Ultra Fine granular Lime
- Ozcal can be applied by growers with standard fertiliser application equipment as a straight or blended with fertiliser.
- TheThe ultra-fine particles in every granule 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 adjustment and where calcium deficiency symptoms exist.
- Quick release upon contact with water for faster results that last.
The importance of neutralising value and particle size
Neutralising Value (NV) is an indicator of a Lime’s purity and its ability to neutralise acid in the soil. The most accurate way to assess lime is to use effective neutralising value (ENV), which is a calculation that takes into account the particle size and the NV of a lime. Agricultural Lime typically has an ENV of 40% to 80%. Ozcal has a NV of 99% indicating high purity and ultra fine particles. The smaller the particle size the more reactive the Lime is in the soil and the quicker acidity is neutralised.
Ultra fine granular Gypsum
- Ozgyp can be applied by growers with standard fertiliser application equipment as a straight or blended with fertiliser.
- The ultra fine particle size & high purity of Ozgyp results in better reactivity. Therefore, greatly reduced rates are applied compared to standard agricultural Gypsum.
- Ozgyp is a premium source of sulphur and calcium which is critical for plant growth. Also useful in the management of high magnesium and sodium in the root zone both of which cause hard soils.
- Quick release upon contact with water for fast results.
The importance of neutralising value and particle size
Gypsum deposits are generally considered to be of low solubility which makes ultra fine particles all the more important for effective uptake into the soil.
Ultra fine granular Dolomite
- OzcalMag can be applied by growers with standard fertiliser application equipment as a straight or blended with fertiliser.
- The ultra-fine particles in every granule 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 Dolomite’s purity and its ability to neutralise acid in the soil. The more accurate way to assess Dolomite is to use effective neutralising value (ENV), which is a calculation that takes into account the particle size and the NV of a lime. Dolomites typically have an ENV of 40% to 80%. Ozcalmag has a ENV of 99% indicating high purity and ultra fine particles.
The smaller the particle size the more reactive the Lime is in the soil and the quicker acidity is neutralised.
Ultra fine granular Gypsum and Zinc compound
- OzgypZinc contains 1% of Zinc Sulphate Monohydrate in every granule making it the ideal product for those soils with inadequate zinc levels.
- The ultra fine particle in every granule & high purity of OzgypZincTM results in better reactivity. Therefore, greatly reduced rates are applied compared to standard Agricultural Gypsum.
- OzgypZinc is a premium source of Sulphur, Calcium& Zinc which is critical for plant growth. Also useful in the management of high magnesium and sodium in the root zone both of which cause hard soils.
- Quick release upon contact with water for faster results.
The importance of neutralising value and particle size
Gypsum deposits are generally considered to be of low solubility which makes ultra fine particles all the more important for effective uptake into the soil.
Ultra fine granular Lime and Boron compound
- OzcalBoron contains 2% of Boric Acid in every granule making the ideal product for those soils with inadequate Boron levels.
- The ultra-fine particles in every granule of OzcalBoron results in high reactivity of the pure calcium carbonate. Therefore, greatly reduced rates are applied compared to Agricultural Lime.
- This product provides an efficient treatment for soil pH adjustment and where Calcium & Boron deficiency symptoms exist.
- Quick release upon contact with water for faster results.

Conditions of Sale
The goods are manufactured to specific standards and are sold in good faith, however no guarantee is given as the conditions and methods under which they are used are beyond the control of Advantage Agriculture. Before using, the user should determine the suitability of the product for its intended use.
Exposed Surface Area
Why are we able to use such low application rates compared to conventional bulk soil amendments?
It is simple mathematics. Advantage Agri products have a far greater number of particles for the same volume. Each time you halve the size of a particle you increase the number of particles by eight. The diagram below illustrates that if you halved a 1cm sphere six times you would end up 32,768 from that first 1cm piece.
