    University essay from SLU/Dept. of Soil and Environment

    Author : Joakim Hermansson; [2017]
    Keywords : peat soil; organic soil; decomposition; CO2 emission; water retention;

    Abstract : Cultivated drained peat soils have a complex relationship towards CO2 emissions and the contribution to global warming. Many people are unaware that the CO2 emissions from peat soils, also known as organic soils, vary a lot within, and between, the fields. Permanent grassland may not always be the best mitigating action for lowering CO2 emissions. READ MORE
