How Moisture Affects the Way Soil Microbes Breathe Study models soil-pore features that hold or release carbon. Moisture conditions in soil affect the respiration rate of heterotrophic microbes. Soils are made of sand, silt, clays, and organic matter. Within all this material, miniature “porospheres” interlock to create microbial habitats made of water and gases. Modeling … Continue reading How Moisture Affects the Way Soil Microbes Breathe
