Tillage effects on carbon footprint and ecosystem services of climate regulation in a winter wheat–summer maize cropping system of the North China Plain

Summary

This field study examined how tillage intensity influences both the carbon footprint of production and the climate regulation ecosystem services provided by soils in a dual-crop winter wheat and summer maize system typical of the North China Plain. The authors appear to have compared conventional and conservation tillage approaches to identify trade-offs or synergies between reducing production emissions and enhancing soil carbon sequestration. The work contributes to understanding how agronomic practice choices affect net climate impact across the full production cycle.

Regional applicability

The North China Plain context (semi-arid, intensive cereal production, high mechanisation) differs substantially from United Kingdom temperate maritime conditions and crop mix. However, the methodological approach to integrating lifecycle carbon assessment with soil carbon accounting and ecosystem service valuation is transferable; UK researchers investigating tillage impacts on winter cereals or mixed arable systems could adapt this framework, though local soil types, climate, and crop sequences would necessitate separate field trials.

Key measures

Carbon footprint (likely lifecycle GHG emissions), soil organic carbon, carbon sequestration rate, ecosystem service valuation for climate regulation

Outcomes reported

The study assessed how different tillage practices (likely conventional vs. conservation/no-till) affected the carbon footprint and ecosystem service value of climate regulation in a winter wheat–summer maize rotation. Metrics probably included greenhouse gas emissions, soil carbon storage, and economic valuation of climate regulation services.
