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.
La Grama St. Augustine para Patios de Florida
La grama o césped St. Augustine está muy adaptada a las zonas calurosas y húmedas (subtropicales) del mundo. Se cree que es nativa de las regiones costeras del Golfo de México y del Mediterráneo. St. Augustine es la especie de grama más usada en Florida. This is the Spanish-language version of ENH5/LH010, St. Augustinegrass for Florida Lawns. St. Augustinegrass is the most commonly-used lawn grass in Florida. This 10-page document describes its cultivation and management for Florida lawns. Written by L. E. Trenholm, J. B. Unruh, T. W. Shaddox, C. Balerdi, and H. Mayer and published by the UF/IFAS Department of Environmental Horticulture, January 2018.
Iron for Florida Turfgrasses
Iron (Fe) is commonly applied to enhance turfgrass color. Understanding the dynamics of Fe both in the plant and in the soil could greatly enhance your nutrient management programs. The objective of this 4-page publication is to explain the function of Fe within the plant, describe the Fe sources available for turfgrasses, and identify which forms of Fe are most effective in improving turfgrass quality. Written by Travis Shaddox and J.B. Unruh and published by the UF/IFAS Department of Environmental Horticulture, January 2018.
Joewood (Jacquinia keyensis): Identification and Uses
Jacquinia keyensis, known commonly as joewood, is listed as a threatened species by the state of Florida, and is most commonly found in the Florida Keys. This 8-page document discusses the identification and uses of joewood. Written by Stephen H. Brown, Marc S. Frank, and Andrew K. Koeser and published by the UF/IFAS Department of Environmental Horticulture, January 2018.
Sampling Palms for Lethal Yellowing and Texas Phoenix Palm Decline Phytoplasmas
In Florida, palms are an economically important group of trees in the nursery and landscaping industries. Phytoplasma diseases of palms are a major concern because they infect a wide variety of these valuable ornamental palms, and they are lethal. Once symptoms appear, trees begin to decline, frequently rapidly, and can die in as few as 3 to 5 months. This 4-page fact sheet written by Brian W. Bahder and Ericka E. Helmick and published by the UF/IFAS Department of Entomology and Nematology describes how to sample palms for disease and how to submit samples to the Vector Entomology Lab. Includes a table listing equipment and supplies and protocol for sampling palm trunk tissue.
