A web-based tool for comparing lime sources is available on soilquality.org.au
When applying lime it is important to be able quantify a number of issues other than the actual cost, and cartage and spreading costs. The quality of the product plays an important part in the pH neutralising capability of the lime. Lime can be sourced from many places, each having different characteristics, both within and between pits. It is necessary to know what the quality of lime being purchased and how effective is will be at neutralising pH.
This calculator discounts the neutralising value to account for the reduced effect of larger particle sizes which reduce the short term capacity of the lime to change the soil pH.
