Organic Growing Media: How Can it Affect the Health of My Transplants?

About the Webinar

Organic vegetable farmers often use growing media to produce transplants for field and high tunnel production. In this session we will share results of research comparing seedling performance of tomato and cucurbit seedlings in commercially available organic growing media. How does the plant performance relate to the chemical and physical characteristics of the growing media? How do added organic fertilizers influence the seedling growth? How do the different growing media influence the microbes in the plant rhizosphere, and what could that mean for health of the seedling? In addition, we will provide an overview of organic growing media listed by OMRI. We expect this webinar will help growers better evaluate and manage growing media for high quality transplant production.

eXtension posts publicly our events to two calendars - the eXtension Foundation Member Calendar and the Opportunities for Cooperative Extension Calendar.  All other events coming from across Cooperative Extension are posted to the Learn Calendar or to one of the regional calendars. All calendars populate to the same main calendar on Connect Extension. To tell the difference between what events are posted to what calendars easily, you'll see the name of the calendar posted above the title of the event if you scroll to the top.
