​

Weld River Dolomite is a naturally occurring white crystalline rock which is crushed to a fine powder to produce a premium soil conditioning and pH neutralising agent.

Weld River Dolomite is a slow release source of the important plant growth elements, magnesium and calcium.

ABOUT

Dolomite is an economical way to increase soil pH in acidic soils, and to raise the magnesium levels in deficient soils. Dolomite also adds calcium and helps improve soil structure and increases the availability of some trace elements.

Weld River Dolomite is 100% natural premium grade dolomite mined in Tasmania.

PRODUCT SPECIFICATIONS

Chemical assay and sieve sizing specifications for Weld River Dolomite are based on average values from multiple representatives composite samples taken from run-of-mine stockpiles of crushed and screened sales product.

Sampling is done in accordance with standard Australian mining industry procedures and all assay sieve sizing tests are conducted by accredited commercial laboratories; ALS Pty Ltd in Brisbane and SWEP Pty Ltd in Keybrough, Victoria.

Analytical methods are also specified for the major and trace elements assayed.

CHEMICAL COMPOSITION

• Calcium carbonate 54.25%
• Magnesium carbonate content 40.6%
• pH (1:5 water) – 9.7
• Neutralising value (NV) 102.56%
• Effective neutralising value (ENV) 80.92% (This is the ultimate measure of lime quality - it takes into account the chemical composition (NV) and particle size distribution of lime). Online lime calculators are available for working out the value of competitor lime products in $/Ha.
