Baseline levels of microplastics in agricultural soils obscure the effects of additional microplastics from recycled fertilizers

Microplastics and Nanoplastics
Digestate from the recycling of various organic wastes in biogas plants is widely used as organic fertilizer for agricultural soils. Organic fertilizers contribute to microplastic loads, but it is not well constrained how they contribute to the overall ...
