The Keetch-Byram Drought Index (KBDI) is generally used to determine potential wildfire hazards across the southeastern United States and is calculated daily by the Florida Department of Agriculture and Consumer Services, Division of Forestry. KBDI is a continuous reference scale for estimating the dryness of the soil and duff layers. Forest managers have identified several uses for the KBDI in wildfire management. This 5-page fact sheet explains the nuts and bolds of the KBDI and how forecast the index on agroclimate.org. Written by Clyde W. Fraisse, Norman E. Breuer, and David Zierden and published by the UF Department of Agricultural and Biological Engineering, February 2011.
AE463, an 8-page illustrated fact sheet by Norman E. Breuer, Clyde Fraisse and David Zierden, is the Spanish-language version of ABE352/AE267 Climate Forecast and Decision Making in Agriculture. It describes the type of strategic pre-season decisionmaking that should take into consideration climate forecasts, how climate is predicted, how to interpret the forecasts, the climate of Florida, and climate forecast applications to agriculture in Florida. Includes references. Published by the UF Department of Agricultural and Biological Engineering, June 2010.
AE464, a 3-page fact sheet by Norman Breuer, Matthew Langholtz, David Zierden and Clyde Fraisse, is the Spanish language version of ABE354/AE282: Using Seasonal Climate Variability Forecasts to Plan Forest Plantation Establishment. It provides strategies to consider for pine plantation establishment in Florida and southern Alabama and Georgia, where seasonal climate conditions can be better predicted because it is affected by the El Niño Southern Oscillation (ENSO) phenomenon. Includes references. Published by the UF Department of Agricultural and Biological Engineering, July 2010.
AE462, a 9-page illustrated fact sheet by Norman Breuer, Clyde Fraisse, Gene McAvoy and David Letson, is the Spanish language version of “CIR1450/AE269 Using Seasonal Climate Variability Forecasts: Risk Management for Tomato Production in South Florida.” It describes the difference between weather and climate, suggests climate-based management options available to tomato growers, and discusses economic and risk management implications of seasonal climate variability for tomato producers and extensionists in South Florida. Includes references. Published by the UF Department of Agricultural and Biological Engineering, May 2010.
AE452, a 6-page illustrated fact sheet by Clyde W. Fraisse and Alicia Whidden, introduces a new web-based tool for agricultural producers to track and forecast chill accumulation during the winter season to reduce risks associated with climate variability in the southeastern U.S.A. Includes references. Published by the UF Department of Agricultural and Biological Engineering, January 2010.
AE450, a 5-page illustrated fact sheet by Willingthon Pavan, Clyde W. Fraisse, and Natália A. Peres, describes a web-based tool for timing fungicide applications in strawberries that can reduce the number of sprays and cost of production, especially in years when the conditions for disease are not favorable. Includes references. Published by the UF Department of Agricultural and Biological Engineering, August 2009.
AE-447, an 11-page illustrated instructor’s guide by Clyde W. Fraisse, William R. Lusher, Melissa Griffin, and Arthur A. Texeira, provides instructors with directions, equipment lists, background resources, instructions for setup, script for the power point presentation, conducting the workshop, and followup questions. Includes relevant Sunshine State Standards in Science, Mathematics, and Visual Arts. Published by the UF Department of Agricultural and Biological Engineering, March 2009.
AE443, a 7-page fact sheet by Solomon G. Haile, Clyde W. Fraisse, P.K. Ramachandran Nair and Vimala D. Nair, is part of the Greenhouse Gas Mitigation in Forest and Agricultural Lands series. It provides basic information about greenhouse gases (GHGs), the greenhouse effect, and global warming, and sources of GHG emissions from forest and agricultural lands and discusses land management practices that have potential to reduce GHG emissions in the agricultural and forestry sectors of Florida. Includes refererences. Published by the UF Department of Agricultural and Biological Engineering, December 2008.
AE435, an 8-page fact sheet by Solomon G. Haile, Clyde W. Fraisse, Vimala D. Nair, and P.K. Ramachandran Nair, addresses some basic questions regarding the prospects of carbon (C) sequestration in forest and agricultural lands and examines the C sequestration potential of different land management practices that could play a role in GHG mitigation strategies. Includes references. Published by the UF Department of Agricultural and Biological Engineering, September 2008.
