Summary A technique is described for investigating the rooting pattern of species when intercropped, using Lithium as a non-radioactive tracer. The technique was tested on pure stands and mixtures of barley (Hordeum sativum) and field beans (Vicia faba), with 10% LiCl solution placed at depths of 0, 10, 25 and 62 cm. Pure stands of the two crops had similar patterns of Li uptake with depth. Growing the crops in mixture did not significantly change the pattern of Li uptake with depth, but did change total uptake. The Li uptake (m−2) by both species was reduced in mixtures, and was further reduced when the observed species was sown later than the other. The value of non-radioactive tracers, especially Li, in intercropping studies is discussed.
