Phosphate Fixation
Farming trials have shown that when Phosphorous fertiliser is added to soil, more than half becomes fixed in the soil, leaving a much smaller amount for plant uptake.

Adding FCRD allows much more Phosphorous to be available for plant uptake, and thus can largely reduce amounts of Phosphorous fertiliser required. As a result use of fertilisers becomes more effective and efficient.

Reduced Sodicity
Excess weathering of the soils can lead to the breakdown of the soil structure. Sodium and Magnesium become lodged between the clay particles within the soil, which leads to sodicity, or soil erosion. Commonly, Gypsum is used to combat this problem. The calcium ions within the gypsum displace the sodium and magnesium while allowing the soil to keep its structure.

The calcium content within FCRD allows it to carry out the same role while also neutralising the pH, thus eliminating the need for Gypsum.

Reduced Acidity
Fishers Creek Rock Dust is effective at reducing the acidity in soil. It's micronutrients effectively increase the Ph (reduce acidity) in the soil. The chemistry behind this reaction describes how the Calcium and Magnesium elements enable the break in hydrogen bonds in the acidic molecule.

Traditionally, lime has been applied to reduce this acidity, however not only does lime only reduce acidity temporarily, but for every kilogram of lime used, 400g is emitted as carbon dioxide into the atmosphere.
