Florida's Use-Value Assessment Law: Questions and Answers for Miami-Dade County Agricultural Classification (FE890)

Use-value assessment is the most widely used technique in the United States today for maintaining land in agricultural production. Although general guidelines are provided to Florida counties on the application of the state’s use-value assessment law, counties may vary slightly in the application and determination of the agricultural land’s value. Therefore, it is important for agricultural landowners to understand the guidelines used to determine value in the county where the land is assessed and taxed. This 5-page factsheet applies specifically to Miami-Dade County, Florida. Written by Edward A. Evans, Mauricio Mosquera, Rodney L. Clouser, and Jonathan Crane, and published by the UF Department of Food and Resource Economics, April 2011.

Forest Resources

Eucalyptus and Corymbia Species for Pulpwood, Mulchwood, Energywood, Windbreaks, and/or Phytoremediation (CIR1194/FR013)

In Florida, Eucalyptus species grow faster than our native tree species. Certain species, when planted on suitable sites and managed properly, can produce commercial products such as pulpwood, mulchwood, and energywood, can remediate environmental problems, or may be used as windbreaks for citrus and vegetables. This circular describes potential applications and presents planting guidelines for these three species. This revised 7-page fact sheet was written by D. L. Rockwood and G. F. Peter, and published by the UF Department of School of Forest Resources and Conservation, March 2011.

Redheaded Pine Sawfly Neodiprion lecontei (Fitch) (EENY488/IN882)

Neodiprion lecontei is an important defoliator of commercially grown pine, as the preferred feeding conditions for sawfly larvae are enhanced in monocultures of shortleaf, loblolly, and slash pine, all of which are commonly cultivated in the southern United States.

Agronomic Crops

Weed Management in Rice (SSAGR10/WG001)

Successful weed control is essential for economical rice production in the Everglades Agricultural Area (EAA). Refer to this revised 5-page fact sheet for current management recommendations. Written by D.C. Odero and C. Rainbolt, and published by the UF Department of Agronomy, March 2011.

Managing Against the Development of Herbicide-Resistant Weeds: Sugarcane (SSAGR244/SC077)

Although it is likely that small populations of herbicide-resistant weeds are already present in the Everglades Agricultural Area (EAA), herbicide resistance is currently not a significant problem. The continued use of integrated and properly managed weed control programs should ensure that resistance does not become a major issue in the future. In order to successfully manage herbicides against the development of herbicide-resistant weeds, you must have a basic understanding of which herbicides have the same site of action. This revised 4-page fact sheet lists herbicides by group number, site of action, chemical family, common name, and trade name.

Written by D.C. Odero, B.A. Sellers, J.A. Ferrell, and G.E. MacDonald, and published by the UF Department of Agronomy, March 2011.

Creep Grazing for Suckling Calves: A Pasture Management Practice (SSAGR211/AG193)

The concept of creep grazing is based on the fact that the nutritional requirements of suckling calves are much higher than those of cows. Calves creep grazing on high quality forage that provides high intake of digestible energy and protein make extra growth while the cows are grazing lower quality pasture.
