1. Soil amendment products for banana crops
Grower Application - These products can be applied using grower equipment, which means
optimal timing and convenience. Application can be with worm or paddle drives, spreaders or
droppers.
Prescription Blends – Granule size and hardness allows blending with NPK fertiliser for a one
shot application. Nutrifert’s prescription blending services are available from depots in
Brisbane and Townsville. Alternatively, the products can be applied as a straight.
Find the right solution – As the table shows, these products address a range of issues.

2. Ultra fine particle size results in high reactivity of the pure calcium
carbonate. Therefore, greatly reduced rates are applied compared to
Aglime.
Appearance White round granule
Neutralising value 99%
Calcium content 39.2%
Particle size 95% less 45 micron (average 20)
Granulation sizing 2-4 mm
Common rates of application 10 – 20% of Aglime
Ultra fine particle size results in high reactivity of the pure calcium and
magnesium carbonate. Therefore, greatly reduced rates are applied
compared to Dolomite.
Appearance Off-white round granule
Neutralising value 99%
Calcium content 20%
Magnesium content 11%
Particle size 95% less 45 micron (average 20)
Granulation sizing 2-4 mm
Common rates of application 10 – 20% of Dolomite
Ultra fine particle size results in high reactivity of the pure gypsum.
Therefore, greatly reduced rates are applied compared to standard
agricultural Gypsum.
Appearance White round granule
Calcium content 22.4%
Particle size 95% less 45 micron (average 20)
Granulation sizing 2-4 mm
Common rates of application 10 – 20% of Gypsum
Banana crop production soils are typically depleted of soil organic matter due to intensive farming operations over a
number of seasons. Humisol supplies stable humates to improve soil organic matter. This product is available as a
granule for blending or a powder for fertigation.

The Importance of Neutralising
Value and Particle Size for Lime
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 and OzcalMag have 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.
Particle size comparison
Reactive neutralising zone
This means Ozcal an OzcalMag are 750%
more reactive than Aglime.
Even in its pure form, Gypsum has very
low solubility. The finer the Gypsum
particle the quicker calcium is released.
Ozgyp’s high purity and ultra fine
particles make it highly reactive
compared to agricultural Gypsum.
