Huadong Zang
China Agricultural University
Huadong Zang works as an associate professor at China Agricultural University (CAU) since 2019. Before joining CAU, he obtained his PhD at the University of Goettingen in 2018 and worked as a PostDoc at Bangor University. He has wide experience in agronomy and soil science, and extensive experience in 13C natural abundance techniques and multiple stable/radioactive isotope (13C, 14C, 15N, 18O) labeling approaches. His past research focused on N and C cycles in the plant-soil system, specifically on how N fertilization, temperature, and crop management influence C sequestration, organic matter stabilization, turnover, and priming effects in the agroecosystem. His current research interests are in investigating C and nutrient cycling, as well as plant-plant and plant-microbial-soil interactions in diversified cropping systems and agroecology. In his work he uses a combination of methods including on-station and on-farm experiments, isotopic labeling, zymography, and molecular techniques.

Shaoliang Zhang
Northeast Agricultural University
Dr. Zhang's research explores the spatiotemporal interactions between soil plastics/microplastics, soil nutrients, soil erosion, and biodiversity in agricultural fields at a range of scales. In particular he is focusing on questions of (1) how these interactions between soil nutrients, microplastics and biodiversity drive the succession of agricultural ecosystems, and how this knowledge can be used to restore agricultural ecosystems; (2) how do plastics get distributed in agricultural ecosystems, and how can we increase the efficiency of plastic degradation in agricultural soils. He has explored simple methods for the extraction and identification of light density microplastics from soil (STOTEN, 2018, 616–617, ESI), detected the movements, degradation, and distribution of microplastics in Mollisols, and reviewed the analytical methods, distribution, and biological effects of microplastics in terrestrial and marine ecosystems (TREND ANAL CHEM, 111, 2019, 62-72, ESI; JHM 2020, 124525). He received his PhD in Ecology from the Northeast institute of geography and agroecology, CAS, and is currently a full professor in the College of Resources and Environment, Northeast Agricultural University.

Wenqing He
China Academy of Agriculture Sciences
Dr. Wenqing He is a Professor at the institute of Environment and Sustainable Development in Agriculture, China Academy of Agriculture Sciences (CAAS), and the Principal Investigator of the agricultural plastic film research innovation team, CAAS. He holds degrees from Inner Mongolia Agricultural University and China Agricultural University. He has been engaged in the research of dryland farming and water saving agriculture for 16 years. His current research focuses on the application of agricultural plastic films and the prevention and control of mulch film residue pollution. His research has shown that mulch plastic films play a very important role in the production of dryland farming and that contamination caused by plastic film residue is a serious hazard for crop growth and soil health. In the past few years, Dr. He has undertaken and participated in more than 10 projects related to agricultural plastic film research including programs for the National Natural Science Foundation of China, Chinese National Programs for High Technology Research and Development and National Science and technology support programs, etc. He has also published 57 papers (14 papers are included in SCI/EI as the first author or corresponding author) and 3 books as chief editor and received four provincial-level Scientific and Technological Progress Awards.

Shibin Liu
Chengdu University of Technology
Shibin Liu is an Associate Professor at Chengdu University of Technology. He got his Master’s degree from Northwest University of Agriculture and Forestry and his PhD degree from the Department of Soil Science of Temperate Ecosystems, University of Göttingen. Dr Liu’s research focuses on the mechanisms of soil degradation and restoration. His main research areas include: (1) Effect of grassland degradation and subsequent restoration on soil properties and plant characteristics in the Tibetan Plateau. (2) Influence of organic fertilizer and its pyrolyzed biochar on soil biochemical properties and plant growth; (3) Fate and environmental behaviors of soil contaminants (e.g. heavy metals, microplastics and organic pollutants) and mechanisms of their remediation. Various methods (i.e. zymography, isotope labelling, 16S sRNA sequencing and so on) are involved in these studies.
Plastics are widely used in our daily lives and subsequent disposal exceeds 280 million tons annually. Despite plastics providing remarkable benefits, the vast amount of plastic waste entering the ecosystem is cause for concern. Plastic mulch films are widely used in agroecosystems to improve water use efficiency and crop yields, but they are notoriously difficult to recover from soil and are rarely recycled after crop harvest. Consequently, the remaining plastic films fragment into microplastics (MPs, <5 mm) through tillage, physical abrasion, and UV irradiation. We need a better understanding of MPs behavior in soils to to make informed policy decisions relating to the use and disposal of agricultural plastics.
This collection aims to provide researchers with novel methods and up-to-date researches related to MPs sampling, collection, and analysis, as well as its potential environmental impact in agroecosystems. The contributions can include but are not limited to methods and researches regarding MPs identification, transformation, movement and distribution in the agroecosystem, the effect of MPs on plant and soil health, and the interaction of MPs and other global change factors.
