  1. 1. Quantifying panarchy of lake systems: implication for resilience and management (Case study)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ran Hur; [2021]
    Keywords : Sustainable Development; Liming; Panarchy; Resilience; Lake ecosystem; Natural resource management;

    Abstract : Liming has been used extensively in Sweden, but the management success has been only partial, mostly mitigating the impact of acidification rather than restoring the ecological communities to a self-maintaining pre-acidified state. Rather than a sound restoration tool, liming is a form of command-and-control management that comprises a significant disturbance in the system, which manifests in the form of profound alterations of biophysical settings of lakes.

  3. 2. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

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

    Author : Claes Sjöberg; Jens Kårhammer; [2021]
    Keywords : strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Abstract : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. READ MORE

  4. 3. Nutrient concentrations before and after the Focus on Phosphorus project in E23 catchment

    University essay from SLU/Dept. of Soil and Environment

    Author : Åsa Larsson; [2018]
    Keywords : phosphorus; Greppa fosforn; two-stage ditch; structure liming; sedimentation pond;

    Abstract : Between 2007-2014, as part of the Greppa Näringen, there was a subproject on phosphorus losses called Focus on Phosphorus (FoP; Greppa Fosforn). Previous measures on eutrophication mainly focused on nitrogen leakage, whilst the purpose of FoP was to test already known mitigation methods against phosphorus losses in the field. READ MORE

  5. 4. Kalkning på alkalina jordar : utan stallgödsel med sockerbetor i växtföljden

    University essay from SLU/Dept. of People and Society

    Author : Jacob Larsson; [2018]
    Keywords : kalk; alkalina jordar; strukturkalk; kalkstensmjöl; lönsamhet; fältförsök;

    Abstract : Fram till och med kampanjen 2016 så fanns det en reglerad marknad på odling av sockerbetor, men nu har man släppt på denna reglering vilket har bidragit till ett överskott på socker i världen. Detta har gjort att ekonomin i sockerbetsodlingar har sjunkit drastiskt de senaste åren. READ MORE

  6. 5. Strukturkalkningens effekt beroende på spridningstidpunkt, inblandningsdjup och kalkgiva

    University essay from SLU/Dept. of Soil and Environment

    Author : Johan Knutsson; [2018]
    Keywords : strukturkalk; kalkförsök; markstruktur; fosforläckage; näringsläckage;

    Abstract : Structural liming is something that will positively affect the hard clay soil in theory. This work should demonstrate that it is also so in practice. The purpose of this work was to study the effect on soil struc-ture after spreading structure lime at different time, different incorporation depths and different rates. READ MORE
