Partners Networking to Advance South Island Dairying

Soil Nutrient Management Project

The project is focussed on the monitoring and scientific measurement of the changes which are occurring on the properties.  

It is driven by farmers, rural professionals and scientists who want to understand the implications of adopting the new fertiliser management strategies being actively promoted by agribusiness organisations and known as Biological Farming.   Many of these approaches are promoted on the basis of research which is not supported by traditional scientists, and there is interest from all parties in collecting information that can be more readily understood. 

The information over the three year provided will include:

• Environmental indicators (water use, soil condition, measures of available N, n leaching, pasture composition and soil biology, etc.)

• Production indicators presented in a form that allows direct comparison with benchmarking data from the Lincoln University dairy farm (LUDF) and SIDDC monitor farms;

• Economic indicators based on the Dairybase financial reporting.

The three year project life will allow the mapping of changes over time, and provide an independent evaluation of the differences and impacts of the two strategies.
