Not sure how a dairy farmer can compost most of his cow manure, sell the compost then use mostly commercial fertilizer for his cropland and be selected as "wisconsin sustainable dairy farm of the year". Seems pretty sketchy to me.
You can download this document for free. It is a good resource on composting manure solids. learningstore.extension.wisc.edu/products/composting-animalmanure
This is only the first basis of building soils, next process is spreading onto ground then using worms and micyllium then micoryzal fungi to begin the next processes of soil health with continual introduction of ground cover grasses and weeds and insects, that's how healthy strong disease free soils are built to sustain healthy harvesting....NOT USING PETROCHEMICAL FERTILIZERS which destroy biomes👎
