What Crop Services International does

Crop Services International (CSI) is a Michigan-based, privately held agricultural company that provides soil testing, agronomic consulting, and a broad catalog of biological and non-toxic agricultural products to growers throughout North America. The firm traces its operational roots to 1971, when founder Dr. Phil Wheeler began an organic farming operation near Vestaburg, Michigan; the current corporate entity was consolidated in 2014 when Dane Terrill and Nancy Essex merged their Flowerfield Enterprises with CSI, making Flowerfield the parent. CSI serves sustainable, biological, organic, biodynamic, and quantum-agriculture-oriented customers, with product and service offerings spanning biological inoculants, biological stimulants, bulk minerals, compost tea brewing systems, cover crops, dry and liquid soil amendments, minerals-and-microbes combinations, quantum-agriculture devices, and educational publications including the co-authored "The Non-Toxic Farming Handbook."

The company's core technical proposition is its dual soil testing methodology, which combines standard Cation Exchange Capacity (CEC) analysis with a LaMotte water-soluble extraction, supplemented by electronic scanning used to prescribe crop inputs — a combination CSI positions as differentiated from single-test soil labs. CSI monetizes through four primary streams: direct product sales via its e-commerce storefront and 800-number phone desk (one-time/perpetual license pricing across SKUs ranging from $12 to $1,500+), soil and plant tissue testing (repeat/recurring lab revenue), hourly personal consulting at $40–$75, and one-time sales of educational media. Distribution is predominantly direct-to-grower with multi-state FOB shipping origins (MI, UT, OH, TX, NM, MT, NV, IA, MO, ON, WA); marketing runs through a quarterly Grower Grazier newsletter, conference presence at ACRES ECO-Ag University and the Soil Health and Plant Nutrition Conference, a Facebook page, and the published handbook/DVD catalog. Multiple products carry NOP and OMRI organic-production certifications.
