Standing dead and litter decomposition of big bluestem foliage and flowering stems were measured for two years using litterbag methods. Mass, nitrogen and phosphorus content were measured.
To measure mass, N and P flux of standing dead and litter.
Location of Sampling Stations: 004B, 000B, Florence and Tully soils (1981-1983)
Frequency of Sampling: Stratified by watershed and soil type. 400 bags placed in field at beginning. 5-10 harvested quarterly for first year and every 6 months during the second year.
Variable Measured: Date, location, length of time in field, initial and final weight, matter type.
Methods: Air dry wts - (foliage and stems, separately) recorded prior to placement in field, reweighed after harvest. Tissues ground, Kjeldahl digest and sent to soils testing lab for N and P analysis.
Preliminary Calculations: Initial dry mass and N and P content calculated from subsample harvested immediately after placement in fields.
