Short summary
This is one of SLU´s agricultural long-term experiments within the subject area Water Management.
Drainage of peat soils increase soil aeration and the oxidation of the organic material gives rise to both carbon dioxide and nitrous oxide emissions. The focus of the trials at Field lab Broddbo on organic soil (fen peat) is to find measures that limit greenhouse gas emissions while maintaining or increasing biomass production.
At the site there are four long-term trials with start years 1986-2017 as well as short-term field trials financed with external funds. The oldest experiment is the Örke subsidence trial which started in 1986 and the others are, one experiment with different grasses combined with compaction, one with the addition of sand and one liming experiment.
In all field trials is biomass production measured with two silage harvests per year. In addition, climate data, soil water content, soil temperature and groundwater levels are measured. Other factors such as greenhouse gas emissions and trafficability are measured if external projects provide funding.
