This seems like an absurdly energy-intensive plan because you'd have to spend energy to maintain your mountain-sized pile .. which will heat itself up if it ever reaches warm enough to start decaying.
The most viable farm based approach would be "reverse coal mine": make charcoal from the biomass by reduced-oxygen combustion, then put it all in the big pit you made when you dug up all that coal.
However, there's no economic model for any of this, so carbon capture is never going to go beyond pilot schemes.
