Carbon bedding bonds to nutrients and ammonia in animal wastes preventing pollution of the air or ground. When animals overwinter on bedding, they pack their manure down tight removing air pockets leading to anaerobic decomposition which provides free heat contributing to the animals’ health and comfort. Letting the pack decompose for 6 months lets the microbes digest some of the material as well as begin to mineralize the nutrients making them bioavailable to plants.
The concept is old and the cornerstone of fertility and soil building on my farm. There is one small problem: I don’t have animals yet!
But my uncle has beef cattle and pigs and was willing to part with some manure so I could start applying it to my pasture.
I wanted to add a bit more carbon to the pack so I lined my truck bed with sawdust before heading to my uncles farm. Upon returning I added ancient hay to the top of the pile and it all mixed together as I unloaded it by hand.
Once I got back to my farm with a truck overloaded with manure, I tossed the first bit into the compost bin to bolster the nitrogen content to rev the compost pile up one last time before the fall temperatures cool it down. On top of the compost I added a bit more sawdust.
The rest went quicker than I had anticipated. I used it to fill in divots and cover rocks that have appeared on the vehicle track through the pasture. There are a few more places along that track I would like to build soil, most notably around exposed rocks. Any future loads will be spread on the pasture around rocks that are barely exposed. When it breaks down a bit more, I can pull back the hay mulch and plant some clover and buckwheats seeds before returning the mulch.
