Boosting pulse crop performance on acidic soils locations
Aims

To examine boosting pulse crop performance on acidic soils.

Key messages

• Acidic soil layers below 5 cm adversely affect root growth and architecture, nodulation, plant vigour, N2
fixation and yield potential of acid-sensitive pulses.
• Moderately (pHCa 4.6–5.0) and severely (pHCa <4.5) acidic layers in the 5–20 cm soil profile are not detected using soil samples collected over standard profile depths of 0–10 cm and 10–20 cm.
• Finer sampling at 5 cm intervals is recommended to detect pH stratification.
• The current standard industry practice of spreading lime with no incorporation and sowing with knife point press wheels or disc seeders confines the lime effect to the surface layers.
• Careful paddock selection and forward planning is required to correct pH stratification in the topsoil (0–10 cm).
• Lime application and incorporation with a full cultivation operation at least 6–12 months before sowing acid-sensitive species could be necessary.
• Appropriate lime rates should be used to ensure pHCa >5.5 in the entire top 10 cm layer.
• The effect of pH stratification on more acid-tolerant species, including canola, lucerne and cereals, should also be monitored.

Acknowledgments

These surveys were part of the project ‘N fixing break-crops and pastures for high rainfall zone acid soils’, DAN00191, 2014–18, with joint investment by GRDC and NSW DPI and in collaboration with CSIRO Food and Agriculture, Holbrook Landcare Network and Mackillop Farm Management Group.
The contribution of the 21 growers participating in this project and their willingness to share their experience is greatly appreciated.
