Impact of the earthworm Aporrectodea trapezoides and the arbuscular mycorrhizal fungus Glomus intraradices on 15N uptake by maize from wheat straw

Impacts of earthworms on nitrogen acquisition from leaf litter by arbuscular mycorrhizal ash and ectomycorrhizal beech trees

“…For example, in grassland, 15 N uptake from grass litter by Plantago was not affected by EWs (Wurst et al, 2004). Similarly Eisenhauer et al (2009) found no difference in N uptake from Lolium perene litter in various herbaceous species in treatments with and without EWs, whereas EWs increased maize 15 N uptake from straw (Li et al, 2013). Our results support that EWs increase the mobilization of N from leaf litter and that both EMand AM-colonized tree seedlings profit to a similar extent from the additional N supply.…”

“…The interaction of EWs with mycorrhizal fungi likely affects plant nutrient acquisition (Milleret et al, 2009;Li et al, 2011;Li et al, 2013). However, in the literature, contrasting evidences are reported.…”

“…However, in the literature, contrasting evidences are reported. For example, in a field experiment, the amount of N mobilized from straw litter and taken up by maize plants increased in the presence of both EWs and AM fungi (Li et al, 2013), while in experiments using grass litter, the effect of EWs on plant N uptake in the presence or absence of AM was not significant (Wurst et al, 2004;Eisenhauer et al, 2009). The extent to which the impact of interaction between EWs and mycorrhizal fungi on N nutrition depends on habitat conditions, such as soil and litter quality (Milcu et al, 2008;Holdsworth et al, 2012) is unknown.…”

Interactions Between Arbuscular Mycorrhizal Fungi and Organic Material Substrates

“…In a follow up microcosm study under more controlled conditions, Li et al (2013) investigated the interaction between earthworms and AMF hyphae in the presence of 15 N-labeled wheat shoots (C-to-N ratio of 15.1:1) using a two compartment system. The second (hyphal only compartment) was inserted below the root compartment 30 d later to reduce the decomposition of the organic matter also added to this compartment while the maize seedling developed.…”

Rhizosphere interactions between earthworms (Eisenia fetida) and arbuscular mycorrhizal fungus (Funneliformis mosseae) promote utilization efficiency of phytate phosphorus in maize

“…AMF affects the growth and physiology of most plants because of AMF's extraradical mycelia, which increase the nutrient uptake capacity of roots by extending the amount of soil volume a plant can exploit (Tuffen et al, 2002;Li et al, 2013a). In the soil P cycle, AMF are considered to be P pumps that can improve the availability of soil P and increase the acquisition of P in different ecosystems and for different host plants (Eisenhaue et al, 2009;Wurst et al, 2004).…”
