Salmonella y Escherichia coli enteropatogena en el ambiente de produccion de cultivos: fuentes potenciales, supervivencia y gestion (SL375Span/SS577)

El objetivo de esta publicación EDIS es poner en evidencia los descubrimientos recientes que se enfocan en la ecología de los patógenos humanos en el área de producción de cultivo. Una mejor comprensión de cómo los patógenos persisten fuera de los huéspedes animales en el agua para la agricultura, en el suelo y en las plantas, tendrá grandes impactos en el manejo y procesamiento de los productos mismos, empezando desde el productor y hasta el consumidor. This 3-page fact sheet was written by Massimiliano Marvasi, Max Teplitski, Andrée George, and George Hochmuth, and published by the UF Department of Soil and Water Science, November 2012.

Production Systems: Florida Greenhouse Vegetable Production Handbook, Vol 3 (HS785/CV263)

Figure 3. Young tomato plant growing in perlite-filled bagWorldwide, commercial greenhouse vegetable producers currently use numerous production systems. Among the more prevalent include lay-flat bag or upright container culture, trough culture, rockwool, vertical culture, nutrient film technique (NFT), and ground (in-soil) culture. Many modifications of these basic production systems are presently in use, and most are appropriate for Florida, except for unamended ground culture. This 8-page fact sheet was written by Dan Fenneman, Michael Sweat, George Hochmuth, and Robert Hochmuth, and published by the UF Department of Horticultural Sciences, October 2012.

Salmonella and Pathogenic E. coli in the Crop Production Environment: Potential Sources, Survival, and Management (SL375/SS576)

agricultural fieldOver the last two decades, at least a dozen major outbreaks of gastroenteritis caused by non-typhoidal Salmonella or enterovirulent E. coli have been linked to the consumption of sprouts, nuts, and fresh (or minimally processed) fruits and vegetables. These outbreaks caught scientists and the public off guard because these pathogens were not previously considered “plant-associated.” This 3-page fact sheet highlights recent discoveries that focus on the ecology of human pathogens in the crop production environment. A better understanding of how pathogens persist outside of animal hosts in agricultural water, soils, and plants will have major impacts on managing produce safety from “farm to fork.” Written by Max Teplitski, Andree George, and George Hochmuth, and published by the UF Department of Soil and Water Science, October 2012.

Fertilizer Experimentation, Data Analyses, and Interpretation for Developing Fertilization Recommendations: Examples with Vegetable Crop Research (SL345/SS548)

theoretical data showing crop response to nitrogen fertilizationFertilizer recommendations contain several important factors, including fertilizer form, source, application timing, placement, and irrigation management. Another important part of a fertilizer recommendation is the amount of a particular nutrient to apply. The optimum fertilizer amount is determined from extensive field experimentation conducted for several years, at multiple locations, with several varieties, etc. This 10-page fact sheet focuses on the research principles behind determining the optimum rate of fertilizer, including experimentation and interpreting research results for optimum crop production and quality in conjunction with minimal environmental consequences. Authors George Hochmuth, Ed Hanlon, and Allen Overman use examples from research with vegetable crops in Florida and emphasize that how one interprets the results is as important as how one conducts the research.

A Summary of N, P, and K Research with Tomato in Florida (SL355/CV236)

Tomatoes on the vineMore than 60 years worth of tomato fertilization research has been conducted in Florida. During this time, many changes have occurred in tomato production practices, including changes in cultivars and the introduction of new cultural systems, such as polyethylene mulch and drip irrigation. The research reported here covers tomato production with polyethylene mulch. Tomato crop and fertilizer management recommendations, such as plant and row spacing, have changed over time following new developments in research. This 38-page fact sheet summarizes tomato fertilization research leading to current University of Florida recommendations and summarizes needs for additional research.

Accounting for the Nutrients in Reclaimed Water for Landscape Irrigation (AE479)

water droplets mid-air in the landscapeThis 8-page fact sheet presents basic information for those using reclaimed water to irrigate lawns and landscapes. The information can serve as a guide to determine whether there is an opportunity to replace some of the fertilizer that might otherwise be applied and to offer guidance on avoiding runoff and leaching of excess nutrients.

Iron (Fe) Nutrition of Plants (SL353/SS555)

iron deficiency in tomatoIron is one of 16 essential elements for plant growth and reproduction. Most annual plants have a requirement for Fe on the order of 1 to 1.5 lb Fe per acre, compared with nitrogen (N) at 80 to 200 lb per acre. This 8-page fact sheet provides a detailed basic understanding of soil science and plant physiology for diagnosing and correcting Fe problems in plants and soils.
