Century-long mineral and organic fertilization shapes carbon dioxide emissions and methane oxidation in sandy soil

Summary

This long-term field study leverages a century-long fertilization experiment to evaluate how contrasting mineral and organic fertilization strategies shape soil greenhouse gas dynamics in sandy soils. The work suggests that prolonged fertilization regimes significantly influence both CO₂ emissions and the soil's capacity to oxidise methane, potentially offering insights into how fertilization choices affect soil carbon cycling and climate-relevant gas fluxes. The extended temporal scale provides rare evidence of century-scale soil responses to management.

Regional applicability

Poland's sandy soils share characteristics with similar coarse-textured soils found in parts of the United Kingdom (notably East Anglia and southern regions). Findings may be transferable to UK horticultural and arable systems on sandy or sandy loam soils, though UK's cooler, wetter climate and different cropping practices warrant local validation before direct application to policy or advisory recommendations.

Key measures

Carbon dioxide emissions (CO₂ flux), methane oxidation rates, soil properties under contrasting fertilization regimes over ~100 years

Outcomes reported

The study examined how a century of mineral and organic fertilization regimes influenced carbon dioxide emissions and methane oxidation capacity in sandy soil. Outcomes likely include quantified differences in CO₂ and CH₄ fluxes across fertilization treatments.
