Dr. Ray Weil has spent his whole life looking at and learning about soils and how they work to keep us all fed. In fact, he literally wrote the book on soils.
He has a message for farmers and ranchers concerned about how their soils affect forage growth and profitability: Think deeper. Think about more than the top 12 inches. There’s a lot going on down there, and in fact that could be where a lot of the moisture your forage needs is. In this first 3:48 minute video he takes you on a tour of a soil pit to show you what’s going on further down than we normally look.
Sometimes that moisture is trapped below a “plow pan” or a layer of compacted soil. But you don’t need a bigger tractor with a bigger plow to break that up. In this second video Ray says, “Let nature do it for you” with the simple addition of cover crops. Check it out!
If you want to go into “depth” on the nature and properties of soils, Ray’s book is the one for you. It is the hallmark text on the topic and provides an integrated understanding of the diversity of soils, the soil system and it’s role in the ecology of the planet.

We have a thick layer of caliche at our place and are looking for a way to get through it, break it up, etc. I saw in another post that you don’t see a benefit in using a keyline plow for most operations, and honestly if I can get away without spending that money I’m happy. What would you suggest for dealing with caliche?
