文摘
- •
Covering plant species primarily influences soil water repellency and its markers.
- •
Single long-chain soil water repellency (SWR)-markers positively correlate to SWR.
- •
Root-derived ω-hydroxy fatty acids and α,ω-dicarboxylic acids predict SWR well.
- •
The corresponding biomarkers of the SWR predictors are abundant in grass roots.
- •
Grass roots mainly contribute to the organic matter in topsoils leading to strong SWR.
