Queens, sex and colony collapse

Royal sex with multiple partners, venereal diseases and the collapse of colonies – welcome to the world of bees.

Machine design and crop choice can reduce soil compaction

Heavy agricultural machinery used to cultivate the soil, apply animal manure and harvest crops contributes to the degradation of farmland. Innovation in relation to technology and crops can help remedy this serious problem.

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.

Potato yield can fall if biochar is added to the soil - especially if the soil is deficient in water and phosphorous. Photo: Colourbox

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.

Plant roots can affect the plant's local environment. This ability can perhaps be used to reduce pesticide use. Photo: Colourbox

Plants design their own environments

Plant roots can influence their local microbiological environment to a significant extent. Researchers aim to use this ability in plants to increase yield and reduce the use of pesticides in agriculture.

Potatoes should not bake in the potato field

If you are a potato plant then a sweltering summer can be too much of a good thing. New studies show a clear correlation between increasing temperature and decreasing yield.

DCA Annual Report focuses on research-based policy support

In 2015 DCA – Danish Centre for Food and Agriculture completed more than 150 policy support assignments for the Ministry of Environment and Food of Denmark. Read more about this in the recently published annual report from DCA.
