Grolime agricultural lime improves the growth and nutrition of your grass, while boosting the performance of slurry and other fertilizers. When the ratio of water, air, minerals and organic matter in the soil is correct, Grolime also improves land drainage.

It is important to test the pH of soil, to ensure it does not have lime deficiency. Grolime agricultural lime should be spread every five years, ideally at a rate of 2 to 3 tonnes per acre in accordance with the results of the pH testing.

Grolime agricultural lime grading is as follows::

Neutralising Value: >95%
Passing 3.35mm Sieve: 100%
Passing 150 micron Sieve: 35%
Max Moisture Content: 3%


As a certified Grolime supplier, MC Group offer a one stop shop for your Grolime requirements from production to delivery to spreading lime should you require.

Our Grolime is available for delivery to customers in Cork, Kerry & West Limerick.


MC Group are committed to providing high quality agricultural lime to the farming community in Ireland.

Our lime is tested and approved by the Department of Agriculture who are the providers of licenses for the sale of agricultural lime.
