Special Issue Information

Dear Colleagues,

Agricultural systems are significant sources of greenhouse gas (GHG) emissions (e.g., methane from livestock and nitrous oxide from fertilizers) and vital carbon sinks through soil sequestration and biomass storage. Globally, agriculture contributes 10–15% of anthropogenic GHG emissions, with regional variations driven by production types and land-use changes like deforestation. China’s "dual carbon" goals (peak emissions by 2030, neutrality by 2060) underscore the urgency of integrating agricultural mitigation strategies with food security needs. In recent years, non-point source pollution (NPSP) control has become central to green transformation. Through measures like fertilizer reduction and waste recycling, China has achieved milestones such as 88.1% straw utilization, 76% livestock manure recycling, and 80% agricultural film recovery rates.

This Special Issue calls for interdisciplinary research that advances the synergy between agricultural productivity and carbon neutrality, with a specific focus on cutting-edge technologies (e.g., soil carbon sequestration, methane mitigation, and circular agroecosystems), non-point source pollution control through ecological interception, pesticide reduction, biodegradable alternatives, and management innovations:

Original research articles and reviews are welcome. Topics of interest include, but are not limited to, the following:

  • Response analysis of ANPSP in watersheds;
  • Risk assessment of ANPSP;
  • Nature-based solutions (NbS);
  • Soil carbon sequestration;
  • Planting and breeding combination model;
  • Carbon sequestration accounting of agricultural ecosystems;
  • Machine learning-based predictive modeling

Rainfall-adapted irrigation (RAI), the application of controlled-release nitrogen fertilizer (CRNF), and deep placement of nitrogen fertilizer can contribute to the improvement of resource utilization efficiency. Nevertheless, the interactive effects of these factors on nitrogen loss via runoff and leaching from paddy fields remain ambiguous. Consequently, a two-year field experiment was conducted to evaluate the interactive effects of four nitrogen management strategies on nitrogen losses through runoff and leaching from paddy fields and rice yield under RAI when compared to conventional flooding irrigation (CI). Compared to CI, RAI significantly reduced total nitrogen loss via runoff (−49.8%) and leaching (−35.9%) by lowering volume of runoff and leaching. Compared to conventional nitrogen application (surface application of common urea with 240 kg N ha−1), deep placement of CRNF with 192 kg N ha−1 decreased floodwater nitrogen concentration, reducing total nitrogen loss by 46.8% via runoff and 50.9% via leaching. Importantly, RAI combined with deep placement of CRNF with 192 kg N ha−1 minimized nitrogen losses through leaching and runoff from paddy fields and maximized grain yield (8251 kg ha−1) by improving nitrogen accumulation in rice. Collectively, RAI combined with deep-placed CRNF with an 80% nitrogen rate could reduce non-point source pollution from paddy fields. Full article
