This 3-page document discusses methods and pieces of equipment available to estimate forage moisture. Written by M. Wallau and J. Vendramini, and published by the UF/IFAS Agronomy Department, revised June 2019.
Florida's unique climatic characteristics allow for forage production most of the year with a large variety of possible forage choices. Independent of the size of the operation and number of horses, good forage planning can help reduce feeding costs, environmental impacts, and nutritional disorders caused by high-concentrate feeding. With the exception of high-performance animals, horses can meet most of their nutritional needs from pasture. However, achieving this requires careful planning and implementation of a forage production and utilization program. This 9-page document discusses intake and nutrient requirements, pasture planning, forage species, and pasture management. Written by M. Wallau, E. L. Johnson, J. Vendramini, C. Wickens, and C. Bainum, and published by the UF/IFAS Agronomy Department, revised January 2019.
Establishing forages from seeds often requires precision equipment to achieve specific seeding rates for a proper pasture stand. Most pieces of equipment have calibration charts, which are useful guides for making an initial setting. However, due to variations in seed size, purity, moisture content, equipment performance, ground speed, and other factors, calibrating equipment prior to each use is recommended. This 5-page document discusses a few calibration techniques for drills and broadcast spreaders. Written by Marcelo Wallau, Joao Vendramini, and Ed Jennings, and published by the UF/IFAS Agronomy Department, revised November 2018.
Nitrogen (N) is one of the major off-farm inputs in livestock systems, either in the form of N fertilizer or purchased feed. Fortunately, you can reduce those expenses by growing your own nitrogen using forage legumes. Rhizoma perennial peanut (RPP) is a legume adapted to the Florida environment that grows well in mixtures with bahiagrass. This 4-page fact sheet discusses varieties, establishment, weed management, grazing management, and the cost-share program. Written by Jose Dubeux, Lynn Sollenberger, Joao Vendramini, Marcelo Wallau, Ann Blount, Liza Garcia-Jimenez, Erick Santos, and David Jaramillo, and published by the UF/IFAS Agronomy Department, July 2018.
Brunswickgrass (Paspalum nicorae Parodi) is becoming a problematic weed in summer perennial grass pastures in the Southeast. The plant is competitive with bahiagrass
and bermudagrass. Since it is less palatable, it can eventually dominate a perennial grass pasture. Brunswickgrass has become naturalized and has reportedly contaminated bahiagrass seed fields and pastures in the southeastern states, including some of the important counties for seed production in Florida, such as Gilchrist, Levy, Alachua, Citrus, and Sumter. This 4-page fact sheet provides an overview of brunswickgrass and discusses its appearance, variety/germplasm, and management. Written by Ann Blount, Marcelo Wallau, Brent Sellers, Dennis Hancock, Leanne Dillard, Jose Dubeux, Cheryl Mackowiak, Joao Vendramini, and Clay Cooper, and published by the UF/IFAS Agronomy Department, April 2018.
Warm-season grasses are vital to livestock production systems and dominate ground cover in tropical and subtropical areas.

Griffin, Joao Vendramini, Diane Rowland, and Maria L. Silveira and published by the UF/IFAS Agronomy Department, November 2017.
This four-page publication provides basic information about land application of biosolids to pastures and hayfields in Florida. The information contained in this document should be of interest to stakeholders, biosolids managers, students, and scientists interested in topics related to biosolids management practices and the potential benefits and risks associated with biosolid land application. Written by Maria L. Silveira, George A. O’Connor, and Joao M.B. Vendramini and published by the Department of Soil and Water Sciences.
UF/IFAS Extension faculty and state specialists involved in the UF/IFAS South Florida Beef-Forage Program (SFBFP), in conjunction with the UF/IFAS Program Evaluation and Organizational Development unit, created a survey in 1982 that is used to evaluate ranch management practices. The survey is updated and distributed every five years to ranchers in 14 south Florida counties: Charlotte, Collier, DeSoto, Glades, Hardee, Hendry, Highlands, Hillsborough, Lee, Manatee, Martin, Okeechobee, Polk, and Sarasota. There were 102 anonymous responses in 2011. This 6-page fact sheet discusses characteristics of beef operations in south Florida, reproduction, production, marketing, herd health, nutrition, forage production, and environment. Written by Sonja Crawford, Christa Kirby, Tycee Prevatt, Brent Sellers, Maria Silveira, Bridget Stice, Joao Vendramini, and Lindsey Wiggins, and published by the UF Agronomy Department, October 2016.
This 6-page fact sheet discusses beef demand in the context of a growing population, beef production’s greenhouse gases and their effect on the environment, the great advantage of ruminants, generating accurate greenhouse gas emissions estimates, greenhouse gas emissions by economic sector, and mitigation strategies.

Many forage-based livestock production systems in Florida are characterized by extensive grazing with minimal inputs of commercial fertilizer and supplemental feed. In these systems, adequate soil fertility conditions are essential to sustain forage production. If nutrients become deficient, pasture and animal performance is reduced, and the economic returns of livestock operations may decline. This 3-page fact sheet discusses the different nutrient pathways in grazing pastures to help producers better understand how to promote nutrient cycling and pasture sustainability. Written by Maria L. Silveira, Joao M. B. Vendramini, Hiran M. da Silva, and Mariana Azenha, and published by the UF Department of Soil and Water Science, January 2013.
Establishment of an excellent, uniform stand of forage in a short period of time is important. The producer needs to do everything possible to ensure successful establishment. Several requirements that must be met are briefly discussed, along with various planting methods. This revised 8-page fact sheet was written by Y.C. Newman, J. Vendramini, C.G. Chambliss, M.B. Adjei, and published by the UF Department of Agronomy, April 2011.
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.
