The use of plastics in agriculture can have harmful effects on a wide range of ecosystem areas due to the resulting higher accumulation of micro- and nanoplastics in the soil. In this project, the use of plastics in agriculture, for example in vegetable cultivation and after long-term compost application, will be investigated in more detail. The goal of this project is to obtain more accurate data on the degree of pollution of agricultural land with plastics, as well as to facilitate the use of more sustainable plastics in agriculture in the future.
Although the use of plastics in agriculture brings many benefits, it also poses dangers because the fields are polluted by the plastics. The tiny particles of various micro and nano plastics are ingested by various organisms. The uptake can endanger the nutrient cycle, plant growth or biodiversity. One goal of the MINAGRIS project is to research the use and impact of plastics in agriculture and to work out how to use plastics in agriculture in a more sustainable way. The findings will be discussed with farmers, businesses and policy makers and pave the way for the sustainable use of plastics. A cornerstone of the MINAGRIS strategy is to provide an overview of the intentional and unintentional use of plastics in European agriculture and an accurate estimate of the pollution levels of plastics in agricultural soils.
In the Austrian case study sites Marchfeld and Alpenvorland 20 farmers were interviewed about the use of and possible contamination with plastics on their farms. Furthermore, soil samples were taken from two fields per farm. These were analyzed for macro- and microplastics.
