Theory 31/Grassland & Savanna/Soil carbon
Grassland Carbon Is Root Against Fire
The claim
Grassland soil carbon is set by the ratio of root turnover to fire loss, so frequent burning can offset a productive system.
01Mechanism
Carbon enters through roots and leaves through fire and respiration; the ratio determines the net balance.
02Prediction
Soil carbon should track the ratio.
03Refutation
Soil carbon tracking productivity would remove fire.
