Abstract
Methods
Biomass measurements made once, on average 28 days apart, in each of consecutive months April, May, and June in 2000, 2001, and 2002 in three 4 x 4 m fenced plots at each of seven sites from the Long-Term Grazing Exclosure (LTGE) experiment. Four 25 x 25 cm quadrats were clipped to the ground surface in each 4 x 4 m plot, with green material sorted to stem versus leaf and green separated from litter (gray plant material) Different quadrats were clipped from different locations within plots in each month. Green material was air-dried at 45oC for a week and then weighed. Sites varied in mean annual rainfall from 490 – 890 mm/yr , soil N from 0.05% to 0.22% and soil P from 0.005% to 0.15%
