Who we are and what we do.
Midwestern BioAg is a program, not a quick-fix. We fertilize most every crop known to man – from alfalfa to zucchini. So whatever you farm and whatever size your operation, we can help you be more productive.
Our knowledge is based on decades of experience. Tillage, no-till, organic – it doesn’t matter. We work with it all so you can be more profitable.
What drives us.
We’re a company driven by ethics. While we’re dedicated to helping farmers and ranchers become more productive and profitable, we’re equally dedicated to an agriculture that is safer, healthier, and more sustainable for future generations.
We believe that the principles of biological farming provide the basis for a revitalization of agriculture and rural communities. Working with nature gives abundant yields, superior quality crops and livestock, and, equally important, a better quality of life.
The name BioAg stands for Biological Agriculture. It’s a dramatic contrast to ‘conventional’ or ‘assembly line’ agriculture. Bio stands for life, and logical represents common sense. Therefore, biological farming is working with the life in the soil, with plants, and animals – using a common sense approach that embraces, rather than attempts to dominate, nature. We do everything we can to promote life. And, while quantities of commodities produced on your farm remain important, we place equal importance on quality. Knowledgeable consumers are demanding natural, unadulterated foods, and our goal is to help you profitably tap into that ever-growing market.
We truly believe in our mission statement: We’re here because we have a passion for farming, a desire to change agriculture for the better, and the belief that farming should be profitable and fun.
