“…The glycoprotein known as glomalin-related soil protein (GRSP) is abundantly produced on hyphae and spores of arbuscular mycorrhizal fungi (AMF) in soil and in roots [ 6 , 7 ]. AMF and the typical secretion compounds of GRSP are well known for maintaining terrestrial ecosystems [ 8 , 9 ] because they contribute to the growth of plants, influence the compositions of plant communities, and participate in various soil processes [ 10 , 11 ]. GRSP could increase the stability of the soil organic carbon (SOC) pool, and its adhesive function could promote the formation of soil aggregates and improve soil quality [ 12 ].…”

The glycoprotein known as glomalin-related soil protein (GRSP) is abundantly produced on the hyphae and spores of arbuscular mycorrhizal fungi (AMF) in soil and roots. Few studies have focused on its amount, composition and associations with soil properties and possible land-use influences, although the data hints at soil rehabilitation. By choosing a primary forest soil as a non-degraded reference, it is possible to explore whether afforestation can improve degraded farmland soil by altering GRSP. In this paper, close correlations were found between various soil properties (soil organic carbon, nitrogen, pH, electrical conductivity (EC), and bulk density) and the GRSP amount, between various soil properties and GRSP composition (main functional groups, fluorescent substances, and elements). Afforestation on farmland decreased the EC and bulk density (p < 0.05). The primary forest had a 2.35–2.56-fold higher GRSP amount than those in the plantation forest and farmland, and GRSP composition (tryptophan-like and fulvic acid-like fluorescence; functional groups of C–H, C–O, and O–H; elements of Al, O, Si, C, Ca, and N) in primary forest differed from those in plantation forest and farmland (p < 0.05). However, no evident differences in GRSP amount and composition were observed between the farmland and the plantation forest. Our finding highlights that 30 years poplar afforestation on degraded farmland is not enough to change GRSP-related properties. A longer period of afforestation with close-to-nature managements may favor the AMF-related underground recovery processes.

The present study evaluated the efficiency of lignocellulosic agrowastes produced in Brazil as substrates for production of on farm AMF inoculum and tested different diluents and inoculation techniques. In a first experiment, Sorghum bicolor seedlings were colonized with Rhizophagus clarus or Claroideoglomus etunicatus and transplanted to 20 L bags containing sugarcane bagasse (SC), king palm leaf sheets (KP), or barley hulls (BH) mixed (1:1:1 or 2:1:1, v/v/v) with sand and rice shell. SC and KP were conducive for production of spores and infectious propagules. A number of infectious propagules obtained were greater than with BH and ranged from 233-350 propagules cm(-3) for both isolates in SC and KP at the1:1:1 mix dilution. Number of spores of both fungi was affected mainly by the SC agrowaste, and spore densities were significantly higher compared to KP and BH. In a second experiment, SC was mixed with soil or sand and inoculation consisted of transplanting colonized seedlings or adding soil inoculum. Number of propagules tended to differ for each fungus according to the inoculation technique or diluent. It is concluded from the data that SC and KP are suitable agrowastes to be incorporated in substrates for producing AMF inoculum using the on farm method.
