Well, there are a lot of differences in livestock fertilizer, depending on how we're applying that, when we're applying it, and what sorts of quantities we are talking about. Is it from grass-fed pasture beef, or are we talking about a feedlot system?
In the area around here, a lot of animal production is happening in feedlots, and the issue there is that there's more manure than we know what to do with. It's a great fertilizer, but we have more of it than we have land available to spread it on. It does reduce the amount of purchased fertilizer, but it can be problematic, especially if we're spreading in early spring or late winter, which can be quite damaging.
