Abstract

Microplastic (MPs), a new pollutant, has been indicated to be contaminant in agricultural soils that affects plant growth. Despite the fact, studies on interaction between MPs-contaminated soils and potato growth involving bioremediation agents are limited. This study investigated the effectiveness of microorganisms (“Mn” brand), earthworms (“Ef ”), and two types of organic fertilizers (“SG” – conventional organic fertilizers and “Pa” – natural mineral organic) as an effort to provide healthy potatoes, especially minimal MPs, in achieving the Sustainable Development Goals (SDGs). Seven different treatments were applied: (P0) control – chemicals fertilizer, (P1) chemicals fertilizer + MPs, (P2) chemicals fertilizer + MPs + “Mn,” (P3) chemicals fertilizer +MPs + “Ef,” (P4) chemicals fertilizer + MPs + “Mn” + “SG” fertilizer, (P5) chemicals fertilizer + MPs + “Ef ” + “SG” fertilizer, and (P6) soil with “Pa” brand – natural mineral organic fertilizer. “Pa” is used to find alternatives to replace conventional organic fertilizers contaminated with MPs. This research has limitations because MPs are only in millimeter (mm) size. The observation 100 d after planting showed: (i) a combination treatment of conventional organic fertilizer and earthworm (P5) have improved potato biomass, total chlorophyll, tuber weight, tuber count, and three classes of tuber size significantly compared to other treatments, (ii) organic mineral fertilizer (P6) was unable to support organic potato cultivation, and (iii) MPs in mm size have disrupted potato production. It is recommended for future research as follows: (i) increasing the dose and frequency of application of earthworms and microorganisms, (ii) a combination of earthworms and microorganisms to increase synergy for minimizing the negative impacts of MPs. © (2023), (ResearchersLinks Ltd).
