NZARM Annual Conference 2002

Soil Quality and Sustainable Land Management

April 3-5, 2002, Massey University, Palmerston North

The Soil Quality and Sustainable Land Management Conference is being held between April 3-5, 2002, at Massey University, in Palmerston North. This conference is being organised by programme leaders of two public good research programmes (Peter Stephens (Landcare Research) and Prue Williams (Crop and Food)) in association with the New Zealand Association of Resource Management (Bill Bayfield).

The conference will consist of two days of presentations with ample time for discussions. Oral presentations and posters will focus on soil quality research and its practical applications. Conference sessions will focus on soil quality indicators, soil assessment tools, uptake of research for policy and management, sustainable land management techniques, environmental monitoring systems, and use of the Internet as a communication medium and information source. There is also a field trip (covering crop land and hill country issues). A conference proceedings of extended abstracts will be published.

  • 10:00 –11:30 am Ballantrae AgResearch Hill Country Research Station
    Interaction between agriculture and the environment. 

The programme will include a visit to the long-term fertiliser and grazing farmlets (established in 1972) to discuss the long-term impact of intensive pastoral agriculture on the chemical, physical and biological properties of hill soils. If time permits and there is sufficient interest, brief updates on the other soils related research in progress will be given. This work covers the stock treading on soils (and includes the new tools), the tree pasture study, and the soil fertility challenges facing low-chemical and organic producers. The farmlets cover 40 ha so people will be required to walk some distance (1 to 2 km).

Hosts – Alec Mackay and Gregg Lambert (AgResearch)

  • 11:30 am –1:00 noon. Travel from Ballantrae to the Ashhurst  Domain pavilion for a BBQ lunch and view the wind farm from the observation centre.
  • 1:00 – 2:15 pm. Soil quality, environmental and land management issues under no-till and conventional tillage. (NZ No-Tillage Association focus farm in the Manawatu)
    Hosts– Craig Ross (Landcare Research), David Horne (Massey University), Glyn Francis and Mike Beare (Crop & Food Research)
  • 2:15 – 3:15 pm. Soil quality, environmental and land management issues under long-term conventional tillage, and recovery rates under pasture.
    Host – Graham Shepherd (Landcare Research)
  • 3:15 – 3:30 pm. Afternoon tea and conclusion of conference
  • 3:30 Return to Massey University and Airport.
