The generation of acidity from oxidation of pyrite in acid sulfate soils requires the transport of oxygen into the soil profile. The sink for this oxygen will not only be the chemical reaction with pyrite but the biological processes associated with both microbial and plant respiration. The biological sinks in burning the oxygen ([O.sub.2]) will release C[O.sub.2]. The respiratory quotient which is the molar volume ratio of [O.sub.2] : C[O.sub.2] varies between 1.3 and 0.7 depending on the ...
