¿Es la industria de cáñamo industrial rentable en el futuro de Florida?

Trent Blare, Trent D. Blare, Martha Rivera, Fredy H. Ballen, Zachary Brym, Victor Contreras, andVictor Contreras

El creciente incremento de la competencia extranjera e incidencia de plagas ha hecho que muchos agricultores de Florida se pregunten acerca de la rentabilidad de cultivos tradicionales como tomate, cítricos y aguacate. El cáñamo industrial se presenta como una alternativa viable para estos productores desde que, en el año 2018, la ley agrícola permitió su producción. Para ayudar a la industria a madurar es necesaria una mejor coordinación entre los reguladores, procesadores, instituciones financieras, programas de investigación y Extensión, y el sector de venta minorista para crear confianza, así como ajustar políticas y procedimientos para disminuir el costo de transacción a lo largo de la cadena de suministro; con esto se podría asegurar que los productores, industria relacionada y consumidores se beneficien de este mercado emergente. En el presente artículo se examina la cadena de valor del cáñamo enfocada en las oportunidades de mercado en Florida.

Low-Maintenance Landscape Plants for South Florida

Cliff G. Martin, Jody Haynes, John McLaughlin, Laura Vasquez, Adrian Hunsberger, and Zachary Brym

This publication was originally developed to help answer requests from participants of the Florida Yards & Neighborhoods program in Miami-Dade County, now Florida Friendly Landscaping TM (FFL), for a list of landscape plants suitable in south Florida and has become a critical reference for the county. The resulting list includes over 330 species of low-maintenance plants. For each species, we provided the common and scientific names, family, size, light preference, salt tolerance, establishment status, invasive status and potential, and other useful characteristics.

Is a Viable Hemp Industry in Florida’s Future?

Trent Blare, Trent D. Blare, Martha Rivera, Fredy H. Ballen, andZachary Brym

Disease and foreign competition have made many growers question the viability of traditional commodity crops such as tomatoes, citrus, and avocados. Industrial hemp appears to be an attractive alternative, as the 2018 Farm Bill permitted its production. Florida has followed several other states in approving permits in 2020 to allow production of industrial hemp. Markets for industrial hemp products were promising in the first years of production, but market prices started to decline dramatically in 2020 with many growers unable to sell all their product. In this publication, we examine the hemp value chain with a focus on opportunities in the Florida market. Better coordination between regulators, processors, financial institutions, research and Extension services, and the retail sector to build confidence, harmonize policies, and lower transaction costs would help the industry flourish and ensure growers, consumers, and hemp-related enterprises can benefit from this emerging market.
