  • OzcalMagTM can be applied by growers with standard fertiliser application equipment as a straight or blended with fertiliser.
  • The ultra-fine particle size of OzcalMag results in high reactivity of the pure calcium and magnesium carbonate. Therefore, greatly reduced rates are applied compared to Dolomite.
  • This product provides efficient treatment for soil pH problems and where calcium / magnesium requirements exist.
  • Quick release upon contact with water for fast results.

The importance of neutralising value and particle size

Neutralising Value (NV) is an indicator of a Lime’s effectiveness in the soil at neutralising acid. Aglimes have a NV of 50% to 90%. OzcalMag has a NV of 99% indicating high purity.

The smaller the particle size the more reactive the Lime is in the soil and the quicker acidity is neutralised.
