| description | This study examines soil compaction and its effect on soil properties, how to
avoid compaction and how to regenerate damaged soil structures. One central
focus that the study deals with is what importance earthworms have in
soil compaction processes. The focus on earthworms is interesting because
they are important for the soil structure and therefore they play an important
role in soil compaction processes. Furthermore, the importance of earthworms
in soil compaction processes is yet an understudied area in agricultural
research and related applied studies. This study is based on existing
academic literature and applied studies on soil structure and soil compaction.
In addition to this, the study also presents novel information of practical
experiences which have been collected through interviews with professionals
in Sweden.
The main results show that soil compaction is an increasing problem and
that in the long term it will affect the quality of arable land, crop growth and
the environment. There is no specific factor that determines the degree of
compaction, however, there are several factors that together contribute to
different degrees of compaction. Soil compaction can be avoided and compacted
soils can be regenerated. This is an important insight as a good and
sustained soil structure leads to crop growth and relatively high yield potential.
The study also shows that earthworms positively influence soil structure
and thus contribute to alleviate the effects of soil compaction. Yet, soil compaction
also impacts negatively on earthworms and reduce the earthworm
populations. The role of earthworms in regeneration of compacted soils is
not straightforward. Overall, there is a need for knowledge about soil compaction,
how it can be avoided and how soils can be regenerate after compaction.
Since the importance of earthworms is unclear, it can be seen as
an indication that more studies that focuses on this is needed. |

I denna studie undersöks markpackning och dess effekt på markens egenskaper, hur man kan undvika packning samt regenerera en skadad markstruktur. Ett särskilt fokus är att förstå och förklara vilken betydelse som daggmasken spelar för markpackning. Ett fokus på daggmask är intressant eftersom den är viktig för markstruktur och har därav betydelse för markpackning. Därtill, daggmaskens betydelse i ett markpackningssammanhang är ännu ett outvecklat område inom agrar forskning och tillämpade studier. Denna studie baseras på existerande akademisk litteratur och tillämpade studier om markstruktur och markpackning. Utöver detta har det gjorts en särskild insamling av praktiska erfarenheter som samlats in via intervjuer med rådgivningsexpert vid Hushållningssällskapet och Jordbruksverket. De huvudsakliga resultaten från denna studie visar att markpackning är ett tilltagande problem och att det på sikt kommer att påverka åkermarkens kvalité, grödtillväxt och miljön. Det finns ingen specifik faktor som bestämmer graden av packning utan flera faktorer som tillsammans bidrar till olika packningsgrader. Studien visar att markpackning kan undvikas och att packad mark kan regenereras. Detta är en viktig insikt då en god och bibehållen markstruktur leder till grödtillväxt och relativt hög avkastningspotential. Studien visar även att daggmask påverkar markstruktur positivt och bidrar på så sätt till att lindra effekterna av markpackning. Markpackning påverkar daggmaskpopulationen negativt. Daggmaskens roll i regenerering av packad mark är inte entydig. Sammantaget finns behov av kunskap om markpackning, hur det kan undvikas och hur mark kan återställas efter packning. Att daggmaskens betydelse inte är entydig kan ses som en indikation på att det behövs fler studier som fokuserar på detta.
