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. Written by Xiangju Fu, Guodong Liu, Lincoln Zotarelli, Steven Sargent, Kati Migliaccio, and Yuncong Li, and published by the UF/IFAS Horticultural Sciences Department.

Flooding is a major risk for commercial vegetable production in south Florida, especially in the south Dade County area. Flooding causes oxygen deficiency, or hypoxic stress, causing the plants to produce less energy. This shortage in energy prevents the absorption of nutrients like nitrogen, phosphorous, and potassium. This four-page fact sheet discusses several different management practices for overcoming flood damage, including the use of nitrogen and potassium fertilizers, oxygen fertilizers, growth regulators, and fungicides. Written by Goudong Liu, Yuncong Li, and Xiangju Fu, and published by the Soil and Water Science Department.
Fertilization plays a critical role in tomato production across the state of Florida. However, appropriate fertilization management depends on four major components (4Rs): right source, right rate, right placement, and right timing. Farming practices that follow the 4Rs can provide nutrients for optimal tomato productivity while minimizing the risk of nutrient losses and adverse environmental effects, both of which are important to the development of agricultural sustainability. This 6-page fact sheet discusses the 4Rs as well as conventional dry source fertilizers, controlled-release or slow-release source fertilizers, and liquid source fertilizers. Written by Qingren Wang, Guodong Liu, Kelly Morgan, and Yuncong Li, and published by the UF Department of Horticultural Sciences, October 2015.
