Glomalin acts like little globs of chewing gum on strings or ...The highest glomalin content (1070 mg kg-1) was found in plots receiving a balanced nutrient mix of FYM and mineral fertilizers. There was a significant increase in glomalin content under all nutrient management treatments (T 2 -T 6) in soil over the control (T 1).Soil organic matter is the dominant carbon pool in terrestrial ecosystems, and its management is of increasing policy relevance. Soil microbes are the main drivers of soil organic carbon ...Scientists have estimated that soils—mostly, agricultural ones—could sequester over a billion additional tons of carbon each year. 4 This has led policymakers to increasingly look to soil-based carbon sequestration as a “negative emissions” technology—that is, one that removes CO 2 from the air and stores it somewhere it can’t ...glomalin (i.e. glycoprotein) produced by AMF is deposited on the outer wall of hyphae of extraradical mycelium and adjacent soil particle, acts as a long-term soil- 102 P. Panneerselvam et al.No tillage with straw return leaves residues to the soil surface, providing binding agent (such as glomalin content) for the formation of macro-aggregates (Borie et al., 2006). Furthermore, higher soil moisture and lower soil temperature under no tillage than conventional tillage are likely to slow down the degradation rate of organic residues and …Concentration of Glomalin Related Soil Protein is reportedly close related to soil functions, but few data is available for GRSP compositional variations and function related to soil properties.

P is easily absorbed from soil particles and therefore Pi-free zones are readily formed around the roots. Extraradical hyphae of the mycorrhizal roots extend beyond ...Glomalin is generally believed to be produced by a common soil microorganism that has a beneficial relationship with plant roots. The tongue-twisting name for this organism is arbuscular mycorrhizal fungi. An earlier study suggested that the glomalin extraction method might actually extract proteins from other sources. Steve Culman and his ...1. Introduction.
