The need for lime in soil and composts has long been established. Lime has two main functions:

* Reducing acidity

* Supplying calcium either alone or with magnesium.

Field tests using soil indicators are useful for identifying acidity.

Lime recommendations are intended to raise the pH from the surface to 15 cm of soil. Where cultivations are deeper or

acidity occurs below 15 cm the quantity of lime should be increased proportionately. Lime should be applied well before sowing or planting out because it takes some months for acidity to be corrected completely.

Limestone Dust: Limestone dust is courser than ground lime and is used more for Grass land were it can be left to slowly correct the pH balance over time.

Ground lime: Ground lime is finer than Limestone dust and is used where crops are failing or can be mixed in with the crop when planting this will help the crop grow better and still change the pH balance.
