Our fertilisers are unique to the market.

Calcium Sulfate

Calcium Sulfate (gypsum) is combined with thCa™, an organic complexing agent. This makes the Calcium (Ca) in gypsum more readily available for soil and/or plant, without effecting or raising pH.

Calcitic limestone

Calcitic limestone combined with thCa™, an organic complexing agent. This converts insoluble calcium compounds to soluble and available calcium. Thsis results in greater delivery of calcium to the exchange sites on the soil colloid.

How does it work?

The soil colloid has degrees of affinity for various basic cations. This bonding increases with larger atomic weight, ion size and amount of charge. The percentage saturation for each of the cations will usually be within the following ranges for optimum performance.

The process of cationic exchange begins when water and basic cations (Ca, Mg, K, Na) meet the soil colloid. Based on the soil colloid’s degree of cation affinity, Calcium (Ca) will attach to the soil colloid releasing the smaller cations. The released cations (Mg++, Na+, K+, H+) are solubilized in the soil solution and made available to the plant or removed from the soil profile. As hydrogen is released from the soil colloid into the soil solution, acidity is reduced and pH is raised.
