To scrutinize the contribution of agricultural plastic covers to plastic pollution, we quantified soil-associated plastic debris (≤ 2 mm) in and around agricultural fields covered with different plastics. PP fleeces and 50 µm thick PE films did not emit significant amounts of plastic debris into soil during their 4-month use. However, thinner and perforated PE foils (40 µm) were associated with elevated PE contents of up to 35 mg kg⁻¹. Their long-term use may thus favor plastic accumulation.
