The authors of this paper note in the conclusion: “Understanding plant growth, time to first graze and regrowth rates enables us to predict how many stock, of what class, will be required during the season. In the late 2000’s, working with a grower at Cumnock (Central West Slopes), we aimed to get 60 – 75 days grazing from the early sown cereals. This was usually achieved in two or three grazings but required good estimations of DM prior to and during grazing, and what growth rate could be expected during the ‘rest or recovery period’”.

The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.

Take home messages from the paper include:

  • Lime is the most effective ameliorant to increase soil pH
  • Organic materials are not as effective as lime in changing pH, but reduced exchangeable Al% significantly
  • Applying lime with organic materials could facilitate downward movement of alkalinity
  • However, over a longer term applying large amounts of organic materials could acidify soil due to nitrification.
