Plastic is a major environmental pollutant that has reached every ecosystem of the world by various means. Its unique properties (e.g. low cost, light weight) made it popular and part of daily life globally. This persistent pollutant of the planet can be divided into three types based on particle size: macroplastics (>5 mm), microplastics (between 5 mm and 1 μm), and nanoplastics (<1 μm). The scientific studies on microplastics (MPs) made it official that terrestrial ecosystems are a sink for MPs along with marine, freshwater, and atmospheric ecosystems. Soil MP pollution is increasingly gaining importance as MPs show difficulty in degradation, interact with other soil pollutants, and affect the physical, chemical, and biological properties of soil. Land use patterns are directly associated with human activities and have a huge impact on soil microplastic pollution and its distribution. Major concerns are regarding agricultural cropped lands, as they are directly related to food security and human health. This chapter gives a comprehensive overview of sources, types, and pathways of soil MPs; influence of agricultural activities, urbanization, industrialization, and landfill mismanagement on soil MP pollution; spatial distribution and concentration of MPs in different land use types; soil properties and management practices influencing MP pollution; and future directions and research needs to deal with soil MP pollution.
