The production systems for sugarcane include either green cane or burnt cane harvesting operations. Sugarcane in Florida is typically harvested with burnt cane mechanical harvesting, but there is a growing interest to better understand the effects of green cane harvest residue “trash blankets” on microclimate conditions for sugarcane growing on both organic and mineral soils of Florida, so the authors conducted a three-year study to determine the effects of each harvest method on microclimate within the surface soil profile and at a 10 cm height from the soil surface. Results are presented in this 4-page fact sheet written by Hardev Sandhu, Maninder Singh, Robert Gilbert, Kelly Morgan, Ronald Rice, Leslie Baucum, James Shine Jr., and Mike Irey, and published by the UF Department of Agronomy, April 2015.

Field Observations During the Tenth Microwave Water and Energy Balance Experiment (MicroWEX-10): from March 1, 2011 through January 5, 2012
For accurate weather prediction, accurate modeling of surface hydrological processes is very important. Most current models capture the biophysics of moisture and energy transport and of crop growth and development pretty well. However, model estimates of soil moisture in the root zone diverge from reality due to accumulated errors in initialization, forcings, and computation. Remotely sensed microwave observations can be assimilated into these models to improve root zone soil moisture and crop yield estimates. This 100-page report describes the observations conducted during a season-long experiment in elephant grass and sweet corn using active and passive microwave observations.

Your Farm Weather Station: Installation and Maintenance Guidelines
Weather is a prominent factor in the success or failure of agricultural enterprises, and the technology is improved and less expensive, so many farmers are installing farm-based weather stations for tracking weather conditions, scheduling irrigation, make decisions related to cold protection, and accomplish other tasks. But management decisions must be based on high-quality observations. Sensors must meet accepted minimum accuracy standards, the station must be sited properly and well-maintained.
This 5-page fact sheet provides farmers with basic guidelines for installing and maintaining a weather station. Written by Clyde W. Fraisse, George W. Braun, William R. Lusher, and Lee R. Staudt, and published by the UF Department of Agricultural and Biological Engineering, April 2015.

Sting Nematode Belonolaimus longicaudatus Rau (Nematoda: Tylenchida: Belonolaimidae)
Among the most destructive plant-parasitic nematodes to a wide range of plants, Belonolaimus longicaudatus damages plant roots. When the plants cannot take up water and nutrients from the soil, they become stunted, wilt, and with severe infestation, die. Florida is considered to be the point-of-origin for Belonolaimus longicaudatus and therefore this nematode exhibits a great deal of diversity in morphology, host preference, and genetics in our region.

Anagyrus pseudococci Girault (Insecta: Hymenoptera: Encyrtidae)
Anagyrus pseudococci is an economically important biological control agent commonly used against the vine mealybug (which infests wine grapes) and the citrus mealybug. It is a solitary, internal parasitoid and lays one egg per host, with the larva developing inside the host’s body. The wasps may be commercially reared and distributed inside mummies, and they will emerge within 1-5 days after delivery. Application involves placing a bottle containing the mummies in a dry spot of the crop and allowing the adults to emerge. This 5-page fact sheet was written by Theresa Chormanski and Ronald D.

Zombie Fly (suggested common name) Apocephalus borealis Brues (Insecta: Diptera: Phoridae)
The zombie fly is primarily a parasitoid of bumble bees and wasps in North America. In 2012, Dr. John Hafernik and his colleagus at San Francisco State University discovered that Apocephalus borealis also parasitizes honey bees. Parasitized honey bees show zombie-like behavior by leaving their hives at night and are often attracted to nearby lights where they show disoriented behavior and die in a few hours.

Health Benefits and Medicinal Value of Honey
Honey has been used for medicinal purposes for thousands of years. It is rich in sugars such as glucose and fructose, but it also contains small amounts of vitamins, minerals, amino acids, and antioxidants such as phenolic acids and flavonoids. These nutrients help to make honey a unique, natural health product. Its market niche as a health product is growing, and current research supports the potential of honey as a medicinal product. This 3-page fact sheet describes health aspects of honey deriving from the floral source and color, beneficial compounds, anti-microbial properties and anti-inflammatory properties.

