Researchers at University of Gloucestershire, UK to begin a study aimed to analyze the effects of plastic on soil biodiversity, function and productivity.
The project is being funded by EU and this area of study is relatively less explored by the scientists.
According to the project summary, plastic debris’ effects on soil health are largely unknown, although equal, or possibly greater, amount of plastic is mixing in the soils when compared to rivers, seas and oceans.
Working with partners across the farming community, MINAGRIS (MIcro- and Nano-plastics in AGRIcultural Soils) will conduct experiments in 11 case studies across Europe, including one in the UK.
As part of the study, the Countryside and Community Research Institute (CCRI) at the University of Gloucestershire will disseminate research findings, investigate advice available to farmers about plastic use in agriculture, and work with UK horticultural growers and partners.
Professor Julie Ingram, Associate Professor Jane Mills, and Dr Charlotte Chivers make up the CCRI team.
Plasticulture has left its positive mark in agriculture, but the negative effects of plastic on soil is something which needs to be looked at in depth.
Despite the importance of soil biodiversity, very little attention has been given to plastics’ impacts on soils, according to Ingram, who will lead the work in the UK.
“We look forward to supporting a team of highly experienced scientists across Europe to fully assess the environmental impacts of plastics on soil health, before exploring ways of reducing farmer reliance on products containing plastics.”
Plasticulture is being used in many forms in agriculture, such as, mulches, packaging, nursery bags, soil solarization etc. The impact of plastic debris in the soil, especially when combined with pesticides and pharmaceuticals, is unknown, however.
The intent of this project is to provide farmers and others with tools and guidance on how to assess their exposure to plastics and help them to shift away from plastic-based products once the impacts of plastics on soil health are established.
