Glomalin and Contribution of Glomalin to Carbon Sequestration in Soil: A Review

Arbuscular mycorrhizal fungi (AMF) improves the uptake of nutrients and water to plants through mutual symbiosis. Only AMF produces glomalin related soil protein (GRSP). Acaulospora morroaiae, Glomus luteum, verruculosum, versiforme are effective producing AMFs. Mixed primary forest, tropical rainforest, organic matter, clay soil, no tillage, quality quantity fertilizers, crop rotation, stable aggregates also suitable increase production. Glomalin is a glycoprotein that contains 30–40% carbon (C) which assumed be persistent in soil. The can sequestrate more due its high aggregate stability. Greater stability leads protection terrestrial ecosystems. lowest content (0.007 mg per gram soil) was found Antarctic region, highest (13.50 observed rainforest. In agricultural varies between 0.30 0.70 GRSP containing (SOC) deeper layers 1.34 1.50 times higher than surface layers. 0.24 Mg C ha-1 when present at 1.10±0.04 g-1. At elevated CO2 (700 µmol mol-1) level, easily extractable (EEG) total (TG) were 2.76 5.67% SOC layer over ambient dioxide (CO2) level. This finding indicates function sequestration under global environmental change scenarios. protect labile help regulating nutrient supply plants. No tillage practice causes hyphal length, (WSA) compared conventional practice. current review demonstrated an important tool for storage deep soils. mediates aggregates, quality, increases production, mitigates climate change.
