Is Soil Fertility Decreasing? Are agricultural soils less nutritious today than they were 50 years ago? I think most people believe these statements to be true. The idea has certainly been promoted a lot in the last 20 years. Our food is less nutritious than it used to be and the main reason is that soils are being depleted of nutrients.
There is also a big movement to remineralize our poor soils. Hopefully, adding things like rock dust will bring it back to historical levels. The organic movement is also very big on solving these kinds of soil issues. Before we can understand the benefits of such actions it is important to determine how big of a problem we really have. How depleted are our soils? Which nutrients are actually missing?
