Potatoes are an important crop in the United States, and Florida is ranked the 7th producer nationwide for potato production. In Florida, potatoes are mainly planted on sandy soils with low nutrient- and water-holding capacities. Nitrogen is the most limiting nutrient in these soils. Adopting efficient fertilization methods such as fertigation is imperative for minimizing leaching and improving use efficiency of nitrogen. This new 12-page article provides step-by-step guidelines for fertigation practices for commercial potato production.

This 6-page fact sheet provides information on the importance of nitrogen budgets for potato cultivation and discusses the steps in preparing the budget. It allows growers to understand the inputs, cycling, and exports of nutrients within and away from the farm, develop a nutrient budget, and analyze best management practices (BMPs) for their farm. The results will be increased N fertilizer use efficiency, increased environmental protection, and reduced economic losses associated with potato cultivation. This document will also aid county agents, environmental management advisors, and government agency staff members who help farmers improve and implement nutrient BMPs to protect water quality.

The recent emphasis on the development of vegetable production best management practices has prompted a re-examination of fertilization practices in Florida potato production in the St. Johns River watershed. The numbers provided in this 5-page fact sheet serve as a starting point for discussion about the value of using controlled-release fertilizers, which can be a win-win-win opportunity for producers, manufacturers, and regulatory agencies by helping all meet their production, business, and environmental goals. Written by Guodong Liu, Eric H. Simonne, Yuncong Li, Chad M. Hutchinson, Mark Warren, and Steven Lands, and published by the UF Department of Horticultural Sciences, October 2011.

Potato fertilization research has been conducted in Florida for more than sixty years. During this time, changes have occurred in potato production practices including new cultivars, refinements in fertilizer application timing, use of fertilizer recommendations based on soil nutrient analysis, use of nematicides, and improved weed and pest management practices. This 33-page fact sheet summarizes potato fertilization research leading to current University of Florida recommendations and summarizes needs for additional research. Written by George Hochmuth and Ed Hanlon, and published by the UF Department of Soil and Water Science, April 2011.
