| Abstract (English): | This study examines the effects of organic amendments (OA) on arbuscular mycorrhizal fungi (AMF), soil properties, and wheat (Triticum aestivum L.) productivity. A field experiment (4 replicates) was conducted to assess the effect of two rates (100 and 200 kg N ha-1) of OA [chicken litter (CL), liquid pig manure (LPM), and digestate (DIG)], synthetic fertilizer (urea: U) as compared to an unfertilized control (Control). Fertilization (with the exception of LPM) reduced AMF root colonization at tillering but had no later-stage effects. The use of OA increased soil inorganic nitrogen concentration and microbial respiration at sowing, without affecting total organic carbon. The application of LPM was positively associated with soil pH, extractable phosphorus, electrical conductivity, and microbial respiration, suggesting enhanced nutrient availability and biological activity in the soil after its application, mainly at sowing. The abundance of AMF multiplied-spores was similar across treatments, although Control soils had three times more spores than fertilized ones. The diversity of AMF (Glomeraceae), assessed via SSCP gel electrophoresis was unaffected by fertilization but was slightly higher in OA-treated soils, excluding CL. Wheat productivity under OA was similar to that under U, but higher than in Control. Our findings suggest that OAs can sustainably enhance soil fertility and crop yield without harming beneficial fungal communities (focused on AMF), thus supporting their use as alternatives to conventional fertilization of wheat.

| Abstract (Spanish): | Se analizó la aplicación de enmiendas orgánicas (OA) sobre la actividad/diversidad de hongos micorrícicos arbusculares (AMF), la productividad en trigo (Triticum aestivum L.) y las propiedades edáficas. En un experimento de campo, se aplicaron (con 4 réplicas) 100 o 200 kg ha-1 de guano de gallina (CL), efluente líquido de cerdo (LPM), digerido (DIG), urea (U) y un control sin fertilizar (Control). La fertilización, excepto con LPM, redujo la colonización radical por AMF durante macollaje, sin efectos en estadíos posteriores. La aplicación de OA aumentó el nitrógeno inorgánico y la respiración microbiana, sin alterar el carbono orgánico total. La aplicación de LPM se asoció positivamente con el pH, fósforo extraíble, conductividad eléctrica y respiración microbiana, indicando aumento en nutrientes disponibles y actividad biológica en el suelo. La abundancia de esporas-multiplicadas de AMF no varió entre tratamientos, aunque Control presentó tres veces más esporas que los suelos fertilizados. La diversidad de HMA (familia Glomeraceae), evaluada por SSCP, no fue afectada por la fertilización, aunque fue ligeramente mayor en suelos con OA (excepto CL). La productividad del trigo fue similar entre todos los tratamientos fertilizados, superando a Control. Estos resultados apoyan el uso de OA, especialmente LPM, como alternativa sostenible a la fertilización convencional en trigo. [ABSTRACT FROM AUTHOR] |
