What’s the Distinction In Between SOP and MOP? (Upgraded 2024)


The world’s population continues to grow, therefore too does require for farming crops. Not remarkably, it’s ending up being significantly essential for farmers to grow more crops more effectively.

That’s where potash fertilizers been available in– they not just increase food quality, however likewise increase crop yield. Farmers usage different fertilizers to grow crops, however the 2 most typical are sulfate of potash (SOP) and muriate of potash (MOP).

Canada is the world’s leading potash nation without a doubt, with yearly output topping 16 million metric heaps (MT) in 2022. China took the 2nd area in regards to overall potash production at 6 million MT, followed by Russia in 3rd location at 5 million MT.


Financiers thinking about the worldwide potash fertilizer market must understand the distinction in between SOP and MOP. Continue reading for a take a look at their typical usages, in addition to production approaches and which business are are mining these products.

Potash fertilizers: What is muriate of potash?

It can be helpful for soil that is low in chloride, assisting to construct resistance to illness in plants.

There are some disadvantages to this type of potash fertilizer. For instance, if high levels of chloride exist in the soil or if watering water is being utilized to grow crops, including MOP can develop a hazardous imbalance in plant nutrients. That implies levels of the fertilizer need to be thoroughly handled, and MOP needs to just be utilized for choose crops.

Still, MOP stays among the most business fertilizers in the potash household, with over 34.6 million MT consumed in 2021 compared to simply 1.8 million MT of SOP. The outlook for the potash fertilizer market as a whole stays favorable, although in 2023 MOP rates fell from the highs they experienced in March 2022– those levels eventually ended up being cost-prohibitive for farmers. While rates are anticipated to stay soft in 2024, need for potassium chloride is set to grow at a compound yearly development rate of 4.13 percent in between 2023 and 2030.

Nutrien (TSX: NTR, NYSE: NTR), a business formed by the merger of Potash Corporation of Saskatchewan and Agrium, is a significant manufacturer of MOP. Nevertheless, due to expected future need for fertilizers that promote crop production and plant development, lots of smaller sized business have actually started checking out and establishing their own potash tasks.

For instance, Highfield Resources (ASX: HFR) is an MOP explorer working to bring its Spain-based Muga potash job into production. Muga is anticipated to produce more than 1 million MT of MOP each year, with EBITDA pertaining to around 410 million euros every year once it reaches complete production. Muga is prepared for to get in building and construction in early 2024.

Saskatchewan-based Western Potash, a subsidiary of Western Resources (TSX: WRX), started hot mining in mid-2020 as part of Stage 1 mine building and construction at its Turning point MOP job. Commissioning of the processing plant began in Might 2023, with plant production slated to start in December.

Gensource Potash (TSXV: GSP), which is likewise based in Saskatchewan and concentrated on MOP, revealed in early 2020 that farming chemical business HELM would be the offtaker for the business’s Tugaske job in the province.

Utilizing SOP enhances both quality and crop yields and makes plants more durable to dry spell, frost, bugs and even illness. SOP can enhance the appearance and taste of foods and increase a plant’s capability to soak up essential nutrients like phosphorus and iron.

Frequently, SOP is utilized on high-value crops like fruits, veggies, nuts, tea, coffee and tobacco. It works much better on crops that are delicate to chloride, which can be harmful to some vegetables and fruit plants.

SOP is not a naturally taking place mineral, and normally need to be produced through chemical approaches. Since of the resource-intensive procedures utilized to develop it, SOP is priced greater than MOP. The most typical approach utilized to produce the fertilizer SOP is called the Mannheim procedure. It includes putting potassium and other raw minerals into a muffle heating system that is warmed above 600 degrees Celsius, developing a response in between potassium chloride and sulfuric acid. Fertilizer produced like this represent approximately 50 to 60 percent of worldwide SOP supply.

The 2nd most typical method of making SOP, representing about 25 to 30 percent of supply, is by responding potassium chloride with different sulfate salts to form what is called a double salt.

” The most typical basic material utilized for this function is salt sulfate. Salt sulfate, either in the kind of mirabilite (likewise called Glauber’s Salt) or sulfate salt water, is treated with salt water filled with MOP to produce glaserite,” Kalium Lakes (ASX: KLL, OTC Pink: KLLKF), a Western Australia-focused SOP business, discusses on its site “The glaserite is separated and treated with fresh MOP salt water, disintegrating into potassium sulfate and salt chloride.”

There are likewise operations that produce this kind of potash fertilizer by utilizing salt mixes from natural salt water. This needs salt water with high sulfate levels that are usually discovered in salt lakes. Business able to utilize naturally taking place salt water consist of Compass Minerals International (NYSE: CMP), which runs out of Overland Park in Kansas, and Chile’s SQM (NYSE: SQM), which has operations in the Salar de Atacama.
