Its a location thing.  Im guessing your ground is over 1.5% organic matter.   Ive heard some ground in michigan is so high it can catch on fire in a drought (peat).  The climate and rainfall amounts combined with low drainage slows the mineralization of the soil.   In arid climates the opposite is true and the plow accelerates soil OM decline and water holding capacity which is a very bad thing in those climates.   Disclamer: I have 6 plows but notill everything "here".



This. The only thing wrong with molboard plowing in my neighborhood is the time it takes and the dead furrows it leaves in the fields.

I understand warm winter climates and thin topsoils it is different.

My farm averages 4% organic matter with over a century of plowing. The microbes don’t like working until you get the soil drained out some from the typical late frost and snowmelt flooding. Might only be 4 months a year the soil is really well above 50 degrees.

I have moved on to a chisel plow a few years ago, but the molboard is sitting there waiting….
