Groundcovers Influence Citrus Yield and Water Use

Jim Rogers Irrigation, Production, Tip of the Week

By Sandra M. Guzmán In Florida citrus, black fabric mulch groundcovers have been used for the control of the invasive Diaprepes abbreviatus (root weevil). However, these groundcovers can also serve as a best management practice (BMP) to optimize tree water uptake and maintain nutrients around the root system. A three-year University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …

What Southeast Citrus Growers Should Be Watching For

Jim Rogers Irrigation, Pests, Weather

A prolonged dry spell across the Southeast should have citrus growers ensuring their young trees are properly irrigated. But Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautions growers about applying too much water. “The real young trees don’t have much of a root system, of course. It has been pretty dry. But you don’t want …

Assessing the Safety of a Water Distribution System

Jim Rogers Irrigation, Regulation, Tip of the Week

By Taylor O’Bannon, Matt Krug and Michelle Danyluk The U.S. Food and Drug Administration recently proposed changes to the pre-harvest Agricultural Water (Subpart E) section of the Food Safety Modernization Act Produce Safety Rule (PSR). Removing the annual water distribution system inspection is not one of the proposed changes. Rather, water testing for generic E. coli and developing a microbial …

Achieving Water and Nutrient Efficiency

Jim Rogers Irrigation, Nutrition, Research

University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers emphasized the importance of efficient irrigation and nutrient management at a workshop earlier this month at the Citrus Research and Education Center in Lake Alfred. In Florida, the citrus industry accounts for about 30% of irrigated cropland acreage, reported UF/IFAS researcher Alisheikh Atta. Worldwide, the agriculture industry consumes about …

Irrigation and Nutrient Management BMPs

Ernie Neff BMPs, Irrigation, Nutrition

A Citrus Expo presentation about best management practices (BMPs) focused on what growers should be doing now in their irrigation and nutrient management programs. The presentation noted that current BMPs were developed prior to HLB’s discovery in Florida in 2005, and that studies are underway to revise the citrus BMPs for nitrogen and phosphorus. The presentation was created by University …
