description A healthy agricultural soil consists of a stress-resilient system due to its biological diversity, active nutrient cycling, and high physical stability. The activity of bacteria and fungi are the\nmost important components in the processes of humification and physical stability of the soil, being arbuscular mycorrhiza (AMF) the fungi that stand out. AMF synthesize a glycoprotein\ncalled glomalin predominantly present in the mycelium. The term GRSP (glomalin-related soil protein) is used to refer to the generic product of the pool of proteins extracted and\nquantified from the soil, being the most used to estimate the level of glomalins in a soil. The\ngeneral objective of the project is to evaluate the content of glomalin GRSP, produced by\nAMF, as a biochemical variable related to the productivity of soils with a low content of clay\nfraction, nutrients and structural fragility. The objective is to estimate the quantitative\nparticipation of GRSP in soil organic carbon, its impact on edaphic stability and the\nconsequences on the net primary productivity and quality of forage resources together with\nits ruminal and enzymatic digestibility. Four tests were carried out, three manipulative and one measurative under controlled and production conditions. The GRSP values presented a positive linear relationship with respect to the organic carbon in two different essays (R2=0,93 and R\n2=0,60), the GRSP / Cox values had a negative linear behavior with respect to the organic carbon (R2=0,71). In addition, a positive linear correlation was observed between the weighted mean diameter and GRSP (R2=0,59), the inoculation with AMF presented significant\neffects on GRSP (p<0.05), foliar phosphorus (p<0.05) and aerial biomass(p<0.1). No significant differences were observed in digestibility, ruminal degradability, fiber in acid detergent, fiber\nin neutral detergent and lignin in acid detergent for aerial biomass. These results indicate that GRSP could be considered a biological soil indicator, being the accumulation of soil carbon\nsimultaneous with the enrichment of GRSP. The GRSP content and the ratio of GRSP to organic carbon (GRSP / Cox) could be considered indicators of the soil structure. Inoculation with AMF spores generated significant increases in the contents of GRSP, aerial biomass and foliar\nphosphorus of Festuca arundinacea without the addition of fertilizer.

Buenos Aires, Argentina Ciarlo, Esteban Giuffré, Lidia Ferrero Holtz, Esteban Waldemar 2023-05-10 Un suelo agrícola saludable constituye un sistema con resiliencia al estrés debido a su diversidad biológica, ciclado activo de nutrientes y alta estabilidad física. La actividad de bacterias y hongos son los componentes más importantes en los procesos de humificación y\nestabilidad física del suelo, destacándose entre los hongos los micorríticos arbusculares (HMA). Los HMA sintetizan una glicoproteína denominada glomalina presente predominantemente en el micelio. El término GRSP (glomalin-related soil protein) se utiliza para referirse al producto genérico del pool de proteínas extraídas y cuantificadas del suelo siendo el más utilizado para estimar el nivel de glomalinas de un suelo. El objetivo general del proyecto es evaluar el contenido de GRSP, producida por los HMA, como variable bioquímica relacionada a la productividad de suelos con bajo contenido de fracción arcillas, nutrientes y fragilidad estructural. Se pretende estimar la participación cuantitativa de GRSP en el carbono orgánico del suelo, su impacto sobre la estabilidad edáfica y las consecuencias sobre la productividad primaria neta y calidad de recursos forrajeros conjuntamente con su\ndigestibilidad ruminal y enzimática. Se realizaron cuatro ensayos, tres manipulativos y uno\nmensurativo en condiciones controladas y de producción. Los valores de GRSP presentaron un comportamiento lineal positivo respecto del carbono orgánico en dos ensayos diferentes\n(R2=0,93 y R2=0,60), los valores de GRSP/Cox se relacionaron en forma lineal e inversa con el carbono orgánico (R2=0,71). También se observó una asociación lineal positiva entre diámetro\nmedio ponderado de los agregados (DMP) y GRSP\n(R2=0,59), y la inoculación con HMA presentó efectos significativos sobre GRSP (p<0.05), P foliar (p<0.05) y Biomasa aérea (p<0.1).\nNo se observaron diferencias significativas en digestibilidad, degradabilidad ruminal, FDA,\nFDN y LDA de la Ba. Estos resultados indican que GRSP podría ser considerado un indicador biológico del suelo, siendo la acumulación de C del suelo simultánea con el enriquecimiento de GRSP. El contenido de GRSP y la proporción de GRSP respecto del C orgánico (relación\nGRSP/Cox) podrían ser considerados indicadores adecuados de la estructura del suelo. La inoculación con esporas de HMA generó aumentos significativos en los contenidos de GRSP, Ba y P foliar de Festuca arundinacea sin agregado de fertilizante. application/pdf Suelo agricola spa Universidad de Buenos Aires.
