| tkoppel - 1/16/2019 16:29 Matt, I think you make some very valid points, but I hope you realize as you say "moving the needle on getting SOM closer to what it was in it's native, pre-cropland conditions" doesnt apply equally to all soils. The prairie soils you're probably most familiar with in many cases bear few resemblances to the podzols prevalent in the upper and lower great lakes and the north east. Our native soils, regardless of how well managed they have been, have never had the SOM prevalent in your soils, even in their run down state. Guess my question is weather you can improve our soils to a point equal to or better than they were when this kind of land was first cleared? Forested soils don't have as much OM as prairie soils do, partly because so much organic material is sequestered in the timber. Yes, I think SOM can be improved in those soils beyond what it was in its native state. |
Another why tillage has little to do with building OM
