Emissions of nitrous oxide from Irish arable soils: effects of tillage and reduced N input

Nitrous Oxide Emissions from Claypan Soils Due to Nitrogen Fertilizer Source and Tillage/fertilizer Placement Practices

Nitrogen, tillage, and crop rotation effects on nitrous oxide emissions from irrigated cropping systems.

We evaluated the effects of irrigated crop management practices on nitrous oxide (N(2)O) emissions from soil. Emissions were monitored from several irrigated cropping systems receiving N fertilizer rates ranging from 0 to 246 kg N ha(-1) during the 2005 and 2006 growing seasons. Cropping systems included conventional-till (CT) continuous corn (Zea mays L.), no-till (NT) continuous corn, NT corn...

Profile analysis and modeling of reduced tillage effects on soil nitrous oxide flux.

The impact of no-till (NT) and other reduced tillage (RT) practices on soil to atmosphere fluxes of nitrous oxide (N(2)O) are difficult to predict, and there is limited information regarding strategies for minimizing fluxes from RT systems. We measured vertical distributions of key microbial, chemical, and physical properties in soils from a long-term tillage experiment and used these data as i...
