Potash

In 2012, world potash production, consumption and sales decreased from 2011. High inventories of potash, primarily in China and India, forced major producers to reduce output in 2012. U.S. production was estimated to have decreased to 900 kt (990,000 st) potassium oxide (K 2 O) in 2012 from 1 Mt (1.1 million st) K 2 O in 2011. World production was estimated to have decreased to 34 Mt (37 million st) K 2 O in 2012 from 36.4 Mt (40 million st) K 2 O in 2011. Canada continued to lead the world in potash production. Russia, Belarus and Germany were other leading producers, by order of output. The U.S. ranked eighth in world production.

Potash

In 2009, the world potash market deteriorated as world demand, trade and sales fell dramatically. After potash prices reached record high levels in 2008, many consumers and dealers delayed purchases until the price dropped. Potash prices did not recede as quickly as other fertilizer commodities, which led to further increases in potash stocks. In 2009, high stocks and lower demand contributed to a drop in world production of more than 30 percent from 2008. Nearly all major producers reported lower production in 2009, as many mines were idle in the first half of the year and world production was at 50 percent of capacity. Consumption of both fertilizers and industrial uses dropped significantly in 2009.

Peat

In 2005, peat was harvested in 15 US states. Florida, Michigan and Minnesota accounted for more than 80% of the US production. Reed-sedge was the dominant variety of peat harvested in the United States. More than 56% of all peat used in the US was imported from Canada. With the growing interest in gardening, landscaping related to home construction and golf courses, peat usage is expected to remain near current levels during the next several years.

Peat

Peat is a natural organic material of botanical origin and commercial significance. Peatlands are situated predominately in shallow wetland areas of the Northern Hemisphere. Commercial deposits are formed from the gradual decomposition of plant matter under anaerobic conditions over about a 5,000-year period.

Peat

The United States continued to be significant producer and consumer of peat for horticultural and industrial applications in 1999. Florida, Michigan and Minnesota were the largest producing states, in order of output.
