I am thinking, during the winter, I would like to make compost, from manure only. Like the stuff they sell in bags. Manure of course is only 'green' and should be mixed with a 'brown' on a 25:1 ratio, however, the 'brown' is likely to cost money and take longer. Does anyone know the technique for manure only composting or the best source to discover the technique? Thanks for any and all ideas.
