An Overview of Carbon Markets for Florida Forest Landowners
Payments for sequestering carbon in forests can be an important supplemental income source in the southern US which includes one-third of the contiguous US forest carbon stocks and supplies 16% of the world’s wood. It is difficult to understand the carbon market and certification options available to Florida forest landowners and the possible risks of participating in them. To address this need, UF/IFAS forest management specialists provide this overview of forest carbon markets in the United States as of 2014 and compare key features of the four major carbon offset certification options. This 9-page fact sheet was written by José R. Soto, Francisco J. Escobedo, and Damian C. Adams, and published by the UF Department of School of Forest Resources and Conservation, July 2014.

Citrus Mechanical Harvesting Systems–Continuous Canopy Shakers
Mechanization has been the hallmark of American agriculture. Nearly 100 percent of the agronomic crops grown in the United States are plowed, planted, and harvested with mechanical equipment. Mechanical harvesting equipment for sweet oranges has been studied extensively since the 1970s and during the 2005/06 harvest season, trunk and canopy shakers harvested more than 36,000 acres of Florida citrus. Mechanically harvested citrus acreage, however, has decreased significantly since 2005. During the 2012/13 season, less than 9,000 acres were mechanically harvested (FDOC 2013). Nevertheless, development and adoption of mechanical harvesting technology is important to the long-term economic sustainability of the Florida orange juice processing industry. This 5-page fact sheet describing canopy shakerswas written by F.M. Roka, R.J. Ehsani, S.H. Futch, and B.R. Hyman, and published by the UF Department of Food and Resource Economics, August 2014.

Citrus Mechanical Harvesting Systems–Trunk Shakers
While citrus growers are rightfully concerned about restoring the health of their HLB-infected trees, more study and consideration should be given to mechanical harvesting. The costs to grow and harvest citrus have been escalating significantly since 2006, and the cost savings potential from mechanical harvesting technologies can help Florida growers remain economically viable.

Waterhyacinth: Florida's Worst Floating Weed
Waterhyacinth is one of the world’s worst aquatic weeds and is Florida’s most intensively managed floating plant. Dense mats formed by this species interfere with human uses of water bodies and disrupt ecosystems by preventing penetration of light and oxygen into the water column. This attractive, free-floating aquatic plant grows throughout the year in southern Florida but often dies back during the winter in the northern parts of the state. Waterhyacinth is cultivated as a water garden and pond plant, but cultivation, sale, and possession of this noxious weed is prohibited in Florida. This 5-page fact sheet was written by Lyn A. Gettys, and published by the UF Department of Agronomy, September 2014.

Survival of Foodborne Pathogens on Berries
Fresh and frozen berries are popular foods. When berries are picked for fresh consumption, they are usually packed directly without washing because they are highly perishable. There is typically no “kill step” that would eliminate pathogens on fresh or frozen berries. Foodborne illness outbreaks have been associated with the consumption of fresh or frozen berries that were contaminated with pathogenic viruses, parasites, or bacteria. Contamination can occur before or during harvest or during final preparation. This 11-page fact sheet was written by Mary Palumbo, Linda J. Harris, and Michelle D. Danyluk, and published by the UF Department of Food Science and Human Nutrition, November 2014.

Peach Scab
Peach scab is a disease caused by the fungus Cladosporium carpophilum. The pathogen can infect other fruits and nuts within the Prunus species, like almonds, apricots, nectarines, and plums. Peach scab is common during periods of humid weather because rain splashes the conidia (asexual spores) from the fungus between leaves, twigs, and fruit in the tree canopy, which spreads the disease. This 6-page fact sheet was written by Daniel Mancero-Castillo, Mercy Olmstead, and Phillip Harmon, and published by the UF Department of Horticultural Sciences, July 2014.

Facts about Wildlife Diseases: Pseudorabies
Pseudorabies primarily affects swine, but cattle, sheep and other mammals are susceptible to infection. Humans are not at risk. The superficial symptoms of this viral disease resemble rabies symptoms, thus the name pseudorabies. Although eliminated in commercial animals, feral swine populations in the United States continue to circulate the disease and provide a reservoir for outbreaks. Texas, Oklahoma, Florida, and Hawaii all have dense populations of feral swine with a high prevalence of pseudorabies. Feral swine, therefore, pose a serious risk to commercial swine operations, livestock, companion animals, and wildlife. This 4-page fact sheet was written by Samantha Wisely, and published by the UF Department of Wildlife Ecology and Conservation, August 2014.

Can Maternal Colostrum Be Replaced by Commercial Products for Feeding Newborn Calves?
Colostrum management and feeding are critical for calf health, calves’ future productive life, and farm profitability. Current recommendations state that a calf needs to ingest at least 150–200 g of immunoglobulin G within two hours of birth, but when colostrum quality is poor or unavailable, colostrum replacer may be a suitable alternative. This 3-page fact sheet presents the results of a recent publication that evaluated the effects of feeding maternal colostrum, one dose of plasma-derived colostrum replacer, or one dose of colostrum-derived colostrum replacer on serum total protein, immunoglobulin G concentration, calf morbidity, calf mortality, and weight gain from birth to weaning.

What Is the Most Cost-Effective Breeding Program for Breeding Heifers: Timed AI, Estrous Detection, or a Combination of Both?
As any other business enterprise, the sustainability of a dairy farm is highly dependent on economics. In order to obtain a profitable return on assets, there is a constant need to maximize outputs and, oftentimes, to minimize inputs. Reproduction influences both milk production and number of replacement heifers available on a farm; therefore, reproductive efficiency becomes a key determinant of dairy cow profitability. This 3-page fact sheet presents information from recently published work that looked at the economics of different reproductive programs for breeding heifers that use timed AI only, estrus detection only, or a combination of both.

Can GnRH Be Used to Induce Ovulation Early in Lactation and Improve Fertility in Dairy Cows?
It is well established that early cyclicity results in increased pregnancy per artificial insemination and decreased time to pregnancy. But none of the previous studies has used synchronization programs such as the Presynch-Ovsynch as part of their reproductive management. This 2-page fact sheet presents the results of a recent paper that evaluated the effects of administration of GnRH at 17 ± 3 and 20 ± 3 DIM in Holstein dairy cows without a corpus luteum (CL) on induction of ovulation, uterine health, and reproductive outcomes.

Targeting ADG of Developing Replacement Heifers Using Age and Body Weight
Heifer development continues to be one of the largest expenses to cow-calf operations, primarily due to cost of feed. Replacement heifers should be bred to calve at 24 months of age in order to maximize lifetime productivity of breeding females. Therefore, heifers should conceive at 15 months of age and achieve puberty at 13–14 months of age because heifers are infertile on the pubertal estrous cycle. This 4-page fact sheet was written by Phillip Lancaster and Cliff Lamb, and published by the UF Department of Animal Sciences, September 2014.

Pests and Fungal Organisms Identified on Olives (Olea europaea) in Florida
Olive production in Florida has increased over the last few years. As trees become available in nurseries many homeowners are planting them in their landscapes. Fortunately, olives are a relatively pest-free species, but some occasional invaders can be a nuisance or cause lasting harm. A few plant pathogens that may infect olives also can lead to a decline in overall plant health, fruit yield, or the visual appearance of plants. Following correct cultural practices when growing olives can reduce your chances of tree loss from pests and diseases. A survey of olive production and interviews with Florida growers in 2014 identified the pests and diseases described in this 5-page fact sheet, written by Jennifer L. Gillett-Kaufman, Sandra A. Allan, Jonael H. Bosques-Mendez, and Lyle J. Buss, and published by the UF Department of Entomology and Nematology, September 2014.
