“…In the intercropping of legumes with nonlegumes, N fixed by legumes becomes available to nonfixing companion species (Carranca, Torres, & Madeira, ; Moyer‐Henry, Burton, Israel, & Rufty, ). Previous intercrop study demonstrated that 32%–58% of the N assimilated by sorghum was derived from soybean (Chu, Shen, Li, Zhang, & Wang, ; Fujiu et al., ), and these N transfers appeared mostly in different communities between N 2 ‐fixing and non‐N 2 fixing plants (Hamel, Barrantes‐Cartin, Furlan, & Smith,; Chu et al., ; Haby, Stout, Hons, & Leonard, ; Isaac et al., ). Inoculating with arbuscular mycorrhizal fungi (AMF) and rhizobium could improve the N fixation efficiency of legumes and enhance the transfer of N to companion graminaceous crops (Fustec, Fabien, Stéphanie, & Jean‐Bernard, ).…”

Nitrogen (N) deficiency occurs in over 80% of karst soil of southwest China, which restricts regional agricultural production. To test whether N fixed by legumes becomes available to nonfixing companion species, N fluxes between soybean and maize under no, partial, and total restriction of root contact were measured on a karst site in southwest China. N content and its transfer between soybean and maize intercrops were explored in a 2‐year plot experiment, with N movement between crops monitored using 15N isotopes. Mesh barrier (30 μm) and no restrictions barrier root separation increased N uptake of maize by 1.28%–3.45% and 3.2%–3.45%, respectively. N uptake by soybean with no restrictions root separation was 1.23 and 1.56 times higher than that by mesh and solid barriers, respectively. In the unrestricted root condition, N transfer from soybean to maize in no restrictions barrier was 2.34–3.02 mg higher than that of mesh barrier. Therefore, it was implied that soybean/maize intercropping could improve N uptake and transfer efficiently in the karst region of southwest China.

“…Indeed evidence suggesting direct N transfer from legumes to cereals grown under mixed cropping systems has increased considerably (Patra et al 1986;Fujita et al 1990;Martin et al 1991). However information on the effect of temperature on the release of nitrogenous compounds by legume root systems is scanty.…”

“…Due to differences in architecture of root system, physiology and growth cycle, these species in mixtures use greater quantity of a resource and utilize it more efficiently than if they are grown alone (Hauggar-Nielsen et al 2001). It is often assumed that a portion of the N 2 fixed by an intercropped legume is made available to the associated non-legume (Fujita et al 1990).…”

The effect of mineral nitrogen (N) nutrition on seed production and acquisition of 15 N from fertilizers by components of cereal-pea mixtures was investigated. Yields of wheat-pea and oats-pea mixtures raised together with the increase of cereals percentage in the pot, and higher seed yields of mixture with barley was affected by a larger share of pea plants. The percentage of nitrogen derived from fertilizers was significantly higher in cereals as compared with pea. Pea accumulated the greatest quantity of nitrogen from fertilizers in straw and roots, and cereals translocated 15 N mainly to ears -grain and glumes with rachis. The percentage of 15 N in seeds of pea amounted to 15% on the average, and in grain of cereals -54% to 60% of the total N taken up.
