“…Additionally, the positive relationships between all the AMF parameters and the shoot P/soil P ratio backs up this relationship between P acquisition and AMF. These results are in agreement with our second hypothesis and confirm other CC studies ( White and Weil , ; Isobe et al, ) that showed positive correlations between shoot P and AMF parameters. Although maize yield response to early P absorption is high ( Bittman et al, ), maize after barley did not show larger yields or biomass at harvest in our study.…”

Cover crops (CCs) provide ecosystem services to agricultural systems by soil health enhancement. However, the long‐term legacy of CCs on arbuscular mycorrhizal fungi (AMF) and subsequent main crop performance is unclear. The main objective of this work was to assess the 8‐year legacy of CCs on AMF activity and several soil and plant parameters during a subsequent maize (Zea mays L.) crop. The study was conducted in a field experiment established in 2006 under Mediterranean climate. Winter treatments were fallow and two CCs, barley (Hordeum vulgare L.) and vetch (Vicia sativa L.). We chose four sampling dates during maize development to evaluate the effect of CCs on AMF over time. Compared with fallow treatment, barley CC increased mycorrhizal colonization by 7%, the hyphae length by 39–124%, and AMF spores by 48–87%. However, contrary to expectations, vetch CC did not have any effect on AMF. Overall, earlier sampling dates better displayed treatment differences. Mycorrhizal colonization percentage demonstrated time‐sensitive values, whereas other AMF parameters (hyphae length, AMF spores) better maintained treatment differences over time. Mycorrhizal stimulation after barley increased maize shoot P concentration but shoot N was not increased despite the N deficit. Soil water stable aggregates were enhanced by barley CC (25–51% higher than fallow), notably related to the length of hyphae, AMF spores and glomalin content. Promotion of soil aggregation, nutritional state and plant height by CCs did not translate into maize yield increments. The main benefits of introducing CCs were related to the enhancement of soil quality and nutrient supply rather than to an increased yield of the following maize crop.

“…In particular, cover crops can increase the organic matter content of soil to enhance the soil fertility of agricultural land by helping to scavenge and retain nutrients, thereby making them available to subsequent crops; thus, cover cropping is a useful strategy for cropping systems. In addition, the introduction of cover crops can improve phosphorus (P) uptake by subsequent crops by maintaining an adequate arbuscular mycorrhizal fungi (AMF) spore density in the soil or by increasing AMF root colonization . Indeed, many previous studies have indicated that AMF benefit agricultural crops, such as maize ( Zea mays L.), soybean ( Glycine max ) and wheat, by increasing AMF root colonization and AMF hyphal density in the soil during early growth stages to enhance P uptake, as well as maize yield when the soil is P depleted .…”

AMF variables and maize performance were related directly or indirectly to maize grain yield, whereas root colonization had a positive effect on maize performance. AMF may be an essential factor that determines the success of cover crop rotational systems. Encouraging AMF associations can potentially benefit cover cropping systems. Therefore, it is imperative to consider AMF associations and crop phenology when making management decisions. © 2017 Society of Chemical Industry.

“…), and wheat (Triticum aestivum L.), in crop rotational system has been shown to maintain or increase AMF biomass, or P uptake and yield in subsequent crops [5] [6] [14]- [16].

“…Winter cover crops such as barley (Hordeum bulbosum L.), wheat, white clover (Trifolium repens L.) and other crops in rotation with summer crops have been used to enhance soil health and fertility [19] [20]. Arranging crop rotation with cover crops may maintain or increase P uptake and yield of subsequent crops [5] [6] [16]. However, Vandenkoornhuyse et al [21] [22] and Torrecillas et al [23] have mentioned that there is mounting evidence on host compatibility between host plant and some AMF species.…”

Introduction of cover crops may improve the diversity of arbuscular mycorrhizal fungi (AMF) in roots and soil under crop rotational systems; therefore, it is necessary to determine the potential for AMF communities to improve sustainable food production. We investigated the impact of cover crops, including wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), pea (Pisum sativum L.), and hairy vetch (Vicia villosa Roth.), on the AMF communities in their roots in autumn and spring sowing seasons with PCR-DGGE analysis. Although all four cover crops impacted the AMF community structure in roots, the diversity of AMF communities was unchanged among crop type or sowing season. Redundancy analysis (RDA) demonstrated that AMF communities within crop type were significantly different. However, the AMF community structures were not influenced by growing season, suggesting that growth stage in crops may be more responsive to shaping AMF community structure in crop roots than host crop identity.
