“…Total glomalin contents in soil have tight linkages to total soil organic matter (SOM) contents [11][12][13]. On the other hand, there is also evidence of a negative correlation between GRSP and SOM content [14].…”

The influence of different fertilizers (mineral/organic) on the quantity and quality of soil organic matter was monitored in long-term stationary experiments (27 years) with silage maize monoculture production on Luvisol. The main aim of this study was to investigate the relationship between easily extractable glomalin (EEG), total glomalin (TG), and parameters commonly used for the determination of soil organic matter quality, i.e., the content of humic acids (CHA), fulvic acids (CFA), and potential wettability index (PWI). A significant correlation was found between EEG content and CSOM content, humic acid content (CHA), humic acid/fulvic acid ratio (CHA/CFA), PWI, and index of aromaticity (IAR). Furthermore, the contents of EEG and TG correlated with soil organic carbon (CSOM). Periodical application of sewage sludge and cattle slurry increased the content of glomalin in soils. From the results, it is obvious that data about glomalin content can be used to study soil organic matter quality. A more sensitive method (a method that reacts more to changes in components of soil fertility) seems to be the determination of EEG rather than TG. The factors supporting use of EEG extraction in agronomic practice are mainly the substantially shorter time of analysis than TG, CHA, and CFA determination and lower chemical consumption. Furthermore, the PWI method is even suitable for studying soil organic matter quality. On the other hand, the humus quality ratio (E4/E6) does not provide relevant information about soil organic matter quality.

“…Mycorrhizal symbiosis is elemental to plant productivity and diversity and it is rare to find a situation in which AMFs are not of significant ecological importance. Its beneficial effects on plant nutrition and growth, as well as on the relief of biotic and abiotic stress, have been widely described (Souza et al, 2017;Diagne et al, 2020;Li et al, 2020;Singh et al, 2020).…”

“…For instance, "4 per 1000 Initiative: Soils for Food Security and Climate" was launched at COP21, with a global aspirational goal to increase SOC stock at an annual rate of 0.4 % per year in soils of all anthropogenic and natural land uses (Soussana et al, 2019). Total GRSP concentrations in soil certainly have a close link to total SOM concentrations (Li et al, 2020). Recent studies have shown that GRSP was the most important source of C in SOM-C (SOC) (Single et al, 2017;Whang et al, 2018;Zhang et al, 2017;Kumar et al, 2018).…”

Reducing soil degradation and its impacts on the environment have been one of the main challenges of the 21 st century, exacerbated by a direct link between increases in the human population and soil degradation that raises current and future food security concerns. Despite this, experiences worldwide reveal that degraded land restoration projects have either achieved little success or failed. Thus, understanding the underlying causes and devising appropriate restoration mechanisms is crucial. Soil amelioration using beneficial microorganisms, particularly arbuscular mycorrhizal fungi (AMF), is essential and pragmatic. Glomalin, a type of glycoprotein produced by arbuscular mycorrhizal fungi in the phylum Glomeromycota, contributes to the mitigation of soil degradation. Moreover, AMF and glomalin are highly correlated with other soil physico-chemical parameters and are sensitive to changes in the environment. As a result of this, they have been recommended for monitoring the recovery of degraded soil or stages of soil degradation. In this review, we discuss the role of AMF and glomalin in the restoration of degraded soils, including improvements to the soil structure and soil organic matter (SOM), microbial activity, reduction of fertility loss, bioremediation, and mitigation of the effects of drought and saline stress. We highlight the research gaps and discuss the prospects. This knowledge will improve our understanding of the ecological conduct of glomalin and AMF, stimulate future research, and be useful to sustainable restoration of degraded lands. Furthermore, we discussed the challenges and obstacles in the legislation and future perspectives on the production of inoculants based on AMF in Brazil.

“…[13,14] AMF also effectively prevent the loss of soil organic carbon (SOC) by stabilizing the soil particles. [15,16] In addition, AMF influence other soil microorganisms through variations in root exudation and plant carbohydrate metabolism. [17] AMF community structures and diversity have been found to be affected by agricultural management measures such as intercropping systems [18] and soil properties).…”

The variations of rhizosphere soil arbuscular mycorrhizal fungi (AMF) and their impact mechanism are still unclear under different intercropping systems in the Yellow River Irrigation District of Ningxia, China. A field experiment to study variations in rhizosphere soil AMF diversity and its effects under different planting systems in this area. Three intercropping systems consisting of six rows of spring wheat intercropped with two rows of soybean (RSW), wheat monoculture (RW), and soybean monoculture (RS) were applied. The results showed that the RSW treatment has a 5.6% and 10.0% higher soil organic carbon (SOC) content than the RW and RS plots, respectively. The dominant genera in this study are Glomus and Paraglomus. The Shannon index, Simpson index, Chao1 value, and abundance-based coverage estimator in the RSW treatment are higher than in the RS plots. Additionally, the multiple linear regression equation suggests that invertase activity is the main impact factor for the Shannon index of AMF. Moreover, the wheat yield in the RSW plot is 11.4% higher than the RW plot. The results suggest that the RSW treatment has great potential for improving soil nutrients, AMF diversity, and wheat yield to sustain soil health and crop production.
