As the title says, I recently added a link to a web version of the manurwkst.xls manure value spreadsheet that has been used in educational workshops around the state.
Also, at the request of the leadership of the Minnesota Custom Applicators Association, I developed a spreadsheet for estimating costs and returns for a custom manure application business. Since the spreadsheet is fairly complex, I have added two short youtube videos explaining how to fill it out.
