Pastures and Forage Crops for Horses

Horse grazing bermudagrass.

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.

Calibrating Forage Seeding Equipment

Oat and ryegrass seeds mixed in the main seedbox. Smaller ryegrass seed increases the speed of the flow compared to oat only.

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.

Strip-Planting Rhizoma Peanut into Grazing Systems

Yoana Newman discusses forage grass at a small farms workshop.

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.

Brunswickgrass or Paspalum nicorae: A Weed Contaminant in Southern Pastures and Bahiagrass Seed Production Fields

Closely grazed bahiagrass pasture with patches of brunswickgrass in late September (toward the end of the growing season) in Levy County, FL.

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.

2011 South Florida Beef Forage Survey Results

Young heifers at the Range Cattle Research Station. These beef cows are all at least 3/4 Angus. They are part of an attempt to create a white Angus breed. During the summer the white cows, coined "white Angus" by the researchers in Ona, have a body temperature that is one degree cooler than the traditional black Angus. UF/IFAS Photo: Sally Lanigan.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.

Nutrient Cycling in Grazed Pastures (SL376/SS578)

Figure 1. Schematic diagram showing how nutrients cycle through several pools, including the atmosphere, soil, plants, and animals.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.

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.

Production of Biofuel Crops in Florida: Switchgrass (SSAGR291/AG296)

Nationwide, switchgrass is recommended for biofuel production because of its wide range of adaptation and high potential dry matter yield with relatively low fertility input. It can be used for both lignocellulosic ethanol production and in electricity generation, complementing coal as a co-firing agent supplement. Less is known about switchgrass production in Florida than other biofuel crops. This 4-page fact sheet describes the biofuel potential, biology, production, potential yields, production challenges, estimated costs, and environmental concerns. Includes references.
