Selection and valorization of arbuscular mycorrhizal fungi isolated from phosphate sludge basins in promoting of citrus and carob seedlings

Accumulation of phosphate sludge (PS) generated from treatment process in the open air represent an environment risk and a problem terms storage capacities. The use this by-products agriculture, is alternative recovery technique for phosphate. Moreover, selection symbionts their inoculation into soil whether nursery or at field were strongly encouraged. These inoculants selected not only impact on plant, but also ability to persist expense residual native microflora. This can be performed microorganisms which could occur solid sludges deriving exploitation phosphates pilot site Khouribga area. In context, indigenous mycorrhizal resources have been exploited through better exploration local floristic diversity then series fungi production tests made. complex was prepared effect tested Citrus carob plants growth nursery. Two mixtures PS carried out: 10% (S2) 40% (S5) 20% (S3) plants. sandy Maamora forest used as control (S1). results shown three dominant morphotypes detected: Rhizophagus irregularis , Funnileformis constrictum Scutellospora calospora . with AMF-based inoculum indicate that substrates by raw stimulates specially S2, S5 S3 volkameriana, Carrizo citrange respectively. Based these results, combination between had great plant
