Effect of Nitrogen Source on Some Rhizospheric Properties and Persistence of my Corrhizal Fungal Propagules in an Andisol Chilean J. Agric. Res.
Cornejo,Pablo; Rubio,Rosa; Borie,Fernando.
Nitrogen fertilization influences plant growth and rhizospheric properties, affecting the functionality and persistence of arbuscular mycorrhizal fungi (AMF). In order to analyze the effect of two N-sources (NH4+ and NO3-) on the persistence of AMF propagules (colonized root, mycelium and spores) and some rhizospheric parameters (pH, P available), a greenhouse experiment was carried out using two wheat (Triticum aestivum L.) cvs. Otto and Metrenco, which were grown in an Andisol. Plant biomass was determined at the dry grain stage (Zadocks 99, 150 days after sowing, DAS), the density of AMF propagules was determined three months later (240 DAS), and pH and available P were determined at both stages. The results showed that N-source and cultivar influenced...
