UF/IFAS Extension Greenhouse Training Online adds bilingual video content

GAINESVILLE, Fla. — For several years, UF/IFAS Extension has offered online certification courses in greenhouse management, with more than 650 growers completing the courses in 2019. The Greenhouse Training Online program recently expanded to launch a new YouTube channel (tinyurl.com/UFGTO).

New videos in English (youtube.com/watch?v=IsFzkLIqI2s) and Spanish (youtube.com/watch?v=345jZai-Ud8) walk viewers through the process of petiole sap testing with the guidance of Tatiana Sanchez, UF/IFAS Extension Alachua County commercial horticulture agent.

Nitrate and potassium meters are effective tools for growers to do onsite testing of nutrient levels in the sap of greenhouse crops, Sanchez explained. The meters can also be used as a quick check of nutrient level in the fertigation solution, along with pH and electrical conductivity, to make sure that nutrient level is on track.

“We hope that growers who watch these videos adopt sap testing as a regular best management practice in order to meet their maximum crop potential,” Sanchez said.

The videos also include links to fact sheets available via the UF/IFAS Extension database, EDIS. Interpretive guidelines at edis.ifas.ufl.edu/ep081 explain needs for major crops such as tomato, pepper, cucumber and strawberries.

The resources are included in upcoming Greenhouse Training Online courses for growers on nutrient management and hydroponic vegetable production (hort.ifas.ufl.edu/training). More videos are set to be released in the coming weeks.
