A technique using 15N‐labelled inorganic fertilizer was applied to estimate N2 fixation by
the forage legume Hedysarum coronarium L. and to ascertain the role of vesicular …

The ability of the external mycelium in arbuscular mycorrhiza for N uptake and transport was
studied. The contribution of the fungal symbiont to N acquisition by plants was studied …

The isotope 15N was used to estimate N2‐fixation by white clover, and N‐transfer from
clover to perennial ryegrass. Pure stands of each of these pasture plants and a mixed sward …

The significance of the external mycelium of arbuscular mycorrhiza for uptake and transport
of N from 15N‐labelled nitrate in benefiting plant nutrition, was evaluated under either well …

Summary The legume Medicago sativa (+ Rhizobium melilott) was grown under controlled
conditions to study the interactions between soluble P in soil (four levels), or a mycorrhizal …

Arbuscular mycorrhizal (AM) fungi take up nitrogen from the soil, translocate it and transfer it
to the host plant (Jennings, 1995; Smith & Read, 1997), often in significant quantities …

Background Arbuscular mycorrhizal fungi (AMF) form mutualistic symbioses with c. two-
thirds of all land plants. Traditionally, it was thought that they played no role in nitrogen (N) …

summary Three isolates of vesicular‐arbuscular (VA) mycorrhizal fungi, belonging to the
species Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe, G. fasciculatum (Taxter …

Mycorrhizal associations between some fungi and roots of the majority of higher plants can
increase the absorption of nitrogen from soil by increasing the specific absorption rate of the …

summary A pot experiment was conducted under glasshouse conditions to investigate the
effect of the inoculation of arbuscular mycorrhizal (AM) fungi on the growth and N uptake of …
