Spring barley split root systems for evaluating rhizosphere soil carbon and nitrogen cycling under different fertilisers
MetadataShow full item record
The use of nitrogen (N) fertilisers in agricultural systems can lead to increased greenhouse gas (GHG) emissions, N runoff and leaching from soils. This research used a novel split root design to study plant-soil-rhizosphere interactions in high vs. low N input systems. To test whether the soil rhizosphere facilitated N utilisation by spring barley (Hordeum vulgare), differences in carbon (C) and N cycling between split root barley systems receiving inorganic and organic fertiliser treatments on one side of the split root system (no fertiliser on the other side) were investigated. Emissions of nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) from the soils were determined for both sides of the split root systems alongside plant productivity indicators and soil nutrient contents.
