Results from the first year - six new bioreactors using wood chips

There is a huge need for new measures to help reduce nitrogen leaching to the aquatic environment. Recent results from Aarhus University demonstrate that between 29 and 49 percent of the nitrogen are removed when drainage water is led through a bioreactor with wood chips. However, this is to be confirmed in more experiments.

Computer model can determine nitrogen mineralisation of catch crops

Reduced nitrate leaching and improved plant nitrogen availability are among the benefits of catch crops. A new model built by researchers from Department of Agroecology can determine the mineralisation of catch crops, and when linked to an agroecosystems model, it allows improved estimated of nitrate leaching and nitrogen supply to following…

Biochar as a source of phosphorus for crop fertilisation

Pyrolysis is not only a source of sustainable and climate-friendly energy, but the residual product from pyrolysis, biochar, can, in addition to carbon binding, also act as phosphorus fertiliser on agricultural fields.

Intensive and specialized farming may provide higher yields, but agroecological farming deliver other benefits.  Illustration: Yen Strandqvist/Chalmers University of Technology.

Comparisons between organic and conventional agriculture need to be better, say researchers

The environmental impact of agriculture and food production is a highly topical issue and frequently discussed worldwide. However, researchers from Aarhus University, Chalmers University of Technology and INRAE point out that the comparison method most widely applied (LCA) often lacks some rather crucial factors. Often, the LCA method does not…

European Research Alliance works for agriculture of the future without chemical pesticides

Twenty-four European research organisations from 16 European countries have joined forces in a new research alliance to forge the foundation for reducing dependence on chemical pesticides in EU agriculture. The initiative is called 'Towards a Chemical Pesticide-free Agriculture', and the collaboration will rethink the way in which research is…

New model can predict if the soil is too wet or dry for tillage

Researchers from the Department of Agroecology at Aarhus University, among others, have created a model that will help farmers in the future predict whether their fields are too wet, dry or suitable for tillage.

Researchers compile and review literature on plant chemical impacts on nematodes

Certain nematodes can cause great damage to crops and yields, and they can be difficult to control. Researchers from the Department of Agroecology at Aarhus University have compiled and reviewed the literature to gain a better understanding of the nematodes and find more effective control possibilities.

Carbon is still active after 20 years in the soil

A 20-year-old experiment on Askov research station at Aarhus University has helped researchers from Aarhus University, among others, find out what happens to organic carbon, left in the soil for many years, and which organisms decompose it. The experiment shows that carbon, which has been fixed in the soil for many years, is still active and a…

Bio-based products of the future and sustainable alternatives

Agriculture in Europe is under pressure to meet environmental requirements, maintain high production and meet demands for a sustainable food supply. The use of fossil fuels and products, as well as imports of soy protein, have serious environmental and climatic consequences for vulnerable areas of the world. At a seminar and exhibition on 28 April…
