I have seen chicken waste used as well as dairy cow waste, collected when the animals are in a confined interior space. <BR/><BR/>With management-intensive rotational grazing techniques, the manure is naturally left on the pastures as the herds pass over them, and the density of application is typically much lower. It would be great to see a study of these sustainable agriculture techniques re: emissions. I'd imagine the gas released is much lower than either of the other two options.<BR/><BR/>Take care,<BR/><BR/>SaraAnonymousnoreply@blogger.com
