At commercial scale, I think what is done on more modern farms is cover cropping after a cash crop is harvested, with a winter that kills the cover crop before seeds develop. Before is dies and becomes a thin compost residue layer, the cover crop is photosynthesising and converting carbon dioxide into carbon and other nutrients which exude through the roots into the soils, keeping the microbiology alive for the spring crop. That live soil is going to be as good as compost, and it doesn't need to be disturbed like compost normally is.
