View Full ScreenALA Lime Calculator

The Lime Calculator allows users to calculate a recommended liming rate (t/ha) based on the cropping (enterprise type), measured soil pH, soil type and liming material to be applied.

The system uses ALA recommendations and was developed in partnership with The University of Hertfordshire; Agriculture and the Environment Research Unit (AERU).

Step 1: Select Farming Enterprise

Arable Grass

Step 2: Current Soil pH

Step 3: Soil Classification

The Liming Application Required
Calcium carbonate (ground limestone) required to achieve target pH in tonnes per hectare. Calcium carbonate in this calculator is based on a ground limestone with an NV of 54 and 40% passing through a 150 micron mesh, this is in accordance with the Fertiliser Regulations 1991.
