Design, Construction, and Installation of a Drainage Lysimeter for Use on Sandy, Well-Drained Soils under Turfgrass

A notch for the collection tube is made and the lysimeter is ready for pea gravel.

Using lysimeters to collect water quality samples can provide a better understanding of nutrient or other solute migration below the surface, which can inform landscape management for environmental protection. This 6-page publication presents the materials, construction, installation, and management of a specific drainage lysimeter design in a step-by-step format. Written by Jovana Radovanovic, Eban Z.

Urban Fertilizer Ordinances in the Context of Environmental Horticulture and Water Quality Extension Programs: Frequently Asked Questions

Gardener fertilizing yard. Grass, turf, broadcast spreader.

Excess nitrogen (N) and phosphorus (P) in water bodies are a leading cause of water quality degradation statewide. More than 50 Florida counties and municipalities now have formal fertilizer ordinances, which in some cases include fertilizer blackouts, or bans on the usage of N and P fertilizers during certain times of the year. This 8-page document provides information on the underlying issues of fertilizer use, with an emphasis on an urban setting, and outlines the current state of the science on urban fertilizers and water quality in Florida. Written by Michael D. Dukes, Lisa Krimsky, Mary Lusk, Laurie Trenholm, Bryan Unruh, Michelle Atkinson, and Rao Mylavarapu, and published by the UF/IFAS Department of Agricultural and Biological Engineering, February 2020.

Pastures and Forage Crops for Horses

Horse grazing bermudagrass.

Florida's unique climatic characteristics allow for forage production most of the year with a large variety of possible forage choices. Independent of the size of the operation and number of horses, good forage planning can help reduce feeding costs, environmental impacts, and nutritional disorders caused by high-concentrate feeding. With the exception of high-performance animals, horses can meet most of their nutritional needs from pasture. However, achieving this requires careful planning and implementation of a forage production and utilization program. This 9-page document discusses intake and nutrient requirements, pasture planning, forage species, and pasture management. Written by M. Wallau, E. L. Johnson, J. Vendramini, C. Wickens, and C. Bainum, and published by the UF/IFAS Agronomy Department, revised January 2019.

The Fate of Nitrogen Applied to Florida Turfgrass

The quality of Florida’s surface and ground waters is of utmost importance to the flora and fauna living in them, as their growth is directly related to the amount of nutrients in these waters. In order to make informed decisions regarding nitrogen (N) applications to turfgrass, it is important to understand the N cycle in the soil/turfgrass system. The objective of this 8-page publication is to identify and describe the sources and potential fates of N applied to Florida turfgrass. Written by T.W. Shaddox and J.B. Unruh and published by the UF/IFAS Department of Environmental Horticulture, January 2018.

Soil Testing and Interpretation for Florida Turfgrasses


John Cisar, a professor of Environmental Horticulture at the University of Florida's Fort Lauderdale Research and Education Center, is studying how turfgrass and other landscape plants can help prevent nitrogen from leaching through the soil into groundwater, Wednesday - Aug. 13, 2003. He said three years of research have shown that turfgrass is most effective in reducing nitrogen leaching and should be used in Florida landscapes. Other plants require more time to become established and slow nitrogen leaching through the soil.
Most people agree that healthy, well-maintained turfgrass is a thing of beauty. The successful growth of turfgrass is aided by having knowledge of a few basic facts concerning the nutritional requirements of turfgrasses and the properties of fertilizer and liming materials. This four-page document will help the reader understand how soil testing may be used to more efficiently manage nutrient applications for Florida turfgrasses. Written by T.W. Shaddox and J.B. Sartain and published by the UF/IFAS Department of Soil and Water Sciences, October 2017.

Nematode Management in Residential Lawns

Plant-parasitic nematodes are among the least understood and most difficult pests to manage on turfgrass in Florida. They are very small, and most can only be seen with the aid of a microscope. They use a stylet to puncture plant cells, to inject digestive juices into them, and to ingest plant fluids. The most reliable way to determine whether plant-parasitic nematodes are involved in a turf problem is to have a nematode assay conducted by a professional nematode diagnostic lab. This 6-page fact sheet was written by William T. Crow, and published by the UF Department of Entomology and Nematology.

Nematode Management on Athletic Fields

Roots of nematode-damaged turf may appear “cropped off” an inch or less below the surface.

Turfgrasses are essential components of many athletic fields, racetracks, and parks. Plant-parasitic nematodes can damage athletic fields by weakening turf root systems and causing turf to pull up during play, which can create dangerous conditions for players. To help keep turf–and athletes–healthy, this 7-page fact sheet written by William T. Crow and published by the Department of Entomology and Nematology explains how to spot and manage a nematode problem in an athletic field.

Insect Pest Management on Turfgrass

Granulate cutworm larvae.
Turfgrass is grown in many environments and for different uses, including home lawns, parks, athletic fields, cemeteries, golf courses, sod farms, pastures, and right-of-ways. The intensity of turfgrass insect management largely depends on the turf species, variety, and its intended use. This eighteen-page fact sheet describes how to manage a variety of insect pests including armyworms, bermudagrass mite, cutworms, fire ants, ground pearls, hunting billbug, mole crickets, scales/mealybugs, southern chinch bug, twolined spittlebugs, tropical sod webworm, and white grubs.

Every landscape manager has a pest management toolbox, which contains tools that represent different management strategies. People can be quick to use pesticides, but an integrated approach using multiple tools can be much safer, have longer lasting beneficial effects, and in some cases cut costs. This 5-page fact sheet will help Extension agents and specialists, lawn and landscape managers, Florida Master Gardeners, and homeowners develop long-term sustainable pest management programs using an Integrated Pest Management (IPM) framework.
