    Abstract : Popular Abstract in Swedish Studierna som presenteras i papper I till IV i min avhandling visar markvattnets betydelse för marklösningens kemi och växternas respons på förändringen i vattenhalt. Med mina experiment har jag studerat dels kalkjord med olika vattenhalter och dels markvattens påverkan på växternas näringsupptagning i växthus. READ MORE

  2. 2. Nitrous oxide emission from soil : On extrapolation from soil environmental factors

    University dissertation from Linköping : Linköpings universitet

    Author : Kerstin Robertson; Linköpings universitet.; Linköpings universitet.; [1995]

    Abstract : Nitrous oxide(N20) is a natural component of the atmosphere which contributes both to the greenhouse effect and to the destruction of stratospheric ozone. National as well as global inventories indicate thatboth natural and anthropogenic emissions from terrestrial ecosystems constitute a large fraction of the annual loading of N20 on the atmosphere.

    Abstract : Popular Abstract in Swedish Populärvetenskaplig sammanfattning: När udda blir mainstream - om stress och likriktning i växtsamhället I skogen råder stress på många sätt, och precis som i det mänskliga samhället har stressen i växtsamhället ökat under de senaste decennierna. Dessa händelser har heller inte skett oberoende av varandra. READ MORE

  5. 5. Feasibility study of soil washing to remediate mercury contaminated soil

    University dissertation from Luleå : Luleå tekniska universitet

    Abstract : Mercury (Hg) cannot be degraded. Therefore only two principal processes are available for the treatment of Hg-contaminated soil: (1) the separation of Hg from the soil or (2) the stabilisation of Hg within the soil. Prior to selecting a suitable treatment technique, it is necessary to have an understanding of Hg behaviour in contaminated soil, i.e. READ MORE
