Core Viewpoint - Sichuan province is under significant pressure to reduce fertilizer use while ensuring food security, as it is one of the 13 major grain-producing provinces in China and the largest producer of rapeseed [1][4]. Group 1: Agricultural Practices - Sichuan has initiated a green cycle agriculture pilot program focusing on organic materials for fertilizers, technological improvements for quality, and effective mechanisms for implementation [1][5]. - The province has successfully reduced chemical fertilizer usage by 2 pounds per acre compared to ten years ago, without affecting grain yields, which have consistently increased, reaching a historical high of 72.68 billion pounds last year [1][2]. Group 2: Challenges and Policies - The dual mission of promoting green agricultural development while ensuring food security presents a significant challenge for Sichuan, necessitating a balance between reducing fertilizer use and maintaining stable crop yields [3][4]. - National policies initiated in 2015 aimed at zero growth in fertilizer usage have placed additional pressure on provinces like Sichuan to meet environmental and agricultural standards [3][4]. Group 3: Innovative Approaches - The green cycle agriculture pilot program emphasizes the use of organic waste, such as livestock manure and straw, to enhance soil fertility and reduce reliance on chemical fertilizers [5][6]. - Technological innovations in fertilizer application, including new fertilization techniques and products, have been implemented in major grain-producing counties, leading to a zero growth in fertilizer usage for three consecutive years in some areas [6][8]. Group 4: Future Directions - Moving forward, Sichuan's agricultural strategy will focus on improving fertilizer efficiency rather than merely reducing quantities, with an emphasis on scientific fertilization practices [8][9]. - The province plans to enhance the utilization of organic fertilizers and expand the coverage of soil testing and tailored fertilization techniques to ensure sustainable agricultural practices [8][9].
