Modelling tillage and nitrogen fertilization effects on soil organic carbon
1 Agricultural management plays an important role in global warming mitigation due to 2 its effects on soil organic carbon (SOC) dynamics. In Mediterranean agroecosystems, 3 the interactive effects of tillage and N fertilization on SOC storage have scarcely been 4 studied. Hence, we here present a modelling study in which the effects of both tillage 5 and N fertilization on SOC dynamics are inv...
متن کاملThe myth of nitrogen fertilization for soil carbon sequestration.
Intensive use of N fertilizers in modern agriculture is motivated by the economic value of high grain yields and is generally perceived to sequester soil organic C by increasing the input of crop residues. This perception is at odds with a century of soil organic C data reported herein for the Morrow Plots, the world's oldest experimental site under continuous corn (Zea mays L.). After 40 to 50...

متن کاملSimulating long-term and residual effects of nitrogen fertilization on corn yields, soil carbon sequestration, and soil nitrogen dynamics.
Soil carbon sequestration (SCS) has the potential to attenuate increasing atmospheric CO2 and mitigate greenhouse warming. Understanding of this potential can be assisted by the use of simulation models. We evaluated the ability of the EPIC model to simulate corn (Zea mays L.) yields and soil organic carbon (SOC) at Arlington, WI, during 1958-1991. Corn was grown continuously on a Typic Argiudo...
متن کاملMycorrhizal responses to nitrogen fertilization in boreal ecosystems: potential consequences for soil carbon storage
Mycorrhizal fungi can contribute to soil carbon sequestration by immobilizing carbon in living fungal tissues and by producing recalcitrant compounds that remain in the soil following fungal senescence. We hypothesized that nitrogen (N) fertilization would decrease these carbon stocks, because plants should reduce investment of carbon in mycorrhizal fungi when N availability is high. We measure...
