The potash price has been on the decline since 2013′s cartel breakup between Russia and Belarus, but the amount of potash on the world market is expected to increase over the next few years. Specifically, the US Geological Survey (USGS) sees global potash production capacity reaching 61 million tonnes by 2018, up from the current 55 million tonnes. Luckily for potash producers, demand for the fertilizer is poised to increase as well, though it is unlikely to keep pace with the world's rising production capacity. In 2015 the world consumed 36 million tonnes of potash, and that number should grow to 38 million tonnes over the next three years. With those figures in mind, it's interesting to take a look at which countries produced the most potash in 2014. Here's an overview of the 10 top potash-producing countries that year, as per figures from the USGS. 1. CanadaMine production: 9.8 million tonnes Despite a decline in production between 2013 and 2014, Canada remains the world's top potash producer. Furthermore, the USGS believes that new mine development and the expansion of several existing mines in the country should solidify Canada's position at the top of the potash heap in years to come. The country is home to the world's largest fertilizer company by capacity, PotashCorp (TSX: POT), which operates six Canadian potash mines. In response to falling potash prices, the company announced layoffs that affected 18 percent of its workforce at the end of 2013. Further changes to the company's workforce are possible in the future as it tries to adjust to the current potash market. 2. RussiaMine production: 6.2 million tonnes Russia boosted its potash production by 100,000 tonnes in 2014, and is home to some of the world's largest known potash reserves. Recently, Industrial Minerals reported that Industrial and Commercial Bank of China and China Construction Bank engaged in a loan deal worth over $500 million with Russian potash company Uralkali (OTCMKTS:URAYY). This move gave China greater control over global potash production, as Uralkali is responsible for 20 percent of the world's potash output. 3. ChinaMine production: 4.4 million tonnes China has an immense need for potash, and the country produces a significant amount of the substance at home. Demand far outstrips supply, however, and the country remains a net importer of potash. That gives the Asian nation incredible control over the market value of potash. Traditionally, Chinese potash buyers make deals with global suppliers in February of each year. These agreements set the tone for the potash price throughout the year. This year, Bloomberg reported deals were slow to materialize.
