Summary

This long-term field study examines how four decades of continuous cotton cropping under different soil management regimes—including fertilisation strategy, tillage intensity, and cover crop use—shape fungal soil communities. As one of the longest continuous monoculture experiments, the work provides evidence on whether conservation practices (reduced tillage, cover cropping) and nutrient management influence soil fungal assemblages under cotton cultivation. The findings suggest potential pathways by which agronomic management affects soil biological health in intensively cropped systems.

Regional applicability

This study was conducted in the United States, likely in a cotton-growing region, and direct applicability to United Kingdom arable practice is limited given the UK's temperate climate and different cropping portfolios. However, the methodological approach to assessing soil fungal responses to long-term monoculture management regimes may inform UK soil health monitoring frameworks and the impact of tillage and cover cropping on soil biology in cereal-dominated systems.

Key measures

Fungal soil community structure, diversity, and composition; effects of fertilisation regime, tillage practice, and cover cropping treatment over 41-year period

Outcomes reported

The study assessed changes in soil fungal community composition and diversity across 41 years of continuous cotton production under varied fertilisation, tillage, and cover cropping treatments. As suggested by the title, the research measured fungal soil communities as a proxy for soil health response to agronomic management.
