The Precision Agriculture Association of NZ (PAANZ) is running this workshop to provide dairy and arable farmers information on ways to mitigate N leaching and improve efficiency and profitability, especially in Canterbury.

To be held on Friday 18th March at the Hotel Ashburton, the workshop programme starts at 10am as follows.

Introduction:
Workshop Chair: Mike Manning, PAANZ committee member

Welcome:
Craige Mackenzie, PAANZ Chair

• Andy Macfarlane: Where are we and what can we do with Canterbury
nitrate leaching limits.

• Profs Keith Cameron and Hong Di:
- What soils and what farming activities in are leaching hot spots and why.
- What can be done now about the Nitrate leaching hot spots
- The benefits of understanding your soils to reduce leaching

Programme
• Dr Carolyn Hedley with Prof Ian Yule
- The ability of EM and Variable rate irrigation to reduce N leaching
- Case study on risks, costs, benefits and providers as to what can be achieved in reducing nitrate leaching.

• Dr Tony Davoren
- The ability of soil moisture sensors, Irrigation scheduling and water metering to reduce N leaching
- Case study on costs benefits risks and providers.

• Dr Ants Roberts:
- Nitrogen Fertilisers
- Applying the right amount at the right time and what happens to N leaching when we get it wrong.

• Dr David Chapman
- Farm Systems
- What dairy farm systems can one adopt to materially reduce the nitrate leaching whilst maintaining or improving profitability.

LUNCH: 12pm - 1pm

SESSION: 1pm - 3pm
Attendees have time to engage with trade presenters (e.g. Agrioptics, Spreading Canterbury, variable rate irrigation companies, moisture sensing companies, nutrient budget providers etc. for two hours attendees could go and see these providers obtain a quote for installing or running that system on their farms.)

SESSION: 3pm - 4.15pm
• Prof Ian Yule
- Emerging PA Technologies in 1 to 3 years to reduce Nitrogen Leaching
- Emerging PA Technologies in 3 to 8 years to reduce Nitrogen Leaching

• Dr Paul Johnstone
- Flux meters in arable systems

Close & Thanks:
