- Description: A Chinese rotation study found species-specific bacterial and fungal responses, not a single generic 'soil-health' gain.

Evidence

Peer-reviewed

Geography

Guizhou Province, China

System

Agricultural rotation; rhizosphere microbial communities

## WHAT THE EVIDENCE SAYS

Researchers compared sorghum monoculture with rotations involving potato, vetch and green pea shoots. Soil nutrient profiles and fungal and bacterial assemblages responded differently by rotation, including an elevated relative abundance of Fusarium in the potato rotation.

## WHY IT MATTERS / OUR READ

Rotation is not a uniform ecological treatment. Nutrients, potential pathogens, real crop yields and management constraints should be assessed together.

## CAVEATS / UNCERTAINTY

Sequencing associations and predicted functions do not establish microbial activity, disease incidence, long-term yield benefits or an optimized rotation for other soils.
