Our consulting process employs a principle based framework to transfer knowledge and increase the capacity of a wide range of farmers, growers, agronomists and organizations. 


We translate complex data points across mineral plant nutrition, soil microbiology, crop rotations, and plant physiology into a practical, farm specific program that empowers our clients with the understanding and support to optimize crop production and improve longterm agro-ecosystem health.

Clients in our consulting program learn how to ask better questions, analyze complex data, think holistically, and make better real time decisions. 

As a result, our clients achieve higher quality crops, better yields, increased profits, and experience ever increasing soil health. 

Led by Sam Knowlton, our principle crop consultant,  we are currently working with clients throughout the U.S. and Latin America.

Sam is a true professional. He helped us develop a plan that cut our input costs by over 50% while positively affecting overall yield and plant health. We are looking forward to working with him on future projects. He is a rare find in the world of consultants.

“For the past several years I have had the privilege of working with Soilsymbiotics on an ecological restoration and sustainable farming project. I have had the opportunity to witness the integrity of their methods and its value to the soil directly. The results have repeatedly surpassed anything I previously had understood was possible. The way the soils have responded to the applied methodology and then the nutritional quality and flavor of the food we have been producing has been astonishing. This is an expression of a very high and beneficial science, which Mr. Knowlton administers with unassuming care and humility.”

In terms of return on time and money investment in a challenging environment I could not have imagined a more efficacious and literally fruitful approach with better results than we achieved using the systems and biological applications provided by Soilsymbiotics, and with the expertise of Sam Knowlton. Even the long time farmers of this area have expressed admiration and respect for the return to productive health of this heritage orchard, and I personally am grateful for the help and advice.

After listening to Sam’s inspiring keynote speech it was clear he is on the cutting edge of agriculture. Since then, our collaboration on multiple projects has gone smoothly and produced results. Sam’s breadth and depth of knowledge is a true asset to the nutrient dense ag industry.
