I presented preliminary results from a study in which we investigated the economics of alternative manure managements practices (on size economies and other size and scale implications) for dairy farms. We quantified the estimated methane emissions and documented estimated costs of alternative technologies currently used (or that may be used) to manage manure. We evaluated the economic effects of the adoption of these strategies on different sizes of commercial dairies, and project the economic impacts of these new regulations, focusing on small dairies in California.
