Short-term soil drying-rewetting effects on respiration rate and microbial biomass carbon and phosphorus in a 60-year paddy soil.

Paddy soils represent the largest anthropogenic wetlands on earth. Soil drying and rewetting that occurs annually inflict significant stress on soil microbial activities in paddy soils. An incubation experiment of 60 years of paddy soil was conducted to simulate the conditions of paddy fields (25 °C and 75% air humidity) during a 16-day incubation time.
