This 9-page fact sheet describes its distribution, history and impacts, ecological overview, integrated management and identification. Written by Colette C. Jacono and Kenneth A. Langeland, and published by the UF Department of Agronomy, April 2011.



Biology and Control of Ragweed Parthenium in Non-Cropland (SSAGR343/AG353)

Ragweed parthenium is considered a noxious weed in many parts of the world because of its allelopathic effect on other plants and the health risks it poses to humans. It causes allergic contact dermatitis, rhinitis, and respiratory problems in sensitive humans. Learn more in this 3-page fact sheet was written by D.C. Odero, B.A. Sellers, and J.A. Ferrell, and published by the UF Department of Agronomy, April 2011.



Aquatic Weeds: Crested Floating Heart (Nymphoides cristata) (SSAGR344/AG354)

Crested floating heart is a native of Asia, but was introduced to North America through the aquatic plant nursery trade and marketed as ‘snowflake.’ In the United States, crested floating heart escaped from cultivation and became established in Florida water bodies. Learn how to identify and manage this aquatic weed in this 5-page fact sheet written by Leif N. Willey and Kenneth A. Langeland and published by the UF Department of Agronomy, April 2011.



Getting Involved


Evaluating Certified Coffee Programs (WEC306/UW351)

In recent years, there has been a growing interest among consumers to buy products that follow strict standards in their production process and that also are healthy and safe. In the case of coffee, people in the United States are not only interested in the quality and origin of coffee, but many are also concerned about the social, economic, and environmental aspects of coffee production. Coffee is taking the lead in developing standards to address these concerns. This 6-page fact sheet explains the certification process and describe the various certification programs and what they mean. Written by Gloria M. Lentijo and Mark Hostetler, and published by the UF Department of Wildlife Ecology and Conservation, February 2011.





Nutrient Mass Budget -The Case of Florida Watermelon Phosphorus Export (SL342/SS547)

Watermelon provides an interesting example of how the phosphorus nutrient balance on the farm has changed over time with changes to production practices and acreage. In this 4-page paper the calculations are described for the export of phosphorus from Florida in the state’s watermelon fruits. Written by George Hochmuth and Jerry Bennett and published by the UF Department of Soil and Water Science, January 2011.
