  • Dairy farmers rely on lime for maintaining intensive pastoral production and it has become an essential input for profitable dairying operations
  • Lime has played a vital role in the development and success of New Zealand’s dairy industry
  • Graymont continues to supply and support dairy farmers with high quality lime products and expertise, ultimately contributing towards increasing pasture palatability, farm productivity and profitability

By using our AgLime to get the soil condition right from the outset, there are many benefits that follow for the Dairy Industry:

  • Lime is completely natural, it therefore has no harmful effects on the environment
  • Because soil conditions are right, other fertiliser applications are much more effective
  • Good soil structure encourages grass and clover growth.
  • Lime encourages worm and bacterial activity which aerates the soil and improves drainage
  • Because soil structure and activity is right, decomposition is improved, nutrients are more readily available to plants, and of course, grazing improves
  • Lime improves root development which is essential for vigorous, healthy crops allowing plants to grow to their full potential
  • Using lime to lift pH makes adverse elements less available for plants:
    • Aluminum: If soil is below 5.5pH, the aluminum solubility locks up phosphate so it can't be used effectively by the soil
    • Manganese: More Manganese is evident when soil has a low pH. This will make pasture less palatable for the stock 

Effects of Aglime

Caution is Needed:

  • Farmers need to be aware of the risks of grazing dry cows in late pregnancy on recently limed pastures
  • Lime can have a negative effect on cows in the transition period leading to calcium deficiency (milk-fever)
  • Cows naturally defend themselves against milk-fever by mobilising calcium in their bodies
  • If pregnant dairy cows (springers) ingest calcium through lime particles still around on recently limed pastures pre-calving, the cow's metabolism tells it that it doesn't need to mobilise calcium as there is enough in its diet
  • When the cow does calve though, it is unable to mobilise sufficient calcium in its blood and may "fall over" with the condition hypocalcaemia or milk-fever

Products to use:

  • Nitrogen Needs Lime
    Applying nitrogen (N) fertiliser makes the soil more acidic. The change from ammonium or urea to nitrate leaves the hydrogen behind to acidify the soil. The amount of acidity depends on whether the applied N is leached as nitrate or taken up by plants and exported in produce...
