social Network Research: Brokerage Typology?

Figure 2. Liaison brokerageBrokerage occurs constantly in our daily lives. You, an Extension educator, want to deliver a financial management program in two neighborhoods, A and B. Neighborhood A needs help immediately, but you have no connections there. You do have connections in the other neighborhood, and you know that a family in Neighborhood A has friends in Neighborhood B. In this example, the Neighborhood A family can be a broker to help you deliver a program in Neighborhood B. Extension educators can use brokerage typology to understand how information and resources flow among their target audiences, and by identifying the brokers in their local communities, to increase the connectedness of communities and expand the reach of Extension programs to a larger population. This 5-page fact sheet was written by Anil Kumar Chaudhary and Laura A. Warner, and published by the UF Department of Agricultural Education and Communication, March 2015.

Understanding Nitrogen Availability from Applications of Anaerobically Digested Beef-Cattle Manure in Florida Sandy Soil

Figure 1. Beef cattle in a confined feeding operation will produce manure that can be easily collected and digested anaerobically. Credit: George Hochmuth, UF/IFASAnaerobic digestion of livestock manure is a microbe-mediated process carried out in vessels or tanks, where the livestock wastes are digested slowly in environment absent of oxygen. The main products are biogas, anaerobically digested liquid (ADL), and solid (ADS), which can be land-applied as an organic soil amendment or a source of plant nutrients. This 4-page fact sheet provides research-based information about using anaerobically digested beef-cattle manure as an organic source of nitrogen for supplementing crop nutrition in Florida sandy soils, including initial N concentration, application timing, rate of application, and method of application.

Not All Landscape Palm Fertilizers Are Created Equal

Figure 1. A sample of an 8-2-12-4Mg landscape palm fertilizer showing the conspicuous granules of kieserite, a slow release form of magnesium sulfate. Credit: T.K. BroschatPalms are widely planted in Florida landscapes. Their bold leaf textures create a tropical or Mediterranean look that is highly desired by residents and tourists alike. But palms have very high nutritional requirements, and deficiencies of any element can result in conspicuous and unattractive symptoms on their large leaves. UF/IFAS research shows that the most effective fertilizer has 100% of the N, K, Mg, and B sources in slow-release or controlled-release form and that all of the Mn, Fe, Zn, and Cu sources should be water soluble. This 4-page fact sheet explains the reasons for this recommendation and how to ensure that you have a formulation that will be effective. Written by Timothy K. Broschat, and published by the UF Department of Environmental Horticulture, March 2015. (Photo Credit: T.K. Broschat)

Tree Assistance Program for Florida Citrus Greening

replacement trees in a nurseryIn September 2014, the USDA Farm Service Agency (FSA) announced additional support for commercial Florida citrus growers to manage greening, in the form of an expansion of the Tree Assistance Program (TAP). The original program assisted growers in the event the loss occurred within a single year due to a natural disaster such as a hurricane. The expanded TAP recognizes citrus greening (Huanglongbing, or HLB). The program provides growers cost-sharing financial assistance to replace trees that meet a mortality criterion within a time period of up to six years. This 4-page fact sheet describes eligibility requirements, how the program works, and how to calculate payments.

Managing Nitrogen Inputs and Outputs on a Dairy Farm

Figure 1. Nitrogen flows of a dairy forage system. Credit: R. HellmuthIn dairy production systems, nitrogen flows through both the forage crops and the dairy cows. Forage crops use nitrogen mineralized from manure for plant growth. Harvested crops are then fed to dairy cows that, in turn, use the nitrogen for their growth and milk production. When the cows excrete a portion of the consumed nitrogen as manure the cycle is renewed. This 5-page fact sheet focuses on the forage production aspect of the nitrogen cycle at a dairy farm.

Credit: iStock/Thinkstock.com (non-stick pan, waterproof textile, and fire fighting foam)/Digital Vision/Thinkstock.com (fast food)Perfluoroalkyl substances (PFASs) or perfluorochemicals (PFCs) are the most widespread and persistent manmade chemicals on earth. Common products that contain PFASs are Teflon pans, non-stick cookware, rain/waterproof jackets (like Gore-Tex), fire-fighting foams, food packaging, carpets, and furniture fabrics. PFASs stay in the environment for a long period of time, which means they can accumulate in organisms to levels that cause harmful effects. This 9-page fact sheet discusses the occurrence, use, exposure, and potential harmful effects of PFASs to humans and the environment, and suggests ways to reduce your exposure to PFSAs.

Floridian Consumer Perceptions of Local versus Organic Ornamental Plants

flowerHorticultural consumers in Florida are interested in local and organically produced plants. But these terms can mean different things in different regions. UF/IFAS researchers conducted a survey last summer which suggests that consumers in central Florida define local as plants that are grown near where they are sold and identify the most important local benefits as product safety, quality, and community support. Organic plants are perceived as requiring fewer chemical additives and being healthier for the environment. The importance of these traits varies by plant type. This 5-page fact sheet was written by Hayk Khachatryan and Alicia Rihn, and published by the UF Department of Food and Resource Economics, February 2015.

Chicken Mite (other common names: poultry red mite, roost mite) Dermanyssus gallinae (De Geer) (Arachnida: Acari: Dermanyssidae)

Figure 1. Adult chicken mite, Dermanyssus gallinae (De Geer). Credit: Lyle J. Buss, University of FloridaThe chicken mite affects egg-laying hens in many parts of the world, including Europe, Japan, China, and the United States. Although Dermanyssus gallinae affects birds in many regions, it is most prevalent in European countries, where egg industry losses are estimated at $177 million per year. It is a known vector for the St. Louis encephalitis virus, as well as other illnesses, such as fowl pox virus, Newcastle virus, and fowl cholera. In the United States, Dermanyssus gallinae is rarely found in caged-layer operations and is more commonly found in breeder farms. This 3-page fact sheet was written by Ethan Carter and Jennifer L.
