The effects of pesticides on soil organisms are complex

Research shows that the interactions between pesticides, tillage and fertilisation are complex with respect to effects on the myriad of life forms in the soil. Such interactions should be considered in risk assessment of pesticides.

Fungi can lend a helping hand to potatoes

Life can be difficult for a potato plant when the soil is thirsting for water and nutrients – unless the plant is given a helping hand from a certain group of fungi.

Potatoes and biochar are not friends

Adding biochar to soil can reduce yield in potatoes – particularly if the soil is deficient in phosphorous and water.

New method for quantifying methane emissions from manure management

The EU Commision requires Denmark to reduce drastically emissions of greenhouse gases from agriculture. But it is currently not possible to quantify emissions of methane from livestock manure - and to document effects of changes in management. A new research article addresses this challenge and proposes a method which could be an important step…

Scientists from Aarhus University are investigating various alternative strategies for protecting crops against diseases, pests and weeds so that pesticide use can be reduced or even dropped. Photo: Colourbox

Fruit, vegetables and potted plants bursting with health

Pesticide consumption in the horticultural sector in Denmark is low compared to other countries, but there is still room for improvement with the aid of new methods that are being developed in collaboration between researchers and the horticultural industry.
