Finally, autumn has also come to SITES Lönnstorp with several nights below zero. The focus in the near future will be to harvest sugar beets and also to start the second year's measurements of nitrous oxide in the Residuegas project. This project uses the SAFE (SITES Agroecological Field Experiment) infrastructure and investigate how different crop residue management strategies affect nitrous oxide emissions. Read more here!

This year, SITES Lönnstorp took over the management of two long-term experiments in northwestern Scania that investigate the possibility of using various integrated weed control strategies to reduce Black grass (a problematic weed) in crop rotations dominated by winter cereals. The experiments were started in 2012 and 2015 respectively and compares five different weed control strategies that include different combinations of plowing, herbicides, direct sowing and reduced tillage. Preliminary results indicate that strategies that include direct seeding reduce the seed bank and the incidence of Black grass. However, the experiment needs to be continued during a number of years in order to confirm these preliminary results. Read more here!

The Formas project "Phosphorus efficient agriculture with arbuscular mycorrhizal fungi" is a new project from Lund University that also uses the SAFE infrastructure at SITES Lönnstorp. The project will, among other things, investigate whether perennial crops (e.g. the wheatgrass Kernza) take up more phosphorus with its larger root systems than its annual counterparts (e.g. winter wheat) and whether these larger root systems also can maintain a higher mycorrhizal biomass. Equipment to study this was placed in SAFE in mid-October 2019 and will be assessed after harvest 2020. Read more here!
