Its Time to Lime
ITS TIME TO START ORGANISING YOUR AG LIME FOR NEXT SEASON
PACIFIC FERTILISER can assist with Soil Mapping, Ag Lime Supply & Spreading.
Often in the new year Ag Lime supply will get tight. It is better to get organised and get your soil tests or soil mapping completed before the end of the year to enable you to order the Ag lime in December or Early Janurary.
Using the latest Veris mapping trailer we can map your paddocks to provide a variable rate application map for our spreaders which vary the application rate of Ag Lime to match your soils varying pH levels.
The mapping trailer also collects data on EC, Organic matter and Topography building a valuble asset for you to build on in the future with NDVI and yield data etc.
Pacific Fertiliser can supply High Calcium Limestone products in bulk & bagged and in product variants from ultra fine powder through to granulated & prilled lime.
Ag Lime is a soil conditioner made from pulverised limestone (calcium carbonate). Its main use in agricultural and civil applications is to correct soil pH.
Ag Lime is generally used to increase soil pH, which can increase crop yields among a wide range of soil conditions. Ag Lime is often used to improve the physical structure of the soil by reducing surface crusting, increasing water retention, and reducing soil erosion. Lime treatment helps crops to better tolerate drought and/or wet conditions by increasing both root penetration and water percolation through the soil.

Problems with Wet Excavated Material
Construction site problems with wet excavated material
If you’re excavating moist material, and are lacking room, sun or more rain is forecasted, then lime could be the answer.
Lime comes in many forms with the most common forms being Ag lime, hydrated lime and quick lime.
- Ag lime is generally used to adjust soil pH in the agriculture and acid sulphate soils in civil applications. It is much cheaper and easier to handle but has very little drying capability
- Quick lime or hydrated lime, can dry up wet soil quickly, so that it can be compacted readily, forming a working table that will resist further absorption of moisture. Quicklime and hydrated lime are both highly effective in drying wet clay and silt soils. Major civil contractors have found that thus use of these lime products can expedite construction in wet conditions or wet weather, due to the drying action. Quick lime has somewhat greater drying capacity and dries more rapidly than hydrated lime.
Application of the lime for most soil drying applications is at around 3 to 5% lime addition (based on dry weight of soil), depending on soil moisture content and mixed into a to a depth of 150-250mm. Use of lime for drying wet soil has three simple steps: 1 Lime spreading/application, 2 Mixing lime and soil together; and Compaction.
Quick Lime and Hydrated lime are available in bulk pneumatic tankers, Bulkbags or pallets of 25kg bags.
Safety Note: Because quicklime can cause burns, and hydrated lime can irritate skin and eyes, precautions should be taken when handling these products. Workers who handle, spread, and mix the lime should wear the correct PPE including tight fitting goggles, gauntlet gloves, long sleeves, and pants tucked into boots. Wash off all lime dust from skin as soon as practical, but in case of contact with eyes flush out with clean water immediately and see a doctor. Protective cream is suggested for those with sensitive skin. Proper dust inhalation precautions should also be taken. Please ensure you read the relevant product Material Safety Data Sheet (MSDS) for more details before use.
- Quicklime and Hydrated Lime are safe to use and handle when appropriate precautions are exercised.
- Quicklime and Hydrated Lime are strongly alkaline (in excess of pH12).
- Quicklime (Calcium oxide) is potentially more hazardous to use than Hydrated Lime due to its strong exothermic reaction in the presence of water (>80°C)
- Hydrated Lime (Calcium Hydroxide) like most chemicals in common use is not dangerous to work with, providing a few simple precautions are exercised.
- Quicklime and Hydrated Lime are classifed as Hazardous according to criteria of national occupational Health & safety Commission, australia (noHsC).

Hot Lime
Hot Lime (or quick lime) for agricultural applications.
A mineral with chemical formula CaO, and is commonly called quick lime, burnt lime or hot lime. It is made by heating limestone (CaCO3) to drive off carbon dioxide.
Quick lime is used in preference to normal Ag lime or slaked lime for agriculture applications in some horticultural crops especially for treating clubroot. Hot lime is a faster-acting lime and has the highest neutralising value (NV) compared to other forms.
When hydrated with one mole of water, Hot lime forms slaked lime, Ca(OH)2. Hot lime generates heat when it becomes slaked with water and therefore speeds up the reaction to form calcium in the soil.
Quick Lime is more concentrated and caustic than agricultural lime and unpleasant and dangerous to handle, so couple this with a higher cost and its use is not commonly used in general agriculture such as broadacre and pastoral applications.
For reference Slaked lime (or hydrated lime) is calcium hydroxide Ca(OH)2 and has a higher neutralising value than agricultural lime but is more expensive and not usually used in broadacre and pastoral application.
Pacific fertiliser can supply quicklime, hydrated lime and normal ag lime in bulk. bulkbags and pallets of 25kg bags.
Types of Lime:
Agricultural lime (calcium carbonate)
Quick lime (calcium oxide) – also called caustic lime, hot lime, burnt lime and unslaked lime
Hydrated lime (calcium hydroxide) – also called slacked lime. Bulk seconds called Meadowlime
Dolomite – Pure dolomite is 54.3% CaCO3 and 45.7& MgCO3
Dolomitic Limestone or Magnesian limestone contains magnesium carbonate much lower ratios compared to dolomite eg the MgCO3 content may range approximately from 4.4-23%.
Magnesite (magnesium carbonate)
Burnt magnesite MgO (magnesium oxide)
Wet lime (their usefulness is determined by the NV and water content)
Granular Lime – granular limestone, prilled limestone or pelletised limestone
Lime and cement kiln dusts (their NV varies from 70–150 and Ca 25–54%. Mg is usually less than 1%)
FLUID LIME- liquid lime. This product is made by mixing very finely ground limestone (suspecnsion lime or ultra fine lime) with either water or liquid nitrogen fertilizer along with a suspending agent (attapulgite clay) and applying with a liquid fertiliser applicator.
SLAGS – Steel industry byproduct mainly is magnesium silicate or slag
FLUID-BED ASH- Byproduct of electrical utility companies from mixing limestone into ground coal in a fluidising bed. Also called stack dust.
Gypsum (calcium sulfate) – no or limited NV value
Limestone effectiveness – An expression of aglime effectiveness is based on the combined effect of chemical purity (CCE) and fineness. The ECCE is determined by multiplying CCE by factors like particle size (fineness.) Also referred to as effective neutralising value (ENV), total neutralising power (TNP), effective neutralising material (ENM) and, in the US “lime score”. -
New Central West Lime Product Released
Pacific Fertiliser releases a new Ag lime product for the Central & South West Regions in NSW.
The high analysis lime product specifically made for agricultural use. The sub 1mm sizing allows for better handling, increased spreading accuracy and minimal dust loss during application, without effecting solubility.
The general specifications of Pacific Fertiliser’s Ag Lime:
– Calcium Carbonate – CaCO3 – 96+%
– Total Calcium – Ca – 38+%
– Neutralising Value – NV – 98%The product is supplied & delivered in bulk tippers and we can offer the customer a spread price. For smaller customers we can offer bulkbags of powder or prilled lime.
Aglime is used in agriculture as a soil conditioner due to its superior neutralising value and a rich source of calcium. It is typically used to reduce soil acidity and improve plant growth by helping to increase the availability of essential plant nutrients in the ground.
