Abstract

Trial 89AL43, 90AL50, 90KO16

A preliminary survey using 14N:15N natural abundance to assess N2 fixation by pasture legumes in the field.

Location: Albany.

1. Develop a sampling methodology for the 1990 farm survey.
2. An initial assessment of nitrogen fixation by pasture legumes in the field.

Trial 90MT70

Using 14N:15N natural abundance to assess N2-fixation by subterranean clover.

Location Mount Barker Research Station

To examine symbiotic nitrogen fixation by subterranean clover, in detail, through one season in a productive pasture. To better assess the point in the season at which as one time sampling would most accurately determine the proportion of nitrogen fixed, integrated over the growing season for subclover.
