PROLAND – Protecting agricultural lands from plastic pollution
End: jun 2026
Start: apr 2023
PROLAND addresses the sources of plastic pollution in agricultural soils: sewage sludge, compost, biogas digestate, agricultural plastics, and atmospheric deposition. The project unfolds pressures of plastic and associated chemical hazards by analyzing their levels in soils and conducting fate and impact studies. It deploys cutting edge “design thinking” methods to co-develop measures for pollution prevention.

The main aim of the project is to reduce plastic pollution in agricultural soils of Norway, and beyond.
At NIBIO, we investigate what happens to plastics in soil, to what extent different organisms in soil are exposed to microplastics, and the effects. Knowledge of exposure and toxicity is essential for assessing risk, and our main goals are to increase knowledge about:
- Mobility of microplastics and adsorbed pesticides and additives in different soil types
- Factors that influence exposure to microplastics in soil organisms
- Toxicity of microplastics and adsorbed pesticides and additives towards soil organisms
We are also contributing to our research partners' work related to:
- Mapping sources of plastic in agricultural soils (WP1, led by Rachel Hurley, NIVA)
- Determining concentrations of (micro)plastics and their additives in agricultural soils (WP 2, led by Sissel Ranneklev, NIVA)
- Collecting information from stakeholders about their challenges with agricultural plastics (WP4, led by Birgitta Ralston, BioRegion Institute)

Abstract
Funn fra PROLAND: Soppmidler og mikroplast i jorda Forskerne i PROLAND-prosjektet har undersøkt hva som skjer når soppmidler enten adsorberes på bionedbrytbar plastfolie som blir pløyd ned i jorda, kontra at de blandes direkte i jorda. Har dette noe å si for nedbrytningen av soppmidlene? Forskerne har fulgt nedbrytningsforløpet til tre soppmidler tillatt i norsk landbruk, og har nå svaret… Vi får også et unikt innblikk i hvordan meitemarken – naturens egen jordbearbeider – påvirkes av mikroplast. Hvor lang tid tar det for eksempel før en mikroplastpartikkel passerer gjennom meitemarkens tarm? Temaet er kanskje lite delikat på selveste valentinsdagen, men passer utmerket for oss som er nysgjerrige på mikroplastens mobilitet i jorda.
