| Anaerobic Digesters for Manure Management for Livestock Operations Livestock wastes can be important sources of nutrients for crops, but manure must be managed properly to prevent loss of nutrients to the environment in air or ground and/or surface water. Stabilization of manure is important prior to successfully recycling the organic material back to arable lands. Methods for stabilizing livestock wastes include composting, aerobic digestion, anaerobic digestion, lime stabilization, and heat drying. The stabilization process reduces the organic matter and water contents, unpleasant odors, concentrations of pathogenic microorganisms, and weed seeds. Anaerobic digestion (AD), which is the topic of this fact sheet, also results in the production of renewable energy in the form of methane-rich biogas. This 10-page fact sheet informs farmers and Extension agents about types of anaerobic digester systems used in the United States with various manure-handling systems. It points out digester systems currently being used in Florida and the benefits of managing livestock manure with a digester system. Written by Rishi Prasad, George Hochmuth, and Ann C. Wilkie, and published by the UF Department of Soil and Water Science, March 2014. | |

| Cattle Fencing BMP Can Reduce Phosphorus Loads from Florida Ranches BMPs are an important tool in helping the state and individual landowners protect and enhance state’s waters. Given the water quality issues facing Lake Okeechobee and other sensitive water bodies, the importance of BMP implementation has increased since their official establishment as part of the FWRA. In order to ensure that BMPs are reducing nutrient loadings, on-farm research is needed to verify BMP effectiveness. A four-year study was conducted to evaluate the effectiveness of the cow/calf stream fencing BMP. The study concluded that the BMP did reduce the amount of P being discharged from the ranch. This BMP should continue to be included in the cow/calf BMP manual, and, hopefully, its widespread implementation will help the state in meeting its TMDLs. This 3-page fact sheet was written by Sanjay Shukla, Wendy D. Graham, Alan Hodges, and James M. Knowles, and published by the UF Department of Agricultural and Biological Engineering, May 2014. | |

| Bush Snapbean Production in Miami-Dade County, Florida Miami-Dade County is the primary production region for fresh-market bush snapbeans with 57% or 18,696 acres of the Florida bean acreage. Production costs vary from $16.53 to $21.87 per 30 lb. bushel or $4,046 to $4,711 per acre. Acceptable yields range from 185 to over 300 bushels per acre. Snapbeans produced in Miami-Dade County are sold nationwide for the fresh market starting just before Thanksgiving and continuing through the winter and spring months. This 9-page fact sheet was written by S. Zhang, D. Seal, M. Ozores-Hampton, M. Lamberts, Y. Li, W. Klassen, and T.

| How to Determine Run Time and Irrigation Cycles for Drip Irrigation: Tomato and Pepper Examples Even though drip irrigation is more efficient than the other irrigation methods, proper system management is crucial if that increased efficiency is going to result in water savings and a viable crop. One important aspect of drip irrigation management for crop success is irrigation scheduling, which includes determining both how much and when to irrigate. The grower can use several different methods to help develop a suitable irrigation schedule. Proper scheduling needs to be implemented to take full advantage of the increased drip irrigation efficiency. Two examples are presented in this 5-page fact sheet for tomatoes and peppers, which are two important vegetable crops in Florida, to demonstrate the use of reference evapotranspiration and crop coefficients in developing a drip irrigation schedule. Written by Sanjay Shukla, James M. Knowles, and Niroj K. Shrestha, and published by the UF Department of Agricultural and Biological Engineering, April 2014. | |

| Soil pH Management for Optimum Commercial Fruit Production in Florida Soil pH is one of the most important soil chemical properties and affects nutrient bioavailability and microbial activity. The purpose of this article is to provide an overview for faculty, crop consultants, crop advisors, fruit growers, and students who are interested in fruit production. The crop response to soil pH varies due to crop genetic diversity. Soil pH determines nutrient bioavailability and hence fruit growth, yield, and quality.

| Southern Highbush Blueberry Cultivars from the University of Florida Many improved southern highbush cultivars have been developed by the University of Florida breeding program since the initial releases of ‘Sharpblue’, ‘Flordablue’, and ‘Avonblue’ in the mid-1970s. Today there are more blueberry cultivar choices available for Florida growers than ever before, but in every case, cultivar selection involves weighing the advantages and disadvantages of a cultivar relative to the grower’s needs. Unfortunately, there are no perfect cultivars suited for every location and management system. This 10-page fact sheet categorizes southern highbush cultivars into four groups: major cultivars, secondary cultivars, new options, and historical cultivars. Proper cultivar selection is critical to a successful blueberry enterprise, and growers should seek information from multiple sources, including their local county Extension office. Written by J.G. Williamson, J.W. Olmstead, G.K. England, and P.M. Lyrene, and published by the UF Department of Horticultural Sciences, April 2014. | |

| University of Florida Potato Variety Spotlight: 'Elkton' 'Elkton' is a white-flesh potato variety suitable for chipping directly from the field. 'Elkton' was selected from the USDA-ARS breeding program in Beltsville, Maryland, by Dr. Haynes in 1997. In 2003, seed of 'Elkton' was made available for field evaluation under Florida growing conditions. In 19 trials conducted between 2003 and 2012, 'Elkton' yielded 111% in comparison with 'Atlantic'. In these trials, 'Elkton' demonstrated resistance to internal heat necrosis and hollow heart, which are common tuber physiological disorders under high-temperature growing conditions.

| Mole Cricket IPM Guide for Florida Mole crickets can become serious pests of turfgrasses, pastures, and vegetable seedlings. The first step in determining if you have a mole cricket problem at a site is to compare the existing damage to pictures of known mole cricket damage. If the damage is likely caused by mole crickets, specimens should be obtained and the pest identified. You then should determine if the number of mole crickets is great enough to cause an unacceptable level of damage and decide what control measures should be used. Eventually, a long-term, sustainable integrated pest management (IPM) program should be established. This 20-page guide will help you identify mole cricket infestations and manage them effectively and economically while minimizing environmental impacts. Written by C. R. Kerr, N. C. Leppla, E. A. Buss, and J. H. Frank, and published by the UF Department of Entomology and Nematology, May 2014. | |

| Candidate Species for Marine Ornamental Aquaculture: French Grunt, Haemulon flavolineatum Grunts (family Haemulidae) are some of the most economically and ecologically important fishes found throughout the world. Their common name refers to the characteristic grunting sound they make when they are agitated and during courtship. Many species of grunts are popular in public and private aquariums due to their schooling behavior and bright colors that create interest in aquarium exhibits. The French grunt has recently been identified as a candidate species for aquaculture due to its popularity in aquarium displays and the development of culture protocols.

| Florida MarketMaker and Florida Food Connect: Using E-commerce to Enhance Seafood Marketing in Florida While the state and many non-profit organizations provide information to the Florida seafood and aquaculture industry to help them market their catch, they offer few resources facilitating e-commerce. As a business tool, e-commerce can help expedite the buying and selling of seafood products among consumers, producers, and other businesses within the food industry value chain. E-commerce is a new promotional strategy producers can use to improve their marketing efficiency. For example, the affiliated websites Florida MarketMaker and Florida Food Connect are designed to enhance the online presence for the Florida seafood industry. Web portals such as these increase the visibility of seafood businesses by allowing dealers to create a searchable online profile attracting more customers seeking locally sourced seafood. This 6-page fact sheet was written by Charles M. Adams and William Barker, and published by the UF Department of Food and Resource Economics, May 2014. | |
