Research gap analysis derived from 3 agriculture papers in our local library.
The gap
Few studies have revealed MPs in soil as a result of wastewater irrigation, despite the increasing application of wastewater irrigation and inadequacy of conventional wastewater treatment plants in removing microplastics (MPs).
Evidence profile
Sourced from the future-work section and stated research gap and abstract of the source papers, classified as general, drawn from work published between 2025 and 2026, spanning 2 journals. Those papers have been cited 40 times in total.

Field-relevant degradation data for tropical high-altitude soils remain scarce. The gap is framed by the lack of understanding of how the physicochemical properties and microbial context of high-Andean soils affect the biodegradability of starch-based bioplastic films.
