Field day for work partners

The annual field day in AU Flakkebjerg gave the Department of Agroecology's collaborative partners the opportunity to see for themselves if the various pesticides work as well as they should.

It is one thing to study facts and figures, but to see and feel the results hands-on often provides an even better picture. The annual field day in selected research plots at AU Flakkebjerg on June 20, 2017 gave business partners and others of the Department of Agroecology's collaborative partners the chance for both. Here, they could see for themselves how effective the various pesticides have been under various conditions, and they could study and discuss facts and figures regarding pesticide dosage, crop yield, and occurrence of fungi or weeds.  

Approximately 40 people from agrochemical and agrifeed companies, advisory services and the authorities normally participate in this full-day field event. This year was no exception. The participants used the day to have a closer look at the research trials and to catch up with colleagues and strengthen their networks. 

Senior Researcher Lise Nistrup Jørgensen led the way during the sunny but windy day in the field, but several other researchers, including visiting PhD students from Germany, also gave short explanations of their results. Most of the results are preliminary but give interesting indications nevertheless and have in some cases led to adjustments in the field trials. 

In the fine, dry weather the guests strolled around among the research plots that clearly showed how wide a range of crops that the Department of Agroecology deals with, including barley, wheat, seed grass, cabbage, onions, beetroot, strawberries and Christmas trees.  

Senior Researcher Lise Nistrup Jørgensen related her experience from one of the trials with fungicides in barley:

The visitors at the field day studied the research plots with cereals very closely to view the occurrence of fungal diseases in the plots with various treatments:

Associate Professor René Gislum told about various aspects of the groundbreaking project Future Cropping, in which AGRO has the lead on several of the work packages. Among other things, the Department of Agroecology is working on developing new technology for more efficient nitrogen fertilisation. René Gislum also touched on the pros and cons of drones and satellites for use in research and commercial farming, respectively:

Principal Investigator Peter Hartvig told about the experience with controlling weeds with the aid of reduced tillage in vegetables, including cabbage, onions and beetroot. Combining direct sowing of the crop in a catch crop that is wilted in the spring with strip tillage has given good results:

Peter Hartvig also explained that a combination of white clover and strongly reduced dosages of glyphosate might contribute to keeping weeds in Christmas trees at bay. There are, however, still some practical problems that need to be solved. So far, it appears that the clover can take over if it is established the year before the Christmas trees are planted. The trial has therefore been adjusted so that the trees and the clover are planted more or less at the same time:

Some of the researchers in AU Flakkebjerg grow weeds on purpose. This is done with the aim of testing various herbicides on a specific weed. Senior Researcher Solvejg Kopp Mathiassen told the guests about her experience with testing various herbicides to control thistles. The thistles have been gathered from various crop rotations and they are being tested to determine if they react differently to herbicide treatments:
