A resource with unique and beneficial properties
Our limesand resource at Boranup is unique to the area and indeed displays distinct characteristics from other lime sand resources. Known as "Neil's Pit", after the man who discovered and pegged the resource in the 1970's, it is rewarding to bring this high quality option to market after the painstaking process of ensuring mining extraction would be harmonious with the surrounding local and tourist activities.
- Ideally located to save growers in the SouthWest, Great Southern and Southern Wheatbelt seeking limesand from costly freight to Lancelin.
- Convenient backload after delivering grain to Bunbury or the many local agricultural operations that receipt bulk grain.
- Physical properties show excellent performance in typical online "Lime Calculators" such as those shown at http://www.soilquality.org.au/calculators/lime_comparison and recommended by WA Department of Agriculture
- RAV4 network access for AMMS accredited transport combination.
- Unique reactivity due to exceptional particle sizing and geomorphology, overcoming speed of reaction shortcomings typically seen in limesand.
- See opposite: Photo showing reactivity of the Boranup lime sand from Neil’s pit (RHS in both photo’s) compared to Lancelin lime sand. The yellow is solution pH 4 that turns blue at pH 7 to show the faster neutralizing effect. One gram of lime is added to the 200mls of solution (represents 1 T/Ha)

Working with Optima Agriculture has helped me learn much more about my soils. I have found their field days to be really worthwhile attending and their staff are knowledgeable...
We see CalSap as a tool that will help us get a liming effect in the sub-soil quicker...
We persevered until 2015 when we decided to try some CalSap and liquid Phosphate product from Optima last year...
After 10 years, I continue to use CalSap as the base of my soil sustainability program, which I use in conjunction with a nutrient management plan...
CalSap is easy to use as a monthly maintenance tool and easy to apply...
Since incorporating CalSap into our maintenance program we have noticed improved water penetration and a significant drop in sodium and salinity in our latest soil tests...
I would recommend CalSap Turf to anyone looking at options for sodium issues...
