Who We Are
We are professional nutrient managers, agronomic advisors, and environmental stewards.
Natural Fertilizer has been helping Midwestern farms add natural fertility to their operations for almost two decades. Founded in 2007 by Abe Sandquist, Natural Fertilizer Services emerged from years of experience with the USDA Natural Resources Conservation Service. Through developing Nutrient Management Plans, Abe discovered that many agricultural producers were unaware of the value locked in their organic waste products—value that professional guidance could unlock. Today, our team of agronomists and application specialists helps crop and livestock producers optimize these resources through precise handling and application services. We ensure compliance with Clean Water Act regulations while creating economic opportunities that benefit farms, communities, and the environment.
