Valid Range: 0.0 to 1.0
GRZEFF - Effect of grazing on production:
0 = grazing has no direct effect on production
1 = linear impact on aboveground production
2 = quadratic impact on aboveground production and root/shoot ratio
3 = quadratic impact on root/shoot ratio
4 = linear impact on root/shoot ratio
5 = quadratic impact on aboveground production and linear impact on root/shoot ratio
6 = linear impact on aboveground production and root/shoot ratio
Valid Values: 0, 1, 2, 3, 4, 5, or 6
