Soil properties, crop production and greenhouse gas emissions from organic and inorganic fertilizer-based arable cropping systems

▶ Increased carbon input enhanced microbial activity and N transformation processes. ▶ Manuring and catch crop incorporation prior to sowing increased grain yields in organic systems were similar to those achieved in the system where inorganic fertilizer was applied. ▶ Organic systems had higher cumulative heterotrophic CO2 respiration than inorganic fertilizer-based systems.
