In laboratory experiments, water availability was the major factor controlling microbial respiration and activity as soils dried. Both respiration and activity declined continuously as gravimetric water content decreased. Microbial respiration and activity increased sharply within 30 min of rewetting gradually dried soils. These increases appeared to be largely due to the C released from microorganisms, killed by drying, being metabolized by the surviving microorganisms.
