Microplastic interactions in the agroecosystems: methodological advances and limitations in quantifying microplastics from agricultural soil
AI summary Read the abstract
This review examines how microplastics behave in agricultural soils and their effects on soil quality and crop growth. Researchers found that microplastics alter key soil properties like water retention, density, and microbial composition, and can make other pollutants like heavy metals more available to plants. The study also highlights gaps in current methods for isolating and identifying microplastics in soil samples.
The instantaneous growth of the world population is intensifying the pressure on the agricultural sector. On the other hand, the critical climate changes and increasing load of pollutants in the soil are imposing formidable challenges on agroecosystems, affecting productivity and quality of the crops. Microplastics are among the most prevalent pollutants that have already invaded all terrestrial and aquatic zones. The increasing microplastic concentration in soil critically impacts crop plants growth and yield. The current review elaborates on the behaviors of microplastics in soil and their impact on soil quality and plant growth. The study shows that microplastics alter the soil's biophysical properties, including water-holding capacity, bulk density, aeration, texture, and microbial composition. In addition, microplastics interact with multiple pollutants, such as polyaromatic hydrocarbons and heavy metals, making them more bioavailable to crop plants. The study also provides a detailed insight into the current techniques available for the isolation and identification of soil microplastics, providing solutions to some of the critical challenges faced and highlighting the research gaps. In our study, we have taken a holistic, comprehensive approach by analysing and comparing various interconnected aspects to provide a deeper understanding of all research perspectives on microplastics in agroecosystems.

AI summary Read the abstract
This review examines how microplastics enter and move through agricultural soil ecosystems, affecting soil properties, nutrient cycling, and the organisms that live in and depend on healthy soil. Researchers found that microplastics can alter key biogeochemical processes and interact with co-existing pollutants like heavy metals and pesticides, potentially compounding their harmful effects. The study highlights the need for prevention and control strategies as microplastic contamination of farmland becomes an increasingly recognized environmental and potential human health concern.
Microplastics in agroecosystems: A review of effects on soil biota and key soil functions
AI summary Read the abstract
This review examines how microplastic and nanoplastic contamination in agricultural soils affects soil organisms and ecological functions. Researchers found that plastics enter farmland through multiple pathways including plastic mulch, sewage sludge, and irrigation water, and once present they alter soil properties and exhibit toxic behavior toward soil biota. The study identifies significant knowledge gaps about the long-term impacts of microplastic accumulation on agricultural productivity and food safety.
