Study Site Trials

The SICS selected for trialling in this Study Site are described below:

General Treatment
 Study Site Trials
Crop rotations, tillage, fertilization

1. CROPSYS crop rotations, organic and conventional/row cropping with catch crops -Rotation (O2,O4,C4),O2 organic (S. barley: ley, Grass‑clover, spring wheat, spring oats), O4 organic (S. barley, Faba bean, Spring wheat, Spring oats), C4 conventional (S. barley, Faba bean, Spring wheat, Spring oats). +/- catch crop, +/- manure

2. CENTS / soil tillage intensities and cover crops (maybe) - Ploughed/ harrowed/direct drilled, crop type, catch crop type, +/- straw

3. Screening different types of catch crops (maybe) - Different species of cover crops. This year also including mixtures of different species

4. Askov and Samsø / as demonstrated during the 2018 annual meeting excursion (demonstration)

5. Askov and Jyndevad / experiments with different levels of fertilization and liming (LT)

Geographical description

The Danish site is centered in the Municipality of Viborg, and the Region of Central Denmark where the main Agricultural Research Centre and the Aarhus University, Department of Agroecology is also situated. The sites draws on extensive long-term data from the field stations (see below), and nearby agricultural landscape study sites, from where data collection has been coordinated in the NitroEurope EU integrated project (2007-2011), the MEA_scope EU strategic research project (2004-2007) etc. and and series of other research projects (1994-present).

The Danish site represents the most agriculture and livestock intensive western parts of Denmark, with extensive data available for upscaling and generalization. The area is dominated by loamy moraines (about 40-70 m above sea level), with agriculture and rotation cropping systems as the dominating land use. The climate is temporal coastal with significant surplus rainfall, especially outside the main growth season. Moreover, for the studies we will include our very near collaboration with the Danish Farmers extension services ( and the strong local farmers associations.

Pedo-climatic zone
Dominated by sandy-loamy soils, with some peat soils. Situated on the border between the atlantic and the continental biogeographical region, Atlantic North climate. Some sandy soils are irrigated, and we have data on both irrigated and non-irrigated conditions.
