Robert Posthuma, developer of the GEOtea compost tea brewing system, has devoted the better part of his life to studying and working with fertilization and soil management. After many years of development, trial & error, and testing, Robert is proud to have the ability to present a product that holistically effects the ecosystem for the better. He travels around the world educating people on compost tea and working with them to produce a product which will best serve the customer’s need, though it’s always enjoyable to come home to rural Wisconsin where he makes his home.
