Our Team

God. He has blessed us with an amazing community to live in that we all get to call home. At Tonner Precision Services, we are excited to learn, serve, and build relationships with other growers in northern Indiana, southern Michigan, northern Ohio, and more. As a family-oriented business, we strive to bring our customers the best products with equally matched service. Since 2009, we have learned that no two farming operations are the same. Our goal is not only to bring the best technology to each grower but also to learn and teach a full spectrum approach from when each seed is planted to harvest. Though we cannot control every limiting factor, we believe we can achieve the best ROI for each grower through the correct tillage, planter, applicator, sprayer, and combine pass; Also, by managing soil health/biology, choosing the correct hybrids, feeding crops efficiently, and more. Feel free to call any of us, and we would love to learn more about you and your farming operation!
