  1. 1. Växthusgasutsläpp vid sandinblandning i torvjordar

    University essay from SLU/Dept. of Soil and Environment

    Author : Andreas Mattsson; [2018]
    Keywords : torv; sand; gjuterisand; koldioxid; växthusgasutsläpp;

    Abstract : Peat soils are organic soils which make up significant parts of Sweden land area. Peat soils are commonly used in agriculture. Growing crops in these soils require drainage which speeds up the degradation of the organic matter and increases the greenhouse gas emissions. READ MORE

  3. 2. Liming and deep cultivation as long term mitigation actions to lower the rate of peat decomposition and CO2 emissions from peat soils

    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

  4. 3. Mineralinblandning i torv och dess påverkan på koldioxidutsläpp

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna Lindgren; [2017]
    Keywords : sand; vattenhalt; torvdjup; organogena jordar; miljöpåverkan;

    Abstract : Swedish peat soils are highly productive provided they’re drained and handled with care. However, the peat soils’ lack of buoyancy and their need for constant draining have resulted in them being viewed as less attractive by farmers. READ MORE

  5. 4. CO2 emissions from drained calcareous organic soil profiles from the Mästermyr area

    University essay from SLU/Dept. of Soil and Environment

    Author : Erik Siggelin; [2017]
    Keywords : peatlands; peat; marl; Gotland;

    Abstract : Peatlands in their natural state are in general considered as net sinks of greenhouse gases over time, with the accumulation of dead organic matter as peat. Drained organic soils have been of importance for Swedish agriculture for more than a century. READ MORE

  6. 5. Organogena jordar : hur man kan minska markytesänkning och växthusgasemission

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Fredrik Karlsson; [2017]
    Keywords : organogena jordar; markytesänkning; mulljord; emission;

    Abstract : Odlade organogena jordar motsvarar idag ca 7 % av den svenska jordbruksmarken. Genom dränering av tidigare våtmarker har de gått från att ackumulera kol till att släppa ut kol i form av koldioxid. READ MORE
