- OzcalTM can be applied by growers with standard fertiliser application equipment as a straight or blended with fertiliser.
- The ultra-fine particle size of Ozcal results in high reactivity of the pure calcium carbonate. Therefore, greatly reduced rates are applied compared to Aglime.
- Lower application rates allow growers to carry out annual soil maintenance combined with their fertiliser applications, rather than large singe doses of Aglime every 3-5 years.
- This product provides an efficient treatment for soil pH problems where calcium deficiency symptoms 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%. Ozcal 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.
