Factors controlling legume nitrogen fixation and their measurement in the field

, : Factors controlling legume nitrogen fixation and their measurement in the field. Physiological Limitations and the Genetic Improvement of Symbiotic Nitrogen Fixation: 87-96

A flow through apparatus for measuring nitrogenase activity in field crops is described. A marked seasonal variation in nitrogenase activity in sainfoin was observed which was, in part, the result of the effect of defoliation. The acetylene based estimate of the nitrogen fixed annually by sainfoin was 146 kg ha-1 less than the nitrogen accumulated in the shoots.
