For decades Western Australian farmers have depended on lime sand applications to address soil pH imbalances. Traditional lime sand efficacy assessments have strongly considered calcium carbonate purity, neglecting crucial factors such as the speed of lime reaction and its ability to permeate the soil profile as they were developed in times of annual tillage practice.

In this video soil scientist, Burt Naude, presents a reactivity test developed by Optima Lime. This test shows how the physical and chemical properties of liming options can significantly influence the effectiveness of soil pH remediation. Selecting the appropriate lime application solution not only enhances performance but can also save time and money.

Optima Lime offers a range of lime sand and lime technology products specifically designed for Western Australian farmers. To learn how Optima Lime can help improve your soil, contact their product experts or staff soil scientists at
