My philosophy is that whatever you do on your farm should improve soil health. But how do you know what that is? The USDA defines soil health as, “The continued capacity of soil to function as a vital living ecosystem that sustains plants, animals and humans.” I would add to that definition and say that soil health isn’t just the capacity to function, it’s the capacity of soils to function without intervention.
What counts as “intervention?” Does intervention mean biotechnology, insecticides, fungicides and tillage? Is fertilizer an intervention? Do these interventions make your farm better for future years? I believe money spent on interventions needs to be shifted to inputs that yield soil health.
Appropriate intervention when absolutely needed is wise, but the goal is minimum intervention — in other words do everything you can to get the soils healthy and mineralized. Mineralize your soils using exchangeable nutrient sources that come from the carbon biological system. You have to create an ideal home for soil life and feed them in order to build soil health.
Remove the negatives, which include monoculture crops and excessive tillage. Reduce the use of other possible negatives added through harsh soluble fertilizers and excessive nitrogen, not to mention chemicals and biotechnology.
Farming for soil health means treating your farm like a system. For years we have been promoting the “rules” of biological farming (Six Principles of Biological Farming). Following these rules will lead to healthy soils that produce good yields. The soil health guidelines you now see published in many places focus on minimum disturbance with an emphasis on no-till. In my opinion not all soils are capable of being farmed no-till. Continue Reading →
