Seasonal variation in winter wheat field soil arbuscular mycorrhizal fungus communities after non-mycorrhizal crop cultivation.
Mycorrhiza. 2018 Aug; 28(5-6):535-548.M

Abstract

Intensive farming practices that implement deep and frequent tillage, high input inorganic fertilization, cultivation with non-host species, and pesticide use are widely reported to be detrimental for arbuscular mycorrhizal fungi (AMF), which are one of the most important plant biofertilizers. The effect of the reduction of agricultural input on AMF community dynamics following conversion from conventional non-mycorrhizal to lower input mycorrhizal crop cultivation has not yet been fully elucidated. We investigated the effect of the reduction of agricultural input, rotation, and season on AMF communities in winter wheat field soil after conversion from long-term (more than 20 years) non-mycorrhizal (sugar beet) crop cultivation. We described AMF communities from bulk soil samples by specifically targeting the 18S ribosomal gene using a combination of AMF specific primers and 454 pyrosequencing. No effect was found after 3 years' reduction of agricultural input, and only marginal effects were due to rotation with specific crops preceding winter wheat. Instead, season and year of sampling had the most appreciable influence on the AMF community. We suggest that, after conversion from long-term non-mycorrhizal to mycorrhizal crop cultivation, AMF diversity is low if compared to similar agroecosystems. Seasonal and successional dynamics play an important role as determinants of community structure.
