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.

Summary

  • Average pasture cover on Whakapono on the 16th August was 2060 kgDM/ha, which has slightly decreased to 1972 KgDM/ha. All the late calvers (300 cows – check) not including carry overs from both farms are grazing on Whakapono.
  • Waiora had a cover of 1884 KgDM/ha and has increased to 1920 kgDM/ha.
  • Growth rates have held and are at 24 on Whakapono and 27 on Waiora.
  • Baleage is being fed to Springers and late calvers. 1kg of PKE is being fed in shed to the milkers. Pit silage is just starting to be fed out to milkers on both sides.
  • Late calvers have come back to the milking platform. They spent one night on Waiora, then were moved over to Whakapono to even out the grazing that occurred on Waiora with the early calvers.
  • 19mm rainfall this week.
  • Milk production for Whakapono is at 1.53 KgMS/cow and for Waiora its 1.62 KgMS/cow.
