"The Root Zone Environment" a Key Factor In Controlled Environment Hydroponic Production?

 

When it comes to hydroponic vegetable production the root zone environment, including oxygen levels and root temperature, play a critical role in the success of the crop.

“For true hydroponics, which would include deep water culture and nutrient film technique (NFT), both have different oxygen profiles,” said Neil Mattson, greenhouse horticulture professor at Cornell University. “Typically with NFT, there is near saturation with oxygen because of mechanical aeration from the water recirculation that is occurring. The water that is pumped through an NFT system and is emitted by spaghetti tubing becomes essentially saturated with oxygen. This water is running across the plant roots continuously.”

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives. 

This technology is supported in part by New Technologies for Ag Extension (funding opportunity no.
