During grazing, dung and liquid manure fertilize directly. Regular distribution of cowpats prevents rank spots. In contrast, manure from stabling must be stored temporarily with as little loss as possible until it is applied. The best method for preserving the fertilizing power of stable manure, including liquid manure, is that with straw bedding; the most questionable, yet certainly the most rational, is that of liquid manure or slurry. In slurry (liquid manure + dung), under the extensive exclusion of air, anaerobic fermentation processes take place, during which the organic nitrogen compounds mineralize into ammonia, which escapes as a gas into the air, especially during application (odor nuisance). This effect can be mitigated by an agitator. Slurry acts on the enlivening
