Comparison of Soil Test Extractants for Available Soil Phosphorus in High pH Sandy Soils of South Florida
No full textThis document addresses the selection of soil nutrient extractants in high pH soils and discusses their relationship to both nutrition and fertilizer management. This document’s objective is to describe the impact of selected soil extractants on nutrient management and their ability to determine soil phosphorus availability. The target audience for this series dealing with citrus nutrition includes Certified Crop Advisers; citrus, vegetable, and sugarcane producers; fertilizer dealers; and other parties interested in crop fertilization practices. This 4-page fact sheet was written by Kelly T. Morgan and Kamal Mahmoud, and published by the UF Department of Soil and Water Science, December 2013
A Web-Based Irrigation Scheduling Model to Improve Water Use Efficiency and Reduce Nutrient Leaching for Florida Citrus
No full textSL286, a 4-page illustrated fact sheet by Kelly T. Morgan, Edward A. Hanlon, and Thomas A. Obreza, describes an easy to use web-based water-balance irrigation scheduling tool that assists growers in determining irrigation schedules that can improve water use efficiency and reduce nutrient leaching. Published by the UF Department of Soil and Water Science, May 2009.
Nutrient Management of Vegetable and Agronomic Row Crops Handbook
No full textThrough the implementation of a series of targeted cultural practices discussed in this production guide, growers should be able to reconcile economic profitability and responsible use of water and fertilizer. Topics include: proper sampling practices and test interpretations; irrigation management methods and automation; use of alternate fertilizer materials to retain nutrients in the soil but allow adequate supply for crop uptake. Use of these BMPs ensures that adequate fertilizer rates may be achieved by combinations of UF/IFAS recommended base rates and supplemental fertilizer applications. This 199-page handbook was edited by Kelly T. Morgan, and published by the UF Department of Soil and Water Science, February 2015.
