An Extensionist’s Guide to Farm and Site Visits

Marcelo Wallau, Bob Hochmuth, Tatiana Sanchez-Jones, Mark Warren, Carissa Wickens, Prissy Fletcher, and Cheryl Mackowiak

Farm and site visits are a major component of Extension work, whether as a county faculty or state specialist. They serve various purposes, such as informal check-ins, relationship building, problem solving, sharing technology, and information collection. While time-consuming, farm visits are often the most effective method for addressing problems and developing deeper connections with stakeholders (Petrzelka, Padgitt, and Windestenn, 1999). These visits provide firsthand knowledge of the issues clients face and are effective in establishing collaborations, assessing needs, understanding agricultural production systems, and validating research applications (Oakley and Garforth, 1985; Seevers and Graham, 2012). This publication explores different facets of farm and site visits, including preparation before the visit, the investigative (problem-solving) process during the visit, and post-visit procedures. Additional resources are included to support client visits and troubleshooting.

Managing Wireworms in Florida Sweet Potatoes

Robert Hochmuth, Dakshina Seal, Norman Leppla, Daniel Fenneman, Rhoda Broughton, and Anil Baniya

This publication describes current methods for managing wireworms in sweet potato. Wireworms, the larvae of click beetles, are the most damaging insect pests of those that infest the foliage and roots. Soil tillage and crop rotation can suppress populations of these root pests but adequate management requires diligent surveillance and the use of insecticides. Describes new research on managing wireworms with alternative insecticide active ingredients and entomopathogenic nematodes.

Carrot (Daucus carota) Production in the Sandy Soils of North Florida: Nitrogen Fertilization Guidelines

Morgan Morrow, Vivek Sharma, Robert C. Hochmuth, Charles Barrett, and Marina Burani-Arouca

This publication discusses carrot growth characteristics and provides nitrogen fertilizer best management practices for carrot crops growing in north Florida. The nitrogen management guidelines presented in this publication are based on multiyear field-based research conducted by UF/IFAS. Written by Morgan Morrow, Vivek Sharma, Robert C. Hochmuth, Charles Barrett, and Marina Burani-Arouca, and published by the UF/IFAS Department of Agricultural and Biological Engineering, July 2023.

Ginger, Galangal, and Turmeric Production in Florida

Paul Fisher, Rosanna Freyre, Celina Gómez, Brian Pearson, Tatiana Sanchez-Jones, Shawn Steed, Wanda Laughlin, Robert Hochmuth, Jeff Wasielewski, Deah Lieurance, Carrie Harmon, Mathews Paret, Lance Osborne, Kevin Athearn, Steven Sargent, Mengzi Zhang

Ginger, galangal, and turmeric (Figure 1) are emerging crops for Florida production. All of these plants are in the Zingiberaceae family and share most aspects of their production. This publication describes production in containers or the field under Florida conditions to help guide growers interested in ginger, turmeric, and galangal production or expanding their market. All species have been evaluated by the UF/IFAS Assessment of Non-native Plants in Florida’s Natural Areas (UF/IFAS Assessment) using the Predictive Tool (an invasion risk assessment) and all present a low risk of invasion in Florida (https://assessment.ifas.ufl.edu).

UF/IFAS Nutrient Management Recommendation Series: Carrot

Robert Hochmuth, Vivek Sharma, Thomas Obreza, and Rao Mylavarapu

Nutrient management recommendations for carrot are described according to the standard UF/IFAS recommendation format of 1) a calibrated soil test result; 2) target soil pH; 3) the "4Rs" of fertilizer management: rate, timing, placement, and source; and 4) water management factors.

Watermelon Production Budget for North Florida

Kevin Athearn, Marina Burani Arouca, Robert C. Hochmuth, Josh H. Freeman, Nicholas Dufault, Benjamin Broughton, Tatiana Sanchez, Mark Warren, Luke Harlow, and Henry T. Pittman

This publication describes a sample watermelon production budget for a spring season in north Florida. We estimate costs for fixed assets, equipment operation, labor, materials, services, harvesting and marketing. We also estimate yield and potential returns. A budget summary and sensitivity table are provided. A spreadsheet that can serve as a budget template accompanies the manuscript.

Disaster Assistance for Agriculture in Florida following Hurricane Idalia

Shivendra Kumar, Kevin Athearn, Christa Court, Angela Lindsey, Kelly Aue, Lisa Strange, Sudeep Sidhu, Joel Love, Robert Hochmuth, Erin Jones, Emily Beach, Keith Wynn, Dan Fenneman, Jay Capasso, and Eric Simonne

Multiple federal and state agencies provide assistance to qualified agricultural producers following a natural disaster, such as a hurricane. However, the programs change over time, and many producers are not aware of the programs available. The purpose of this publication is to list and briefly describe disaster assistance resources available to agricultural producers in Florida after Hurricane Idalia. To the extent that some information remains the same, this publication could provide guidance to Extension agents, nongovernmental organizations, and producers impacted by future hurricanes. The information was compiled from websites, government documents, and discussions with government agency representatives following Hurricane Idalia.

Plant Petiole Sap-Testing for Vegetable Crops

George Hochmuth and Robert Hochmuth

Various nitrate and potassium "quick-test" kits for vegetable plant sap-testing have been calibrated for use on Florida vegetables. The objective has been to find a system that growers can use in the field to help manage nitrogen (N) and potassium (K) fertilizer—especially for drip-irrigated vegetables. The following guidelines should help individuals who are currently using—or are interested in using—sap-testing. Revision by George and Robert Hochmuth published by the UF/IFAS Horticultural Sciences Department; 6 pages.
