A Farm to School Procurement Calculator for Specialty Crop Producers and School Food Service Staff

Farm to School logoFlorida Farm to School programs are designed to connect producers with schools. But school food service staff make their purchasing decisions in terms of servings and producers pack their products by weight. General calculators and guides designed for national Farm to School programs don’t address Florida’s diverse production of fresh fruits and vegetables. This procurement calculator and guide for Florida Farm to School programs was written by Jonathan A. Watson, Danielle Treadwell, Anna Prizzia, and Kelli Brew, and published by the UF Department of Horticultural Sciences, September 2014.

African malaria mosquito Anopheles gambiae Giles (Insecta: Diptera: Culicidae)

Figure 1.  Female Anopheles gambiae Giles taking a blood meal.Anopheles gambiae Giles is commonly called the African malaria mosquito because it is the most efficient vector of human malaria in the Afrotropical Region. They are considered to be one of the world’s most important human malaria vectors because of their susceptibility to the Plasmodium parasite, their preference for humans as a host, and their indoor-feeding behavior. Due to their short development time and their preference for developmental habitats near human dwellings, Anopheles gambiae are considered effective vectors of human malaria, as well as lymphatic filariasis (elephantiasis).

Pool Chemicals and Personal Safety

Figure 1. Pool chemicals, distributed through box stores, are classified as pesticides.Pool chemicals are among the most common household substances and are used to protect health in recreational waters. Pool chemicals containing chlorine safeguard against recreational-water illnesses caused by disease-causing pathogens, such as the diarrhea-causing Cryptosporidium. They also enhance disinfection by regulating water pH. But even though these materials are regularly handled by homeowners, most don’t ever realize that they are handling pesticides.

Acoelorrhaphe wrightii: Paurotis Palm

st058The paurotis or Everglades palm is a clustering, fan-leaved palm with very slender stems. It can reach heights up to 30 feet, with a spread of 20 feet. The light green leaves have blades about 2 feet across on spiny petioles up to 3 feet long. The stems are covered with fibers and persistent leaf bases. In the spring paurotis palms produce large inflorescences of creamy white flowers that extend well beyond the foliage. These are followed in the summer by ¼-inch round fruits that pass through green and orange stages but turn black when completely ripe. Paurotis palms are rather slow-growing and are not tolerant of salt spray. This 3-page fact sheet was written by Timothy K. Broschat, and published by the UF Department of Environmental Horticulture, September 2014.

Citrus Mechanical Harvesting Systems?Continuous Canopy Shakers

Figure 2. CSC system (Photo courtesy of Paul Meador, Everglades Harvesting, LaBelle, FL)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

Figure 2. Coe-Collier shaker unit (Photo courtesy of Barbara Hyman, UF/IFAS)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. This 4-page fact sheet was 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.
