Glomalin-related soil proteins (GRSP) are an important microbial carbon source for organic (SOC) and can also protect SOC by promoting the formation of aggregates. However, there is a lack systematic research on how contribution GRSP to changes during grassland degradation restoration. This study analyzed in SOC, total glomalin-related protein (GRSPt), easily extractable (GRSPe) contents, ratios GRSPe/SOC GRSPt/SOC at different aggregate fractions 0–10 cm 10–20 layers process restoration (from natural Sogong grass patches→degraded bare patches→transitional weed patches→naturally restored patches/artificially patches), explore scale succession.

Basic inventory is required for proper understanding and utilization of Earth’s natural resources, especially with increasing soil degradation species loss. Soil carbon newly refined at >30,000 Gt C (gigatonnes C), ten times above prior totals. organic (SOC) up to 24,000 C, plus plant stocks ~2400 both above- below-ground, hold >99% biomass. On a topographic surface area 25 Gha mean 21 m depth, has more than all trees, seas, fossil fuels, or the Atmosphere combined. Soils are greatest biotic store most active CO2 source. Values raised considerably. Disparity due lack full depth survey, neglect terrain, other omissions. Herein, totals mineral soils, Permafrost, Peat (of forms ages), determined (easily doubling shallow values), then terrain that ignored in terrestrial models (doubling values again), SOC recalcitrant glomalin (+25%) friable saprock (+26%). Additional factors include inorganic (SIC some origin), aquatic sediments (SeOC), dissolved fractions (DIC/DOC). biota (e.g., forests, fungi, bacteria, earthworms) similarly upgraded. Primary productivity confirmed >220 C/yr on land supported by Barrow’s “bounce” flux, C/O isotopes, glomalin, Rubisco. Priority issues extinction, humic topsoil loss, atmospheric remedied restoration biomass recycling via (vermi-)compost 100% husbandry under Permaculture principals, based upon Scientific observation Nature.

Glomalin-related soil protein (GRSP) are a glycoprotein mainly produced by arbuscular mycorrhizal (AM) fungi. GRSP deposited in the after being released from AM fungal hyphae, and they believed to improve health carbon (C) storage. However, it is unclear how fertilizer mycorrhiza suppression affect content of easily extractable (EE-GRSP) total glomalin-related (T-GRSP) arid grassland soil. We conducted 3-yr situ study determine main interactive effects nitrogen (N), phosphorus (P), fungicide (benomyl) addition on EE-GRSP T-GRSP desert steppe Northwest China. To further explore mechanisms influencing content, plant community, fertility traits were also identified. Following 3 years application, P had negative influence (−12.50%), whereas N no significant effect. Fungicide application reduced (−18.47%) (−18.36%) regardless addition. By altering extraradical hyphal length fungi, decreased without affecting vegetation or characteristics. Overall, this provides insights into dynamics response nutrient enrichment resource-limited ecosystem.

Phytoremediation of petroleum-contaminated soils using the synergistic functions plants and rhizosphere microorganisms is a promising technology. However, successfully applying this approach presents challenges under certain conditions (submerged environments). This study analyzed potential role Phragmites australis in symbiosis with arbuscular mycorrhizal (AM) fungi during petroleum remediation at two water levels. AM inoculation promoted P. aboveground growth non-flooded conditions, whereas flooding significantly increased biomass. The highest total hydrocarbon (TPH) degradation efficiency was observed soils, submergence severely inhibited TPHs dissipation. Plants treatments substantially enhanced removal flooded conditions. TPH positively correlated dehydrogenase activity but negatively easily extracted glomalin-related soil proteins. Moreover, different petroleum-hydrocarbon-decaying candidates contributed to these cultured soils. These findings provide valuable information for future TPH-contaminated especially applied intermittently submerged environments.
