Ask IFAS: Tropical REC

Tropical REC

Tropical Research and Education Center(TREC) was established in 1929 by an act of the state legislature in what is now Miami-Dade County. Due to the region's humid subtropical climate, TREC is the only state university research center in the continental U.S. focusing on a large number of tropical and subtropical crops. Also, the area's oolitic limestone soil is unique to extreme southern Florida. In addition, the Center addresses water and environmental issues that impact crop production over a shallow aquifer and in proximity to Everglades National Park, Biscayne National Marine Park, Florida Bay and major well fields which provide drinking water to the several million people in neighboring urban areas.

Vanilla Growing in South Florida

HS1348/HS1348 by Xingbo Wu, Pamela Moon, Alan Chambers, and Jonathan CraneFebruary 26, 2024Vanilla extract is popular around the world as an ingredient in food, cosmetics, and pharmaceutical applications. The botanical source of vanilla extract is primarily the cured beans of Vanilla planifolia. The United States is the world's largest importer of vanilla beans, but domestic production is minimal. Southern Florida has a favorable growing environment for vanilla cultivation. Though currently there is no commercial production of vanilla in southern Florida, it has the potential to be a highly profitable crop in the future. This publication aims to provide basic information to growers interested in establishing a vanillery.Critical Issue: 1. Agricultural and Horticultural Enterprises

Nutrient Management Recommendations Based on Mehlich-3 Extractant for Calcareous Soils in Miami-Dade County

SS717/SL504by Yuncong Li, Qiang Zhu, Rao Mylavarapu, Kelly Morgan, Guodong Liu, Jonathan Crane, Qingren Wang, Henry Mayer, Jeff Wasielewski, Laura Vasquez, Qingchun Liu, and Teresa OlczykAugust 16, 2023This factsheet provides information about the history of soil testing calibrations and justification for recommending extraction of soil nutrients using Mehlich-3 for calcareous soils in Miami-Dade County. The dominant soils from this County have an extraordinarily high concentration of calcium resulting in high pH. This document also includes UF/IFAS approved Mehlich-3 extractant-based testing interpretations and recommendations for these soils. The purpose of this publication is to elucidate an appropriate approach for analyzing the unique calcareous soils from Miami-Dade County for plant available nutrients. The target audiences are Extension agents, agronomists at soil testing laboratories, crop advisors, growers, representatives of the state and local agencies, and others concerned about soil testing and plant analysis in Miami-Dade County.Critical Issue: 1.
