Liming on acidic soils reduces nitrous oxide emissions and increases yields

Researchers from Aarhus University and the Norwegian University of Life Sciences have found that when farmers apply lime to acidic fields, they can not only increase crop production, but also reduce nitrous oxide emissions and increase the soil capacity to oxidize methane, thereby contributing to climate change mitigation.

Researchers evaluate the competition for food plants between honey bees and other bees in Denmark

Overlap of food and the Danish list of threatened species (red list) can help to guide action plans and management of bees in nature areas in Denmark, new research from leading European bee researchers from Aarhus University, among others, shows.

Green demonstration plant ravaged by fire

A building at AU Foulum, which among other things houses a demonstration plant for biorefining, was ravaged by fire on Tuesday night. Despite damage to the building, the researchers expect that the experimental activities will be able to resume within two weeks.

Lucerne and chicory have the potential to loosen compacted subsoil

Using a medical CT scanner in a laboratory experiment, researchers have assessed the ability of five crops to loosen heavily compacted soil caused by heavy machinery. Long-term cultivation of lucerne and chicory show great potential for mitigating subsoil compaction.

PhD defence: Non-destructive techniques for mapping agricultural subsurface drainage systems

During his PhD studies, Triven Koganti investigated a variety of proximal (Ground penetrating radar, Magnetic gradiometer) and remote (Unmanned aerial vehicle imagery captured using different cameras) sensing technologies to discern their potential in mapping agricultural subsurface drainage systems (popularly known as “tile drains”). Triven…

New model predicts harvest date as well as the efficiency of cover crops

As a policy support response to the Danish Agency for Agriculture, researchers from Aarhus University have created a model that, based on air temperature, can estimate harvest dates for spring barley and winter wheat. And in an article in "Field Crops Research", the same researchers have used the model to show how the harvest date for crops can be…

EU Water Framework Directive and Danish agriculture in 1900

The work with the establishment of reference conditions in Danish coastal waters has so far been based on the distribution of eelgrass around 1900, and current measurements of nitrogen concentration in watercourses with virtually no agricultural activity, as well as estimated historical national nitrogen balances. In a new publication in the…

Webinar: How do crop residues affect greenhouse gas emissions in European agriculture?

Join us for a webinar on the ResidueGas project on 3 May 2021. You can meet researchers from most of Europe and learn more about crop residues, their impact on greenhouse gas emissions, and how they are otherwise handled sustainably in plant breeding.

Tyre evolution, traction and repeated wheeling effects on the risk of soil compaction

One of the main threats to the quality of agricultural soil in Europe and elsewhere is soil compaction. During her studies, Loraine ten Damme studied processes of soil compaction, in particular tyre-soil interactions and soil response as affected by tyre evolution, traction and repeated wheeling. Loraine investigated, among others, the effect of…
