Nitrogen fixation of annual temperate clover species determined by the nitrogen difference method.

Abstract

The nitrogen fixation ability of Trifolium vesiculosum cv. Amclo and Trifolium subterraneum cv. Mount Barker in pure and mixed stands with Lolium multiflorum cv. Midmar were compared using the nitrogen difference method. The percentage and quantity of apparent legume-derived nitrogen, as affected by different nitrogen applications and grass seeding rates, was estimated. Illustrates with graphsLanguage: English
