Project description
This project proposes to trial best-practice pasture renewal and management techniques with monitoring of the establishment, persistence and production of the key forage species. The information will be used to develop a value proposition that explicitly considers the costs, benefits, risks and uncertainties of pasture renewal in a farming system context. Together with consideration of the social context of technology adoption, this directly addresses the key constraints to higher rates of successful pasture renewal and adoption of new pasture technologies.
The issue/opportunity
Higher rates of successful pasture renewal and the wider adoption of new pasture technologies have the potential to deliver significantly more forage and so drive a major step forward in the profitability and sustainability of New Zealand's pastoral agriculture.
Industry has recognised this: the 2006 Dairy Industry Strategy aims to increase pasture harvested by 50% by 2015 and estimates that this will add about $6 billion in export value to New Zealand.
These technologies can also reduce the environmental consequences of grazing livestock.
For example, direct-drill sowing techniques enable better fertiliser and seed placement that require lower overall fertiliser application rates, which limits subsequent nutrient losses. In addition, reduced cultivation means that soil carbon losses are lower and there is less impact on soil structure and soil health. Better pasture establishment success rates and best-practice ongoing management results in pastures that are more persistent and more resilient with a greater potential to tolerate extreme climatic events such as drought.
The context/background
Pastoral industry bodies such as the Pasture Renewal Charitable Trust (a group representing more than a dozen pastoral industry companies) have identified a number of critical issues that currently limit industry growth: poor pasture condition, poor pasture persistence, low rates of pasture renewal with low success rates, and low rates of technology adoption.
Farmers themselves have identified a number of constraints to the adoption of new pasture technologies:
Lack of on-farm demonstration of successful pasture establishment and persistence in their region
Perceived high risk and uncertainty during pasture establishment
Distrust of information from commercial seed and fertiliser merchants, which is often based on inadequate short-term (1-2 year) trials. Much of this information can be contradictory and confusing
Lack of convincing value proposition for renewal of perennial pastures.
Methods
This project has a strong focus on on-farm case studies. Farmer initiated, there will be approx. 10 each in the Waikato and BOP. These trials will involve a number of pasture renewal options and will examine the entire pasture renewal process, from paddock selection to the persistence of the new pasture. The aim is to provide compelling demonstrations of a range of contrasting pasture establishment techniques. These may include cultivation options or different species/cultivars. Pasture performance and environmental quality will be closely monitored. Some of the monitoring will be done by farmers although the 'added-value' measurements of soil structure and pest status (for example) will be done by scientists.
In addition, some structured interviews will be conducted to examine the social context of the decision-making process in the adoption of pasture renewal technologies (multi-criteria decision making). This information will guide the development of the project outputs and help to maximise the capture of the opportunities outlined above: industry-wide improvements in profitability and sustainability.
Latest update
Ten farms (29 pastures) in the Waikato and ten farms (28 pastures) in the BOP are now being monitored and a broad range of pastures are covered. Eleven months of pasture measurement have now been recorded for most pastures.
Additional funding has recently been received from DairyNZ and the project has been extended to include endophyte testing (currently under way) and extension into the South Island (Canterbury and Otago), with pasture monitoring expected to start early 2010.
Publication of results has occurred in the Proceedings of the New Zealand Grassland Association and in farming media.

Update
Most of the farms have now been selected for this project-eight each in the Bay of Plenty and Waikato. A total of 48 paddocks now have cages installed and we have three months data. Three-fold differences in pasture production were measured between the "best" and "worst" paddocks on some farms. A survey of soil-borne insect pests revealed very high numbers of black beetle in many paddocks. These results have been discussed at three field days in the BOP and were also highlighted at the Waimate West Field Day in Taranaki.
Update
This project continues to be delayed by the contracting process. Apart from the core contract having only recently been signed, the co-funding contracts have required the development of quite lengthy documentation. This process is not yet complete. Despite these delays, some progress has been made on the selection of the farms: a field trip that visited five farms in the Bay of Plenty was held in September and a substantial amount of data collected on the pasture renovation process.
