We used to figure on working cattle manure in fairly quick to keep N loss down. You could sure tell the difference in the crops for a few years between the fields closer to the barn than those a few miles away. Heaped up spreader wasn't all that welcome on some of the public roads, 14 mph tractor speed made the further fields more trouble than they were worth. This was much fresher than what's in your pictures.
