Muriate of Potash MOP 0-0-60

Muriate of Potash 0-0-60 Specification

The declared analysis and supply detail are set out below. A Certificate of Analysis is issued on request against the batch you actually receive.

Nutrient Content of MOP 0-0-60

One tonne supplies 600 kg of potash (K₂O), equivalent to roughly 500 kg of elemental potassium. There is no nitrogen and no phosphorus — every kilogram of freight you pay is carrying potassium.

Nutrient supplied at different rates

Indicative conversion only. Set application rates against a current soil test and confirm them with a qualified agronomist.

Where MOP 0-0-60 Is Used

Potassium governs water use, sugar transport and stem strength. Deficiency shows up as lodging, poor grain fill and crops that suffer badly in a dry finish.

Broadacre cereals and oilseeds

Wheat, barley and canola tolerate chloride without difficulty, and for them MOP is simply the cheapest way to correct a potassium deficiency.

Pasture and hay

Hay removes an enormous amount of potassium — far more than grazing, because the whole plant leaves the paddock. Cut paddocks run down fast and need replacement potassium in a form that is affordable at the tonnages involved.

Sugarcane, rice, coconut and oil palm

Heavy potassium feeders that tolerate chloride, and in the case of coconut and oil palm actually benefit from it.

As the potassium base of a blend

MOP is the usual potassium component in broadacre NPK blends. Tell us the analysis your soil test calls for and we will blend to it.

The One Question That Decides MOP or SOP

Ask what the chloride will do to your crop.

Most field crops are indifferent to it. A specific group is not: potatoes, tobacco, grapes, citrus, berries, avocados and many vegetables lose quality and yield when chloride goes on, and for those crops the right product is potassium sulphate (SOP), even though it costs more per unit of potassium.

The second consideration is salt. Chloride adds to the salt load, so on saline soils or with salty irrigation water, MOP makes an existing problem worse.

Send us the soil test and the crop and we will tell you which one the numbers call for.

MOP 0-0-60 — Common Questions

Is muriate of potash the same as potassium chloride?

Yes. Muriate of potash, MOP, potassium chloride and KCl all mean the same product. “Muriate” is an old name for chloride.

How much potassium is in a tonne?

600 kg of potash as K₂O, which is about 500 kg of elemental potassium. At 100 kg per hectare you are applying 60 kg of K₂O per hectare.

Which crops should not get MOP?

Chloride-sensitive crops: potatoes, tobacco, grapes, citrus, berries, avocados and many vegetables. Use SOP on those instead.

Can MOP be used in fertigation?

Soluble grades exist for that purpose; standard granular grades are not intended for drip systems. Tell us the system it is going through and we will confirm the grade.

Does MOP acidify soil?

Very little. Its effect on soil pH is small compared with ammonium-based nitrogen fertilisers such as ammonium sulphate.

Packing and Quantities

MOP 0-0-60 is supplied in bulk, in 1,000 kg and 500 kg bulka bags, and in 50 kg and 25 kg bags. Minimum order is 10–25 MT, depending on the product and the destination. Packing formats, 20ft container loading figures, and bagging and marking are set out in full on our Delivery & Freight page.

Handling and Storage
