Fire does have the potential to harden the ground. If you take crop land that continually has the stubble or stalks burned, this ground is very likely to be harder than crop land where burning is never or rarely done. When you burn the organic matter in the soil, you are burning up material that helps to provide aeration in the soil. Reducing the aeration can also reduce how quickly soil can absorb moisture. More runoff means more potential for runoff and erosion. Burning can also have a negative affect on earthworms which are vital to a healthy soil. You would think that no-till farming would have ground that is harder than farming where the ground is tilled, but just the opposite is true. Overtime, no-till farming will have soil that is softer.
