NE Indiana-Fort Wayne and NE China | And to just be clear, not all compaction is mechanical.....3 and 4" rain events cause most of it here. I do believe notill its still the best practice, but I need to do a maintenance chisel every once and a while as I do not have adequate drainage. Deep ripping did not show a better return "here".
Wayne, the element missing in your logic is called "micro-erosion". It's a term coined by a German soil scientist in the late 1930's. He used a microscope to observe a discrete concentration of silt soil particles. This zone of silt had occluded the macropores where air and water pass each other as water moves downward in the soil profile. Read all about it at www.solcursebuster.com. Your periodic use of the chisel is addressing this very universal problem. Unfortunately the chisel and resulting tillage required set you back to square one in your effort to improve soil health metrics. |
