Organic Soil Amenders was incorporated in 2008 with the intention of providing farmers and ranchers with one of the most important amendments for modern soil and crops- calcium. With the understanding that healthy soil produces healthy crops, and healthy crops feed livestock and families, gypsum was that perfect amendment choice to apply just about everywhere. It was also important to provide an affordable and easily distributed source. From this humble beginning, OSA has grown to provide more products and services, and has increased our ability to serve those in the production of our region’s healthy food and forage.

Dave and Jean combine their backgrounds in ranching, farming, forest and plant biology, chemistry, landscape services, and professional operation of heavy equipment- offering a well-rounded wealth of knowledge to introduce our products to your program.

We look forward to serving you!

"We have OSA apply gypsum annually in the fall which helps with our heavy soil."
