Nitrogen Contributions from Peanut Residues to Subsequent Crops

Peanut residues are concentrated in former windrows when residue spreaders are not used at harvest.

There is not enough evidence to support current peanut N credit recommendations in the Southeast. Nitrogen is released rapidly from peanut residues, and it moves quickly through light-textured soils found in this region. Only a relatively small amount of N from peanut residues is available when subsequent crops need it. This new 5-page document discusses peanut nitrogen credits, nitrogen release from peanut residues, crop performance following peanut, tillage and nitrogen release, and peanut residue distribution and nitrogen release. Written by Arun Jani and Michael J. Mulvaney, and published by the UF/IFAS Agronomy Department, April 2019.

Early Detection and Rapid Response (EDRR) to Nonnative Wildlife in South Florida

Michiko Squires and a Burmese python

Invasive nonnative wildlife threaten successful restoration of Everglades ecosystems in south Florida. If nothing is done while an invasion is in the beginning stages, populations can grow and become much more difficult to manage, as happened with the Burmese pythons. This 4-page fact sheet written by Justin R. Dalaba and Frank J. Mazzotti and published by the UF/IFAS Wildlife Ecology and Conservation Department explains how the Early Detection and Rapid Response method works and how to apply it to increase the likelihood that an invasion will be successfully contained or eradicated while an invasive population is still small and localized.

Butterfly Pea (Clitoria ternatea) Flower Extract (BPFE) and Its Use as a pH-Dependent Natural Colorant

BPFE extract at normal pH (blue), lowered pH (green), and raised pH (purple)

Butterfly pea (Clitoria ternatea), a twining vine native to Southeast Asia, produces deep blue to purple flowers that bloom nearly year-round in ideal conditions. When extracted in a liquid, the addition of a mild acid such as lemon or lime juice turns the naturally deep blue to purple color into a much lighter pink or purple color, giving the extract its color-changing ability. This new 5-page publication of the UF/IFAS Environmental Horticulture Department outlines the use of butterfly pea flower extract (BPFE) as a pH-dependent natural colorant, including an explanation of the science behind the color change, detailed parameters for flower extraction, instructions for storage and processing of the extract as well as a discussion of some of the other benefits of using BPFE. Written by Sean Michael Campbell and Brian Pearson.

Cavity-nesting eastern bluebirds use naturally occurring holes in trees, cavities hollowed out by woodpeckers, or man-made houses. You can maximize your chances of attracting bluebirds long-term by providing appropriate housing options and locating the houses in suitable sites. This 3-page fact sheet written by Holly K. Ober and published by the UF/IFAS Department of Wildlife Ecology and Conservation provides recommendations on housing for bluebirds in north Florida.

While hot and humid conditions cause grief for dairy producers, additional impacts of heat and humidity on the dairy cow are sometimes overlooked. These conditions and their associated losses in productivity pose a growing concern to dairy producers, as more frequent and severe fluctuations in temperature, precipitation, and droughts are predicted to occur in the United States. This new 4-page document discusses heat stress in the dairy industry, the Florida dairy heat stress abatement survey, and heat stress abatement for lactating cows, dry cows, and dairy calves.

La Granada en Florida: Una fruta de arbol para Florida?

Árbol de granada ('Wonderful' cv.)

El potencial económico en la producción comercial para el cultivo de granadas en Florida es actualmente desconocido en este momento. La investigación científica continúa sobre la posibilidad de encontrar variedades de granadas que puedan crecer en Florida. Las condiciones ambientales, con una alta temporada húmeda en la Florida, y un clima caluroso, son factores que son favorables para las enfermedades en las granadas y eso reduce la calidad de esta fruta, especialmente para las variedades de temporada tardía como la variedad ‘Wonderful’. ‘Wonderful’ es el principal cultivar comercial que se originó en la Florida. Para reducir las enfermedades y evitar la competencia de comercialización con las granadas de California, la investigación para la producción de granadas en la Florida debe centrarse en buscar variedades de temporada temprana que puedan cosecharse en julio y agosto. This six-page document is the Spanish translation of HS44, The Pomegranate.

Good Agricultural Practices (GAPs) and Good Handling Practices (GHPs) encompass the general procedures that growers, packers and processors of fresh fruits and vegetables should follow to ensure the food safety of their product. GAPs usually deal with preharvest practices (i.e., in the field), while GHPs cover postharvest practices, including packing and shipping. We will use the term GAPs in this fact sheet to generally cover pre- and postharvest practices associated with the safe handling of produce, both fresh and minimally processed. This five-page introduction to the Food Safety on the Farm series provides an overview of GAPs and GHPs, summarizing major principles and recommendations of later documents in the series. Written by Jaysankar De, Christopher R. Pabst, Jessica Lepper, Renée Goodrich Schneider, and Keith R. Schneider and published by the UF/IFAS Food Science and Human Nutrition Department.

Protecting Perishable Foods During Transport by Truck and Rail

Airfoil accessories to increase fuel efficiency: underbody fairings

The importance of protecting perishable foods from loss of quality during transport has long been recognized. Increased recognition of the importance of the transport link in the food distribution cold chain in securing the safety of perishable foods has more recently become as well recognized.
This updated edition reflects the dynamic changes and innovations in the handling and transportation of perishable foods. Some of these include improved insulation and air movement, microprocessors for more efficient refrigeration, expert systems to control the transport environment and conserve fuel energy, and the use of telematics to monitor and control the performance of refrigerated vehicles during transit. This edition includes descriptions and recommendations for food transported over the road and by rail in marine containers, as well as in railcars. This 214-page revision was written by J. K. Brecht, Steven A. Sargent, Patrick E. Brecht, Jorge Saenz, and Leonard Rodowick and published by the UF/IFAS Horticultural Sciences Department in cooperation with the USDA AMS Transportation Services Division.
