Identifying Amf-Rich Tir Wheat Rhizospheres To Foster Microbial Inoculants Useful in Sustainable Agriculture: Evidence From the Van Lake Basin

Abstract

Arbuscular mycorrhizal fungi (AMF) play a pivotal role in sustainable agriculture by enhancing nutrient efficiency and reducing the dependence on synthetic fertilizers. Developing these sustainable, effective products requires knowledge of the target plant and its associated microbial communities in the production landscape of interest. This study focused on AMF populations associated with Tir wheat in six main locations of T & uuml;rkiye's Van Lake Basin. The Er & ccedil;ek-& Ouml;zalp-Saray region exhibited the highest organic matter values. Higher available phosphorous contents were found for Erci & scedil;-Patnos and Muradiye. The Erci & scedil;-Patnos region exhibited the highest AMF density (120 spores/10 g soil) and frequency (75%), while the lowest AMF density (45 spores/10 g soil) was recorded in Muradiye. Sand contents correlated positively with spore number and mycorrhizal frequency and negatively with silt and clay. Based on these results, Erci & scedil;-Patnos was elected as the best location for the isolation of AMF spores suitable for the development of microbial-based tools for Tir wheat cultivation. These results are very important in the current context of climate change, which mandates the use of low-impact environmental strategies. Further research should explore the interactions of AMFs with other microorganisms to optimize their ecological benefits. However, the results of this study provide a valuable basis for future investigations of AMF-based products for use in sustainable Tir wheat cultivation.
