Nutrient Deficiency Symptoms of Woody Ornamental Plants in South Florida

Timothy K. Broschat

Although about 16 elements are required for normal plant growth, only a few of these elements are commonly deficient in Florida landscape plants. The purpose of this document is to describe and illustrate typical symptoms for common nutrient deficiencies in trees and shrubs grown in south Florida landscapes.

Quantifying Impacts of Fertilizer Workshops on Nitrogen Leaching and Subsequent Economic Impacts: A Case Study

Alexander J. Reisinger and Tina McIntyre

The goal of this new 8-page document is to demonstrate a scientifically based approach to estimating the water quality and subsequent economic benefits of UF/IFAS Extension programming related to nutrient management in residential landscapes. It also provides a sample impact statement that could be used by UF/IFAS Extension Agents as they compile the effectiveness of their program(s). Written by Alexander J. Reisinger and Tina McIntyre and published by the UF/IFAS Department of Soil and Water Sciences.

Effects of Urban Fertilizer Ordinances on Water Quality

Alexander J. Reisinger, Michael D. Dukes, Basil V. Iannone III, J. Bryan Unruh, and Samuel J. Smidt

Originating from environmental or humans sources, too much nitrogen (N) and/or phosphorus (P) in water bodies can degrade water quality. In an attempt to reduce the contribution of human sources of N and P to local waters, urban fertilizer ordinances have been adopted in at least 35 counties in Florida and 97 additional Florida municipalities. Despite this work, the efficacy of fertilizer ordinances are debated by end users. The purpose of this publication is to summarize a peer-reviewed, scientific article that investigated impacts of fertilizer on long-term water quality trends in Florida lakes (Smidt et al. 2022) and is intended to be used by UF/IFAS Extension faculty and/or regulatory officials considering adopting or modifying an urban fertilizer ordinance. We encourage green industry professionals and concerned community members to share the effectiveness of fertilizer ordinances.

Fertilization of Field-Grown and Landscape Palms in Florida

Timothy K. Broschat

Palms growing in Florida landscapes or field nurseries are subject to a number of potentially serious nutrient deficiencies. These deficiencies are described and illustrated in document ENH1018. Prevention and treatment of these deficiencies is the subject of this document. Chemical symbols used in this document are as follows: N=nitrogen, P=phosphorus, K=potassium, Mg=magnesium, Ca=calcium, Mn=manganese, Fe=iron, B=boron, Cu=copper, Zn=zinc.
