Markets:  Agriculture



Our AgLime is certified with BioGro as an input for organics and is Fertmark certified to contain a minimum of 90% calcium carbonate. It is also processed to meet agronomic recommendations for particle size.

Fertmark certification: Minimum CaCO3 of 90%, 50% passing 500 microns and less than 5% retained on 2mm screen 

  • Agricultural lime is also known as ‘ground limestone’ and is produced by grinding limestone to less than 2mm.
  • Our agricultural lime is renowned for its consistency. We regularly test our AgLime via our in-house laboratories to ensure we are delivering the right grade.
  • AgLime is typically applied annually to maintain soil pH and soil health.
  • Not fit for aerial dispersal.

5 Key Benefits for AgLime

AgLime helps improve:

  • Pasture utilisation
  • Grow pasture
  • Fertiliser responses

Packaging Size:
Available in 25kg bags, 1 tonne sacks or in bulk.


  • 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...

    A low rate of lime on a steep hill country soil increases pasture and animal production. There is no response for 15 months, but thereafter lime increases ewe live weights by approximately 5kg/ewe, ewe fleece weight by 0.5-0.6 kg/ewe and lamb live weight at weaning by at least 6%...
