Abstract/Contents:"Utilization of high C:N ratio farm residues is difficult because of its low value and bulk. Composting is an ideal method for upgrading the residue, however, it was not thought possible without co-composting to lower the C to N ratio to 30 to 1 or lower. We have successfully composted grass straw with a C:N of 50 to 1 using existing farm machinery and normal precipitation (115cm y⁻1 and occurs primarily between October and June). After turning and densification in the field, composting conditions were achieved with the rapid growth of thermophilic microorganisms. During laboratory incubations of the grass straw, bacteria ranged from 10⁸ - 10^D]
