This study aimed to survey the long-term effects of fertilization practices on functional diversity soil microbiota. A 60-year experiment with mineral fertilizers, farmyard manure and combined treatments was sampled in two consecutive years maize ( Zea mays L.) wheat Triticum aestivum L.). Soil chemical properties, plant growth physiological parameters were measured. The MicroResp TM method applied assess community level profiles (CLPPs) rhizosphere soil, arbuscular mycorrhizal fungal (AMF) colonization roots determined. Samples taken early vegetative stages, at flowering, harvest both years. measured analysed using multifactorial ANOVA determine treatment effects, crop-dependent differences, seasonality. PCA analysis performed data matrix reveal more complex correspondences, Pearson’s product-moment correlation used confirm relationships between some parameters. Fertilization caused changes biological such as: parameters, citrate utilization, total substrate-induced respiration value, ratio utilization amino acids sugars. rate AMF responded mainly nutrition status requirements, suggesting a plant-mediated effect case mycorrhiza. Mineral nitrogen acidification found be main factors affecting catabolic activity microbiota, while balance nutrition.
