Abstract
Intensive agricultural practices strongly increase CO2 emission from soil. Synthetic metal-porphyrins were shown to significantly decreased CO2 emission from soil due to an in-situ catalysis of oxidative polymerization of soil organic matter. The effects of iron-porphyrin (POR) amendments on soil microbial communities were evaluated in bulk-soil and rhizo-soil during 4 years. POR treatment influencing in different way aerobic free-living N2-fixing, ammonia-oxidizing and denitrifying bacterial populations as well as OM degrading microbial population in bulk- and rhizo-soil. Fungi population showed higher sensitivityto POR or to POR end-products.| File | Dimensione | Formato | |
