Other claims from this paper (13)
- Observation Unburned prairie produced 4.351 X 10 6 cal/m 2 of net productivity in 1962, representing 992 g biomass.
- Observation Roots supplied slightly over half the annual increment.
- Observation Total growth in 1963 was 1,133 g/m 2.
- Observation Maximum energy budget equalled 2.6 turnovers.
- Intervention effect Fire approximately doubled aboveground yield in years with favorable rainfall.
- Intervention effect Drought sharply curtailed productivity gains from burning relative to controls.
- Observation End-of-season aboveground biomass was approximately twice the standing crop.
- Observation Aboveground material lost 57% to 65% dry weight during April to September.
- Observation Aboveground material lost 31—39% dry weight over the remainder of the year.
- Observation Aboveground biomass turnover was estimated at 2 years.
- Observation Root biomass turnover was estimated at 4 years.
- Observation Caloric content of successive turnover increments decreased with age on a dry-weight basis.
- Observation Four-year-old litter showed some increase in caloric content on an ash-free basis.
