Crested wheatgrass is higher in protein and phosphorus" content than the average for shortgrass dominants (Table 6) in all but the cured stage. The percentage of crude fibre, nitrogen-free extract and total ash is much the same as in the grasses of Table 6, while the content of ether extract is slightly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Clarke, S.
