Decades ago, microplastic presence was corroborated in aquatic ecosystem, but revelations from current studies indicate microplastics (MPs) as ubiquitous environmental concern and demonstrate our plasticized life, because of microplastic existent in food, air, water, and soil. Existence of MPs in terrestrial ecosystem is long recognized now and additionally, all the evidence that has been found for microplastic entering the farm soils indicated that they are gradually accumulating in the agricultural soil. While previous studies focused extensively on marine systems, the increasing toxicity of MPs in agricultural cultivated soils and the aspects of MPs being accumulated causing bio-toxification are being looked upon presently. They potentially damage the yield of crop plants making their roots unable to uptake water and nutrients from the soil by accumulating near the roots. MPs have already invaded the terrestrial food chain and they have been detected in excreta of livestock animals along with earthworms and crop plants. MPs are abundant in farm soil that has interacted with sewage-sludge, plastic mulching sheets, organic fertilizers, and vermicompost for a long duration. This review focuses on current evidence of microplastic accumulation in farm soil, thereby enlightening the potential damages to crop plants, soil properties, soil microbes while ultimately reaching humans via the food chain. It also covers the recent advances for soil microplastic extraction, treatment, and possible bioremediation strategies.
