We are investing long term effects on soil properties, content of organic matter and carbon storage of crop cultivation dominated by cereals versus crop rotations with grassland and cereals in sandy soils.

We are investigating carbon storage, soil fertility, biological activity, soil structure and other soil physical properties on farms in Surnadal and Solør/Sør-Østerdal. On each place we have chosen four farms that for a long time have cultivated cereals or cereals with some potato and four farms that have crop rotations with grassland and cereals. Among these farms there are farms that are cultivated according to organic certification and conventional farms. We have chosen farms so that pairs with cereal/crop rotation do have as similar soil as possible. On each farm two fields are chosen where cereals are cultivated in 2020. Plant growth, root-development, earthworms, aggregate-stability and aggregate distribution, soil density, ignition loss and content of labile and total carbon and nitrogen will be investigated. We will organize three open days. On these days we will visit a farm with cereal dominated areal cropping and one with a grassland in the crop rotation and judge the soil properties with visual assessment of soil structure, earthworms, penetrometer and water infiltration.

Target groups are farmers, Norwegian Agricultural Extension Service, the agricultural authorities, farmers unions and students. The results will be compiled in a NORSØK report. Results from the investigations are published on Agropub and in relevant popular journals. Through the open days and web seminars we will have dialogue between agricultural advisers, farmers and researchers on the impact of the field observations and measures for improved soil physical conditions and increased carbon storage.
