- •
Occlusion of organic carbon in phytolith (phytOC) is a mechanism for long-term C sequestration.
- •
PhytOC content and production in the above and belowground parts of steppe plants were determined.
- •
PhytOC concentration was significantly higher in below than above ground plant parts.
- •
PhytOC production was at least one order of magnitude greater from below than above ground parts.
- •
Belowground part plays a dominant role in biogeochemical silica cycle and C sequestration.
