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.

Luffa: an Asian Vegetable Emerging in Florida

The fruit of angled luffa have a longer shelf life and are more tolerant to shipping than those of smooth luffa. The angled luffa is more popular in Florida's commercial farms for Asian vegetable crops. Credits: Guodong Liu, UF/IFAS

Luffa is the genus name of several tropical and subtropical plants in the cucumber family. Alternatively spelled “Loofa” or “Loofah,” the name is derived from the plant’s use as a material for sponges and dish cloths for bathing and cleaning dishes. This six page fact sheet describes the two types of Luffa, how to cultivate them, and what they can be used for.

Smartirrigation Apps: Urban Turf

Figure 1.  Login and registration screens for the Smartirrigation Turf app. Credit: J. H. Debastiani AndreisWe developed an app called Smartirrigation Turf to provide an easy-to-use mobile tool that delivers information to improve irrigation scheduling for urban turf. Using the app instead of a set time-based schedule for irrigation, homeowners and others can provide irrigation amounts to turf that more closely match water needs. This version of the app is applicable in Florida and Georgia and is available to download in the Apple App Store and Google Play Store. This 5-page fact sheet was written by K. W. Migliaccio, J. H.

Using Tensiometers for Vegetable Irrigation Scheduling in Miami-Dade County (ABE326/TR015)

Figure 1. Example of a tensiometer's vacuum gauge.A tensiometer is a simple and relatively inexpensive tool that can be used to schedule irrigation in Miami-Dade County vegetable crops. Tensiometers continuously measure soil water potential or tension. If the tension in the soil is high, plants have to use more energy to extract soil water. If tension in the soil is low, then plants have lower energy requirements to extract soil water. This 6-page fact sheet was written by Kati W. Migliaccio, Teresa Olczyk, Yuncong Li, Rafael Muñoz-Carpena, and Tina Dispenza, and published by the UF Department of Agricultural and Biological Engineering, December 2012.
