stage of maturity of roughage
stage of maturity of roughage:
- digestibility of DM dec as plant matures, esp grasses:
1. inc cell wall contents: cellulose, lignin
2. dec cell contents: CP
- best at flowering stage
soil fertility and roughage
soil fertility and roughage:
- determines productivity and quality of pastures
