About Us

Geoponic has a simple mission: To provide the highest quality seed and recommendations to improve the profitability of our customers throughout East Central Indiana.

For seven decades and three generations, Geoponic Enterprises has been serving the farming community of East Central Indiana.  Starting with Delaware County farmer Marion Russell selling Funk's G-Hybrid, Geoponic has been a business of farmers working with farmers.

Combining the latest research and technology with the knowledge that can only come from operating their own farms, the team at Geoponic knows that good seed, good treatment, andgood planning can be made great when paired with good advice.  That's why they don't sell anything they haven't tested on their own farms.

They're reliable, knowledgeable, and driven by commitment to integrity and trust.

 Jake Mitchell, Accounts Manager

Jake joined the Geoponic team in December 2011, and quickly became an indispensable resource in office.  With an associate's degree in Computer Aided Drafting, Jake worked as a design engineer for 13 years before getting back to his passion: the farming industry.  He grew up on a cattle and grain farm, and was a 10 year 4-H member.  Jake handles the mapping and prescriptions for Geoponic, and manages the office and accounts.  Jake lives in Delaware County with his children Izabella and Isaac.



Joe Russell, Founder

Joe is a sixth generation Indiana farmer who is dedicated to promoting and advancing agriculture.  A 1974 graduate of Purdue University in civil engineering, Joe worked on the Trans-Alaska Pipeline before returning to his family farm in 1976.  Joe's father Marion started selling seed in the 1950's, so it was natural for Joe to sell seed, too.  Joe lives in Delaware County with his wife Sharon, where they raised their three children.
