What is agricultural lime?

An agricultural liming material is defined as a material whose Calcium and Magnesium compounds are capable of neutralising soil acidity. These materials include limestone and chalk, quicklime, hydrated lime, marl, shells and by-products such as slag.

What must I consider when purchasing agricultural lime?

The following factors should be considered:

  • Soil Analysis (pH, soil structure etc.)
  • Target pH
  • Liming material to be used (Neutralising Value, sizing, composition)
  • Cost comparison
  • Legal requirements (Fertiliser Regulations)

How and when do I test my soil pH?

Monitoring of soil pH should be a key part of the annual farm Soil Management Plan.

Testing and recording can be easily undertaken using proprietary soil indicator solution, pH probe meters and laboratory pH meters. The ALA recommends that this is undertaken professionally. Account should be taken of individual soil types within a field as composite samples make no allowance for variations in pH.

What is Granular Lime?

Granular Lime is an agglomeration of very finely ground particles of Calcium or Magnesium Carbonate formed into granules. In this form it can be applied by growers at a time of their choice. It should be considered as a rapid maintenance application to the top few centimetres of soil rather than a remedial treatment for the whole soil profile.
