Appraising soil carbon storage potential under perennial and annual Chenopodiaceae in salt marsh of NE Spain

The work was conducted at La Pletera salt marsh (NE Spain) to investigate the potential for atmospheric carbon capture of perennial Sarcocornia fruticosa (L.) Scott and annual Salicornia patula Duval Jouve subsequent integration storage into S. soils respectively, 0–5 5–20 cm depth. amounts aboveground (aC), belowground (bC) litter (lC) were 2300%, 350% 3000% higher than according respective plant, root biomass. This dramatic difference reflected in soil organic (SOC) values, much depth with 17.07 ± 5.83 g kg?1 5.89 1.68 kg?1, namely 189% increase. Similarly, SOC increased by 109% species can accumulate great amount decaying debris surface, which would gradually decompose microbial activity increase stock. Furthermore, incorporated is better quality because contains fractions glomalin, a stable compound known its important role aggregate stability. In fact, glomalin related protein (GRSP) 292% 182% two depths respectively. By contrast, low nature produced are easily mineralized lesser consequently soil. Lower GRSP affected stability (WSA) 0.25–2 mm 2–5.6 fractions, considerably more detachable Moreover, this exhibited highest mineralization coefficient (Qm) both depths, 125% 175% major sensitivity loss. PCA further highlighted ability habitat act as sink. Results may be valuable vegetation management addressed mitigate climate change ecosystem services.
