Production of Giant Reed for Biofuel (SSAGR318/AG327)

Figure 2. Giant reed with flower headsGiant reed is currently being evaluated as a potential biomass energy crop in Florida, even though some scientists and those in other states consider it to be a noxious or invasive weed. This 4-page fact sheet discusses the adaptation and production of giant reed as a potential energy crop and presents measures for controlling giant reed as an escaped weed. It does not give specific recommendations on whether it is better to control giant reed or produce it for biofuel.

Fertilizer Experimentation, Data Analyses, and Interpretation for Developing Fertilization Recommendations: Examples with Vegetable Crop Research (SL345/SS548)

theoretical data showing crop response to nitrogen fertilizationFertilizer recommendations contain several important factors, including fertilizer form, source, application timing, placement, and irrigation management. Another important part of a fertilizer recommendation is the amount of a particular nutrient to apply. The optimum fertilizer amount is determined from extensive field experimentation conducted for several years, at multiple locations, with several varieties, etc. This 10-page fact sheet focuses on the research principles behind determining the optimum rate of fertilizer, including experimentation and interpreting research results for optimum crop production and quality in conjunction with minimal environmental consequences. Authors George Hochmuth, Ed Hanlon, and Allen Overman use examples from research with vegetable crops in Florida and emphasize that how one interprets the results is as important as how one conducts the research.
