The use of sulpHur in reducing the alkalinity of soils is well documented. Australia has no sulpHur mines and the importation of elemental sulpHur is too expensive to apply to soils in sufficient quantities to achieve an economic result.

Refined SulpHurcan take a very long time to work in the soil . CKS., on the other hand, is in an active oxidizing state, so it goes to work immediately.
CKS. is a naturally occurring soil acidifier- 14-20 % ELEMENTAL SULpHURMined and crushed product . Ai. May vary.
Typical Analysis of CKS.
Potassium K % 5
SulpHur(elemental ) % 16
SulpHurSO4 % 20
Calcium % 28
One single application cannot solve all growing needs in permanent crops. Annual applications may be necessary, and as pH comes down, application rates can be reduced. You will not be able to solve a pH problem in one single application in one year. pH reduction should be slow and steady, and is often off-set by the pH of applied water during the year.
Aluminium in the form of the Potassium Aluminium SulpHate. Aluminium SulpHatein itself is a soil acidifier. Aluminium is the third highest element found in the earth's soil (8% to 14%). Aluminium does not become available to plants until the soil pH < 5.
Micro-nutrientsCKS contains Zinc, Iron Manganese, Copper, Boron and Molybdenum. Nickel is also present in small amounts and considered the seventeenth essential element. Iron is the most abundant mineral with 1 to 2% as Iron SulpHate. The above nutrients are either in a sulpHateform and/or in a silicate form. Sodium levels are very low at + or - .06%.
CKS. is a natural source of Potassium (5 % ), a valuable high-use plant food.
CKS. contains Gypsum in a natural soluble state providing both soluble
calcium and exchangeable Calcium to the soil which will enhance water.
penetration and increase cell-wall strength.
pH reduction starts as soon as water is applied to the soil. The speed and level
of reduction is determined by the application rate and frequency of application.
The reduction can be controlled by the need to amend a particular soil to suit the crop being grown.
If you are farming on alkaline soils, CKS.FERTILIZERS may be able to help you increase the percentage of plant availability of applied fertilizer.
By reducing soil pH with CKS, BSES soil P is made available to the plant.

On alkaline soils P gets tied up as Ca pHospHates which can be solubilised by acid. Soil testing will indicate the presence of Ca pHospHates. If Colwell P (sodium bicarbonate extractable) and BSES P (acid extractable P - this extractant hops into Ca pHospHates) are similar there would be little to be gained from applying elemental S. When acid P is much higher than Colwell P, then Psorption will be high and there would be benefit in using elemental S.
hope this helps
What is CKS.?A naturally occurring mined product, 100% natural containing the following elements: Elemental sulpHur,
SulpHates, ThiosulpHates, Potassium, Calcium, Iron, Magnesium, Manganese, Copper, Zinc, Boron, Molybdenum, and Selenium.
What is its use?CKS. is a natural soil acidifier. 16% elemental sulpHur.
pH reduction starts as soon as CKS. is applied to the soil and irrigated or incorporated.
Where is it used?CKS. can be used where high pH soils are contributing to nutrient tie up, hard setting soils that lack water holding capacity and good water filtration.On all soils where plants struggle to reach their potential due to high alkalinity.
Application RatesDetermined by soil test. Recent soil tests can be submitted to CKS. FERTILIZERS.
A detailed report will follow any submitted request for information outlining appropriate rates , and the timing of applications
ApplicationCKS. may be applied with a conventional spreader for broadacre application.
A suspendable formulation is available for application to tree and vine crops through sprinkler or drip irrigation.
