This paper focuses on the economic feasibilities of using two digester designs suitable for Florida -- covered lagoons and fixed-film digesters to generate electricity for on-farm use or sales. A grant from the Florida Department of Agriculture and Consumer Services (FDACS) was used to employ the services of two consulting firms that were familiar with the design and operation of fixed-film and covered lagoon digesters. The consultants visited three dairy farms located in Florida in the winter of 2005, calculated wastewater flows (including flushed manure, milking parlor wastewater, and recycled flush water), and determined the size and other necessary aspects of the potential systems specific to each dairy farm. Estimates were developed for the quantities of biogas and electricity that would be generated by each system. The consulting firms also projected initial capital investment costs and operating and maintenance costs for each system. Retired from EDIS public website March 30, 2021.

Hemp is an annual herbaceous plant that may be grown for fiber, seed, or flowers. Starting in April 2020, the Florida Department of Agriculture and Consumer Services began accepting applications for cultivation of hemp in Florida, with the potential for building a $20–$30 billion industry in the state. The statewide UF/IFAS Industrial Hemp Pilot Project is researching aspects of agronomic production for hemp cultivation. While a few other state soil testing laboratories provide soil tests and nutrient recommendations based on research and experience, at this time no Florida-specific data on nutrient requirements and fertilization are available. This new 5-page article, written by Rao Mylavarapu, Zachary Brym, Luis Monserrate, and Michael J. Mulvaney and published by the UF/IFAS Department of Soil and Water Sciences, provides a summary of published and personal communications from different states on hemp fertilization.https://edis.ifas.ufl.edu/ss689

AbstractThe use of mobile processing units (MPUs) for pasture poultry is growing rapidly. This study compared the economic feasibility of MPUs to two processing alternatives, traditional stationary processing on-farm plants and off-farm processing facilities. Our study combined a survey of pasture poultry farmers in Georgia, Louisiana, and Arkansas with the published research. Our findings suggest that MPUs and traditional on-farm processing alternatives have a lower processing cost, but that they require a higher initial investment than the off-farm option. In addition, off-farm processing at the United States Department of Agriculture-inspected facility allows selling products for a higher price. We therefore expect, on average, a higher per-bird profit than with the other two options. However, the excess processing capacity of the MPU can make this option the most profitable.

This handbook is designed to provide a summary of the principal federal and state (Florida) laws that directly or indirectly relate to agriculture. Because these laws are subject to constant revision, portions of the handbook could become outdated at any time. The reader should use it as a means to determine areas in which to seek more information and as a brief directory of agencies that can help answer more specific questions.

In recent years plantain (Plantago lanceolata) has emerged as a potential forage for reducing nitrogen losses from dairy farm systems. However, achieving sufficient proportions of plantain in pastures to help meet target reductions in nitrate leaching presents on-farm challenges. To investigate sowing methods for establishing plantain into existing pasture to achieve high plantain populations, direct drilling was compared with broadcasting before and after grazing. Additionally, pre-graze mowing versus grazing only, and early versus late first defoliation after sowing were investigated to assess their effect on reducing competition from existing pasture. Botanical composition was determined in a small-plot study at Lincoln following summer sowing under irrigation, and from commercial dairy farms in Canterbury (irrigated) and Waikato (not irrigated). Generally, direct drilling was more effective than broadcast sowing for establishing plantain. The method of defoliation after sowing (pre-graze mowing or grazing) was not as important as timing of early defoliation in the resulting plantain populations. Early grazing, while seedlings were small enough to avoid defoliation, improved plantain establishment likely by reducing competition from the pre-existing pasture.

This handbook is designed to provide an accurate, current, and authoritative summary of the principle Federal and Florida laws that directly or indirectly relate to agriculture. This handbook should provide a basic overview of the many rights and responsibilities that farmers and farmland owners have under both Federal and Florida laws as well as the appropriate contact information to obtain more detailed information. However, the reader should be aware that because the laws, administrative rulings, and court decisions on which this handbook is based are subject to constant revision, portions of this publication could become outdated at anytime. Several details of cited laws are also left out due to space limitations. This document is FE596, one of a series of the Food and Resource Economics Department, UF/IFAS Extension. Published December 2005.

This document contains a summary of general recommendations to protect the safety of food and water in the event of a hurricane, flooding, or related natural disaster. These recommendations have been adapted from those developed under National Recommendations for Disaster Food Handling, a multi-state grant involving Cooperative Extension collaborators from Tennessee, Florida, and Missouri as well as the American Red Cross and Tennessee Department of Agriculture. Recommendations have also been included from additional up-to-date sources such as the: Centers for Disease Control and Prevention (CDC), Environmental Protection Agency (EPA), Food and Drug Administration (FDA), Florida Department of Agriculture and Consumer Services (DOACS), Florida Department of Health (DOH), Federal Emergency Management Agency (FEMA), and American Red Cross. This document is FSHN0520, one of a series of the Food Science and Human Nutrition Department, UF/IFAS Extension.

A species of scale insect new to Florida is potentially one of the most devastating pests of trees and shrubs in the state's history. The lobate lac scale, Paratachardina lobata lobata (Chamberlin) (Hemiptera: Sternorrhyncha: Coccoidea: Kerriidae), a scale insect native to India and Sri Lanka, was found for the first time in Florida in August 1999 by personnel of the Florida Department of Agriculture and Consumer Services, Division of Plant Industry (DPI) (Hamon 2001). This document is EENY-276, one of a series of the Department of Entomology, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Abstract Improved quality and efficiency of pesticide residue analysis were achieved by examining all aspects of the laboratory process. In an effort to eliminate methylene chloride hazardous waste, an acetonitrile extraction method, originally developed by the California Department of Agriculture, was modified and adopted. Sample size and solvent consumption were reduced with the new method. Custom glassware racks and disposable supplies reduced overall analysis time. Gravity-fed, solid-phase extraction simplified sample preparation and provided cleaner extracts for gas chromatographic analyses. Modifications to the method were made to achieve the ruggedness needed to maintain quality objectives during routine analysis. Instrumental improvements, including new selective detectors, retention time locking, and mass spectrometry screening for all samples, provided the laboratory with efficient, reliable, and confirmed analytical results.
