Towards Sustainable Management of Mineral Fertilizers in China: An Integrative Analysis and Review
Summary
This review examines strategies for sustainable management of mineral fertilizers in China, synthesizing research on improving nutrient use efficiency and reducing environmental impacts from fertilizer overuse. It is an agricultural science study unrelated to microplastics.
China has not only successfully fed 20% of the world’s population using only 9% of the world’s arable land; it has also become the world’s largest producer of various agricultural products. The widespread application of mineral fertilizers played a critical role in accomplishing this achievement. In this study, we conducted an integrative analysis of China’s mineral fertilizers over the last six decades from multiple perspectives—domestic production, consumption and international trade at national and international levels, and the agricultural use of fertilizers at a regional level. In addition, we quantitatively estimated fertilizer nutrient surpluses for 30 provinces in mainland China for the time period spanning from 1987 to 2018 and integrated the results as a reference to the evaluation of the implementation of the Zero Growth Action Plan regulating fertilizer use by 2020. We concluded that by 2019, 83% and 93% of the provinces had already achieved zero growth in fertilizer use and fertilizer nutrient surpluses, respectively. This shows promising potential for China in finalising the Zero Growth Action Plan of Fertilizers nationwide by 2020.

Comparative Study on the Use of Traditional, Conventional and Advanced Methodologies for Sustainable Agriculture – a Review
Not relevant to microplastics — this is a review comparing traditional, conventional, and nano-technology-based fertilisation methods in agriculture.
The Impact of Resource Spatial Mismatch on the Configuration Analysis of Agricultural Green Total Factor Productivity
This study analyzed how the spatial distribution of agricultural resources affects green farming productivity in China from 2005 to 2021. While not directly about microplastics, it found that pollutant emissions from fertilizers and petroleum products significantly hinder sustainable agriculture. The findings are indirectly relevant because agricultural plastic waste, including mulch films, is a major source of microplastic contamination in farmland soil.
Sustainable Plasticulture in Chinese Agriculture: a Review of Challenges and Routes to Achieving Long-term Food and Ecosecurity
This review examines the challenges of plasticulture in Chinese agriculture, where macro-, micro-, and nanoplastic pollution from mulch films threatens long-term soil health and crop production. The authors propose holistic solutions targeting plastic production, use, and waste management to protect food security.
The challenge of nanotechnology in the field of agricultural applications: Nanofertilizers as an emerging technology
This systematic review covers the development and applications of nanofertilizers — nano-scale nutrient delivery systems for agriculture — as an emerging and more efficient alternative to conventional fertilizers. Precision agriculture using nanotechnology could reduce the reliance on plastic-coated slow-release fertilizers that contribute microplastics to soil.
Occurrence and distribution of microplastics in organic fertilizers in China
Researchers surveyed microplastic contamination in organic fertilizers across China, finding widespread plastic particles in compost, manure, and biosolids, identifying fertilizer application as an emerging pathway for microplastic accumulation in agricultural soils.
