You get to know your own ground pretty well after you farm it for years, so the soil test is a back-up and a confirmation for your own feelings in many cases. I’ve been soil testing every 2 to 3 years and more often than that if there’s an issue.
I just had some samples taken last fall, and I watched them take the samples. They don’t use GPS, but they know the farm and they won’t mix in samples from a sandy spot or from an old building site.
I’ve worked with the same retailer for 40 years, a family-owned elevator. They spread the fertilizer, too, and know the farm like I do. I’m confident we’re not over-applying based on soil tests and removal rates.
I’ve learned over the years that you have to trust somebody, and I trust them. It’s really pretty simple for me.
