Response of the Stability of Soil Aggregates and Erodibility to Land Use Patterns in Wetland Ecosystems of Karst Plateau
Summary
This is not about microplastics — it is a soil science study examining how different land use patterns in Chinese karst plateau wetlands affect soil aggregate stability and erosion rates.
The world’s natural wetlands, which have important ecological functions, are being lost at an alarming rate. The erosion and deposition of soil on wetlands is a major cause of wetland conversion to agriculture. An urgent problem to be solved is how to slow down the erosion and deposition of wetlands resulting from land use. Land use patterns affect soil properties, thereby affecting soil aggregate stability and erodibility. Evaluating the effects of land use patterns on soil aggregate stability and erodibility in small watersheds of wetland ecosystems of karst plateau is of great importance. Thus, we compared the soil properties, aggregate stability indicators and soil erodibility of shrubland, grassland, artificial forest land and sloping farmland for evaluating the impact of various land use patterns on soil aggregate stability and erodibility in typical karst plateau wetland ecosystems. Our results showed that the mass fraction of soil aggregates > 0.25 mm was the main component in the four land uses, with greater variation in aggregates > 5 mm; overall, MWD, GMD and WSA0.25 were higher in grassland and shrubland than in sloping farmland and artificial forest land, while K values, PAD and SCAI showed the opposite trend. Correlation analysis showed that effective soil nutrients had a positive effect on soil aggregate stability. In conclusion, the stability of soil aggregates and resistance to soil erosion were strongest under the influence of shrubland. Our study showed that shrubland can better improve soil aggregate stability and erosion resistance, which may provide a guide for protecting and restoring karst plateau wetland ecosystems.

Microplastics trapped in soil aggregates of different land-use types: A case study of Loess Plateau terraces, China
Researchers measured microplastic abundance in soil aggregates from four land-use types on China's Loess Plateau, finding MPs trapped in aggregates across all land uses with farmland soils having the highest concentrations. Woodland soils had the lowest MP content and the most stable aggregate structure, suggesting land use substantially controls both MP accumulation and aggregate integrity.
Cropping systems reshape the distribution and risks of microplastics in soil aggregates in a karst agricultural region
Researchers investigated how different cropping systems influence the distribution and ecological risks of microplastics within soil aggregates in a karst agricultural region. The study found that cropping system type reshaped microplastic abundance, morphology, and polymer composition across macro-, meso-, and micro-aggregate fractions, with implications for understanding microplastic persistence in fragile karst soils.
Impact of soil structure and texture on occurrence of microplastics in agricultural soils of karst areas
Researchers found that soil texture is the dominant factor influencing microplastic abundance in karst agricultural soils in China, with powdered-light clay soils harboring the highest contamination at nearly 3,000 particles per kilogram.
