Biosolids are the liquid, semisolid, and solid fractions of the treated waste stream from a domestic wastewater treatment facility (WWTF). On August 29, 2010, the Florida Department of Environmental Protection (FDEP) formally adopted its rule for the management of wastewater biosolids, Chapter 62-640, Florida Administrative Code (F.A.C. 2010). This 6-page fact sheet from the Florida Biosolids series covers applicability of the rule, the intent of Chapter 62-640, F.A.C., land application requirements, biosolids storage, cumulative application limits, setback distances, pH, soil depth, runoff prevention, additional application site restrictions for Class B biosolids, NMPs, and special geographic areas.

Practices to Minimize Flooding Damage to Commercial Vegetable Production
Flooding is a major risk for commercial vegetable production in south Florida, especially in the south Dade County area. Flooding causes oxygen deficiency, or hypoxic stress, causing the plants to produce less energy. This shortage in energy prevents the absorption of nutrients like nitrogen, phosphorous, and potassium. This four-page fact sheet discusses several different management practices for overcoming flood damage, including the use of nitrogen and potassium fertilizers, oxygen fertilizers, growth regulators, and fungicides. Written by Goudong Liu, Yuncong Li, and Xiangju Fu, and published by the Soil and Water Science Department.

Spotted Wing Drosophila Drosophila suzukii Identification, Ecology, and Management
Spotted wing drosophila (SWD) is a tiny invasive fruit fly pest of small fruits. It has been found infesting fruits in Europe and North and South America. Since its first capture in California in 2008, SWD has established populations throughout the United States in over 47 states. This trifold brochure written by Lindsy Iglesias, Teresia W. Nyoike, and Oscar E. Liburd and published by the Entomology and Nematology Department describes how to identify and monitor these tiny pests and explains a few strategies to control them and limit the damage they cause to fruit crops.

Implementing the Four Rs (4Rs) in Nutrient Stewardship for Tomato Production
Fertilization plays a critical role in tomato production across the state of Florida. However, appropriate fertilization management depends on four major components (4Rs): right source, right rate, right placement, and right timing. Farming practices that follow the 4Rs can provide nutrients for optimal tomato productivity while minimizing the risk of nutrient losses and adverse environmental effects, both of which are important to the development of agricultural sustainability. This 6-page fact sheet discusses the 4Rs as well as conventional dry source fertilizers, controlled-release or slow-release source fertilizers, and liquid source fertilizers. Written by Qingren Wang, Guodong Liu, Kelly Morgan, and Yuncong Li, and published by the UF Department of Horticultural Sciences, October 2015.

Pest Identification Guide: An Introduction to Thrips
Tiny insects called thrips are difficult to see with the unaided eye but cause very obvious and sometimes ruinous damage to the flowers, buds, and fruit of many important crops. This two-page guide asks and answers the key thrips questions that allow growers to distinguish between chilli thrips, common blossom thrips, and Western flower thrips to more effectively battle against these destructive pests. What does it look like? What is its life cycle? Where is it found? What type of damage does it cause? And, most importantly, who are its natural enemies? Use this guide to help you identify thrips so that you can take effective steps to control them and limit the damage they cause.

Improving the Precision of Blueberry Frost Protection Irrigation
In Florida, early-ripening southern highbush blueberry cultivars allow growers to take advantage of high prices in the early market before other states can compete with higher volumes of berries sold at lower prices. That advantage comes with a vulnerability, however, because frosts can reduce gains. Florida growers rely on strategies like cold protection irrigation to reduce their risk of loss due to cold damage. This 9-page article by Tatiana Borisova, Tori Bradley, Mercy Olmstead, and Jeffrey Williamson describes a UF/IFAS study comparing precision cold protection irrigation to uniform cold protection irrigation to estimate the potential savings in diesel costs and water withdrawal volumes associated with the two practices and help protect Florida’s valuable and vulnerable blueberry harvest. Published by the Food and Resource Economics Department in November 2015.

Understanding Nitrogen Transformations and Cycling for Sweet Corn Production in Sandy Soils
Because sandy soils have low water and nutrient-holding capacities and Florida experiences high rainfall periodically, optimizing fertilizer use efficiency for sweet corn production is challenging. The preparation of nitrogen budgets and the implementation of effective management strategies can help farmers overcome these obstacles. This 4-page fact sheet discusses major concerns which call for nitrogen management in sweet corn production, nitrogen budget preparation and interpretation, and important differences between farm-gate and soil system budgets.

Black Scale Saissetia oleae (Olivier, 1791) (Insecta: Hemiptera: Coccoidea: Coccidae)
The black scale is an important pest of citrus and olive trees. Originally from South Africa, this scale is now distributed worldwide. In Florida, black scale is found on citrus, cultivated olive, avocado, and many popular landscape plants. It is likely that black scale, like many invasive pests, was imported to the United States on infested nursery plants. Based on their small size and the unique life history of scale insects, these insects are difficult to detect and control. This 4-page fact sheet was written by Morgan A. Byron, Jennifer L. Gillett-Kaufman, and Sandra A. Allan, and published by the UF Department of Entomology and Nematology, March 2015. (Photo credit: Lyle Buss, UF/IFAS)
