Abstract
Maximum nitrogen fixation (N2 fixation) will only occur if conditions favour rapid development of functional nodules and vigorous plant growth.
Soil pH was the primary factor limiting the yield and nitrogen (N) contribution of acid-sensitive pulse crops in 83% of commercial paddocks surveyed in central and southern New South Wales (NSW), Victoria (Vic) and South Australia (SA).
Once low soil pH is ameliorated, fine-tuning of agronomic management that accounts for sowing time, soil type, herbicide usage, nutrition and disease pressure will maximise the opportunity for legumes to fix N.
Forward planning, effective nodulation and early plant vigour set the production and N2 fixation potential of pulse crops
