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. Bean, and Alexander J. Reisinger, and published by the UF/IFAS Department of Agricultural and Biological Engineering, February 2021.
Calcium is the dominant cation in all soils of agronomic importance. This 3-page document will explain the function of Calcium in turfgrasses, describe situations where applications would or would not be of value in turfgrass management, and identify calcium sources. Written by T. W. Shaddox and published by the UF/IFAS Environmental Horticulture Department, March 2018.
Soluble magnesium (Mg) is often applied to turfgrasses in both granular and foliar forms, and is therefore essential to understanding the function of Mg in the plant, the dynamics of Mg in the soil, and the forms of Mg fertilizers. This 3-page document discusses the function and forms of magnesium in turfgrasses. Written by T. W. Shaddox and published by the UF/IFAS Environmental Horticulture Department, March 2018.
Golf course nutrient management programs commonly include application of both nitrogen and potassium. These macronutrients are required by turfgrass in greater quantities than any other element except carbon, hydrogen, and oxygen. This two-page fact sheet explains the Nitrogen to Potassium ratios that are best for golf courses. Written by T.W. Shaddox and J.B. Unruh and published by the Environmental Horticulture Department.
Tissue analysis offers a precise estimate of a plant’s nutritional status at the time of sampling. Nutrient deficiencies can be detected with tissue analysis before visual symptoms appear. This three-page fact sheet describes the importance of tissue testing and how to interpret the results. Written by T.W. Shaddox and published by the Environmental Horticulture Department.
This 8-page fact sheet written by Adam Dale and published by the UF Department of Entomology and Nematology in February 2017 describes the types of scale insects and mealybugs that can become pests in turf, explains the damage they do, and lists management techniques to control them.
