WALCO Western Agricultural Lime Co (Australia)

Lime WA Inc is also responsible as a group for the systematic testing and quality assurance of member's products including laboratory testing and the use of accredited calibrated scales on all loading devices. WALCO is currently diversifying its product offerings to include limestone rubble of various sizes and capstone rock, sourced from our Windy Harbour lime pit. We are also in the process of sourcing alternative soil conditioning products such as Gypsum and Dolomite.

The following are a few of the benefits you will gain by adding agricultural lime to acidic soils.

• Calcium is an important constituent of cell wall material, adding strength and stability to the plant. Calcium deficiency causes stunted growth
• Lime corrects acidification. Soil acidification is part of Australia's land degradation problem. As far back as 1989, the CSIRO estimated that soil acidification was costing Australia more than $300 million per year in reduced crop production

Most current testing of lime quality involves discovering the neutralising value of the lime based on method P33, which uses hydrochloric acid to react with the calcium carbonate neutralising the acid. The more acid that can be neutralised by a determined sample of the lime product the higher the calcium carbonate content of the lime. Fortunately your soil is nowhere near the acidity of hydrochloric acid. If it was then you would need a lot of lime in order to grow anything.
