I know, confusing isn't it? What is happening when you "plow down" plant debris actually works out to be about a break even deal between O.M. depletion and creation. O.M. increases are achieved by limiting tillage and letting the plant growth and the work of the soil microbes actually "create" O.M..

Soil science is very complicated, but suffice to say that meaningful increases of soil O.M. are difficult to obtain in the short term, and are relatively small in the long term, mostly in the 1% to 2% range over a decade or more.
