There is a *reason* for manure management plans, especially when you consider that MOST for-profit farms (the largest segment of farm animal-owning people) use prophylactic antibiotics, have huge numbers of animals with massive amounts of waste, and have major issues with disease due to over-crowding. In addition, fertilizer and farm waste run-off is a huge environmental concern for our water systems.
Now, that said, one of the major issues facing small farmers, and growing the number of small farmers, is that they're expected to adhere to the exact same regulations as Big Ag. First, the challenges and issues they face are different from Big Ag not only in scale, but in scope and execution as well. Second, where hiring one person to just do the paperwork is completely reasonable for a several hundred thousand to several million dollar a year organization, for the small farmer who is accountant, legal consultant, vet, farmer, hired hand, and marketing specialist all rolled into one the paperwork burden is vastly different.
If/when we increase the number of animals on our farm we'll have to create a manure management plan, and I found that out when I was doing my research on the local laws and regulations. Knowing that, IMHO, is part of the responsibilities of an owner, just like knowing your local leash laws for your dog.
