L.E.A.D Academy

Welcome to L.E.A.D Academy, our education platform designed to share information with our growers on agronomy technologies, product development research, local and national economic data, and more. Learn from our internal experts, and other industry professionals for the latest, unbiased agronomy intel.

Over the past 50 years, Liqui-Grow has invested heavily in agronomy research to develop cutting edge products that achieve profitable high yields. We have historically shared our insights with local growers, and now plan to expand that effort.

“They bring cutting edge knowledge to my operation that I can use to directly impact yields and ultimately the gross profit per acre. They are the expertise that I need to be a better farmer.”
