- •
Biocrusts strongly protect soil from water erosion and reduce TOC losses.
- •
Well-developed biocrusts are more effective in decreasing sediment yield and TOC loss.
- •
Sediment yield increased up to 20 times after biocrust removal.
- •
89% of annual TOC mobilization occurred during the first rain after biocrust removal.
- •
Rainfall properties greatly influence sediment and TOC losses in biocrusted soils.
