Why Lime?

A pH of 6.2 is ideal for plant growth.

A pH of 6.2 unlocks your soils greatest potential for the widest range of pasture and crops needs. As a natural calcium carbonate, lime neutralises the acidity in soil, giving plants more access to key nutrients to reach their maximum potential.

There is a number of factors that degrade and impact a soils pH. This can include grazing practices, cropping, weather and acidic N-based fertilisers.

We are seeing anecdotal evidence of a widespread reduction in soil pH within Otago and Southland due to these factors that can often be overcome with a consistent lime application plan. 

Lime is also a natural and cost-effective soil conditioner, encouraging the presence of micro-organisms and earthworms.

Tailored fertiliser products for your farm

At AB Lime, we know that one size does not fit all.

Using a solid lime base we are able to develop customised blends specific to the needs of your soil and crops. 

We are able to achieve this by undertaking one of the most comprehensive soil analysis tests on the market. In addition to the standard nutrient status of your soil we are also able to undertake the following tests that help to determine how your specific soil will respond to fertiliser:

• Cation Exchange Capacity (CEC)

• Anion Storage Capacity

• Total Phosphate

• Total and Organic Sulphur; and

• Boron.

Know your nutrients

Soil is the major source of nutrients needed by plants for growth. The four main nutrients are nitrogen (N), Phosphorus (P), potassium (K), and sulphur (S).

Together they make up what is known as NPKS, other important nutrients are calcium, magnesium and trace elements. In nature, there are 17 nutrients necessary for plants to thrive and 14 of these come from the soil. See fact file 103 for more information.


Southland’s best quality AgLime

AB Lime is home to some of the region's highest quality calcium carbonate (CaCO3) rock - otherwise referred to as lime. We regularly test our lime at all levels within the quarry and are independently audited to ensure that our lime quality is consistent all year round. In addition:

  • We can customise the sizing of lime particles, so you can get both immediate release and slow release lime. 
  • Our kilns dry our lime to a moisture content of between 1.5-3%, so you are paying for lime and not water.
  • We are Fertmark registered and independently audited for quality assurance.
