Identification and Control of Southern Sandbur (Cenchrus echinatus L.) in Hayfields (SSAGR364/AG373)

Figure 1. Southern sandbur.Southern sandbur is an annual grass that grows in pastures and cropland throughout the warm areas of the southern United States from Virginia to California. This native grass is adapted to dry, sandy soils and has a shallow, fibrous root system. It can easily invade a poorly managed field, diminishing the quality of a hay crop or grazing pasture. Southern sandbur seeds start to germinate in late spring, and germination continues through the summer and fall. Flowering occurs in late fall, and growth is consistent until the first frost.

Production of Miscanthus x giganteus for Biofuel (SSAGR292/AG297)

Figure 2. Stands of Miscanthus x giganteus reach maturity in July in FloridaThe bioenergy industry has primarily used Miscanthus for combustion in power plants. It has desirable properties of low water and ash contents following a dry-down period before harvest. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol and other biofuels.

Cogongrass (Imperata cylindrica) Biology, Ecology, and Management in Florida Grazing Lands (SSAGR52/WG202)

Figure 1. Cogongrass plants are yellow to green in color. Note that the edges of the leaf tend to have more yellow than green.Cogongrass is found on every continent and is considered a weedy pest in 73 countries. In the U.S., cogongrass is found primarily in the Southeast. It was accidentally introduced into Alabama in the early 1900s, and purposely introduced as a potential forage and soil stabilizer in Florida (and other states) in the 1930s and early 1940s. However, soon after investigations began it was realized that cogongrass could be a weedy pest. Since its introduction, cogongrass has spread to nearly every county in Florida. In some cases, it has completely taken over pastures so that it is the only species present. This is a common thread where cogongrass invades; it quickly displaces desirable species and requires intensive management. This 5-page fact sheet was written by B. A. Sellers, J. A. Ferrell, G. E. MacDonald, K. A. Langeland, and S. L. Flory, and published by the UF Department of Agronomy, August 2012.

Phosphorus Fertilizer Recommendations for Sugarcane Production on Florida Organic Soils (SSAGR348/SC091)

Much of the sugarcane grown in South Florida is on organic soils in the Everglades Agricultural Area, which is a phosphorus-limited system. Phosphorus loads in drainage water in the Everglades Agricultural Area are an environmental concern so it is important for sugarcane growers to use best management practices such as soil testing and to follow fertilizer recommendations. This document contains updated UF/IFAS phosphorus fertilizer recommendations for Florida organic soils. This 7-page fact sheet was written by J. Mabry McCray, Ronald W. Rice, and Alan L. Wright, and published by the UF Department of Agronomy, July 2012. http://edis.ifas.ufl.edu/sc091

Estimating Amount of Forage in Hay Fields and Pastures (SSAGR360/AG369)

Figure 1AForage serves as the primary source of nutrients for livestock in Florida, and efficient use of forage is critical to the livelihood of Florida farmers and ranchers. Estimating the amount of forage in a pasture can provide useful information when making management decisions. There must be enough material in the field to justify the cost of using harvesting equipment; otherwise, the area should be grazed. This 2-page fact sheet contains instructions for a simple method to determine the approximate amount of forage in hay fields and pastures. Written by T. Wilson, C. Sanders, J. Breman, and L.

Control of Lantana in Pastures (SSAGR359/AG368)

Figure 2. Lantana flowers of (A) purple/white and (B) red/yellow are common.Lantana is currently one of the top 10 most troublesome weeds in Florida. Although it is still sold as an ornamental, commercial varieties are sterile and considered to be non-invasive. It can quickly invade disturbed sites by producing plant toxins in its roots and stems, that either slow the growth of other plants or totally remove them. These leaf toxins are damaging to grazing animals. If animals consume the leaves, they often begin to show symptoms of skin peeling or cracking. Once animals show these symptoms, there is little or no treatment that can reverse the process. Although lantana’s leaves are poisonous, its berries are not. Birds readily consume the fruit and disperse the seed. This 2-page fact sheet was written by J. Ferrell, B. Sellers, and E. Jennings, and published by the UF Department of Agronomy, February 2012.

Production of Biofuel Crops in Florida: Sweet Sorghum (SSAGR293/AG298)

Figure 2. Sweet sorghum planted in FloridaVarieties of sorghum with a high concentration of soluble sugars are attractive as a potential energy crop because of the easy accessibility of readily fermentable sugars combined with very high yields of green biomass. Similar to sugarcane, the sap of sweet sorghum is extracted by milling, and can be easily fermented to produce ethanol. Other products from sweet sorghum include syrup, molasses, and crystal sugar.