Understanding Nitrogen Availability from Applications of Anaerobically Digested Beef-Cattle Manure in Florida Sandy Soil
Anaerobic digestion of livestock manure is a microbe-mediated process carried out in vessels or tanks, where the livestock wastes are digested slowly in environment absent of oxygen. The main products are biogas, anaerobically digested liquid (ADL), and solid (ADS), which can be land-applied as an organic soil amendment or a source of plant nutrients. This 4-page fact sheet provides research-based information about using anaerobically digested beef-cattle manure as an organic source of nitrogen for supplementing crop nutrition in Florida sandy soils, including initial N concentration, application timing, rate of application, and method of application.

Tree Assistance Program for Florida Citrus Greening
In September 2014, the USDA Farm Service Agency (FSA) announced additional support for commercial Florida citrus growers to manage greening, in the form of an expansion of the Tree Assistance Program (TAP). The original program assisted growers in the event the loss occurred within a single year due to a natural disaster such as a hurricane. The expanded TAP recognizes citrus greening (Huanglongbing, or HLB). The program provides growers cost-sharing financial assistance to replace trees that meet a mortality criterion within a time period of up to six years. This 4-page fact sheet describes eligibility requirements, how the program works, and how to calculate payments.

Managing Nitrogen Inputs and Outputs on a Dairy Farm
In dairy production systems, nitrogen flows through both the forage crops and the dairy cows. Forage crops use nitrogen mineralized from manure for plant growth. Harvested crops are then fed to dairy cows that, in turn, use the nitrogen for their growth and milk production. When the cows excrete a portion of the consumed nitrogen as manure the cycle is renewed. This 5-page fact sheet focuses on the forage production aspect of the nitrogen cycle at a dairy farm.

Floridian Consumer Perceptions of Local versus Organic Ornamental Plants
Horticultural consumers in Florida are interested in local and organically produced plants. But these terms can mean different things in different regions. UF/IFAS researchers conducted a survey last summer which suggests that consumers in central Florida define local as plants that are grown near where they are sold and identify the most important local benefits as product safety, quality, and community support. Organic plants are perceived as requiring fewer chemical additives and being healthier for the environment. The importance of these traits varies by plant type.

Chicken Mite (other common names: poultry red mite, roost mite) Dermanyssus gallinae (De Geer) (Arachnida: Acari: Dermanyssidae)
The chicken mite affects egg-laying hens in many parts of the world, including Europe, Japan, China, and the United States. Although Dermanyssus gallinae affects birds in many regions, it is most prevalent in European countries, where egg industry losses are estimated at $177 million per year. It is a known vector for the St. Louis encephalitis virus, as well as other illnesses, such as fowl pox virus, Newcastle virus, and fowl cholera. In the United States, Dermanyssus gallinae is rarely found in caged-layer operations and is more commonly found in breeder farms. This 3-page fact sheet was written by Ethan Carter and Jennifer L.

Biochar Effects on Weed Management
Biochar can potentially provide better conditions in the soil to increase plant growth. However, research has shown that weed species show minimal changes in germination and emergence patterns with the addition of biochar. Regardless, if biochar is used in the field it is important to monitor for changes in weed populations. This is especially important because biochar can decrease herbicide efficacy.

Sugarcane Mosaic
Mosaic’s most distinctive symptom is a pattern of contrasting shades of green, often islands of normal green on a background of paler green or yellowish chlorotic areas on the leaf blade. It had not been a problem in Florida until 1996, when it was observed on CP72-2086, a major commercial cultivar, near the intersection of Hatton Highway and US 98. Presently, because of the limited acreage of CP72-2086, the disease is only a potential threat. This 3-page fact sheet was written by P. Rott, J. C. Comstock, R. A. Gilbert, and H. S.
