He is proficient in Portuguese. Colleagues describe him as "A number of the coffee producers that I collaborate with and have purchased coffee from over the years have engaged Sam and SoilSymbiotics to improve qualities, increase yields, reduce the effects of climate change and disease, and renovate their farms. Through his advice, my partners have been able to achieve these goals and build more economically sustainable, profitable and diversified farm systems using organic, scientific approaches built to cultivate the soil. When possible or appropriate, one of my first referrals to coffee producers seeking to improve their practices or overcome challenges posed by coffee leaf rust, climate change or the economic volatility of growing coffee in monocultures is to Sam and SoilSymbiotics.", "I've collaborated with Sam over the past several years. First as presenter at the Living Soils Symposium and now at my own vegetable farm. Sam uses science and the understanding of the bottom line of business as the foundation for his approach, while maintaining a holistic view of farming systems. Utilizing these holistic approaches, Sam propels the modern farmer onto the cutting edge of what is possible with the production of nutrient dense crops and biologically alive soils. Modern farmers have to think outside of the box to be successful and Sam is one of the most important tools to have in our toolbox of solutions.", and "I want to strongly recommend Sam Knowlton for the support he has given at this time to the Wholesum growers, we can see an excellent result before and after starting the process of managing beneficial microorganisms of the soil. He is a very professional person with wide knowledge of compost management. Regards!"
