Other methods include dissolution mining and evaporation methods from brines.

How did potash become a major industry in the 18th century?

In the late 18th and early 19th centuries, potash production provided settlers in North America a way to obtain badly needed cash and credit as they cleared wooded land for crops. To make full use of their land, settlers needed to dispose of excess wood. The easiest way to accomplish this was to burn any wood not needed for fuel or construction. Ashes from hardwood trees could then be used to make lye, which could either be used to make soap or boiled down to produce valuable potash. Hardwood could generate ashes at the rate of 60 to 100 bushels per acre (500 to 900 m³/km 2 ). In 1790, ashes could be sold for $3.25 to $6.25 per acre ($800 to $1,500/km 2) in rural New York State – nearly the same rate as hiring a laborer to clear the same area. Potash making became a major industry in British North America. Great Britain was always the most important market. The American potash industry followed the woodsman's ax across the country. After about 1820, New York replaced New England as the most important source; by 1840 the center was in Ohio. Potash production was always a by-product industry, following from the need to clear land for agriculture.

What is the name of the compound that is made of potassium?

Potash refers to potassium compounds and potassium-bearing materials, most commonly potassium carbonate. The word "potash" originates from the Middle Dutch " potaschen ", denoting "pot ashes" in 1477. The old method of making potassium carbonate ( K#N#2CO#N#3) was by collecting or producing wood ash (the occupation of ash burners ), leaching the ashes, and then evaporating the resulting solution in large iron pots, which left a white residue denominated "pot ash". Approximately 10% by weight of common wood ash can be recovered as potash. Later, "potash" became widely applied to naturally occurring potassium salts and the commercial product derived from them, although it most probably derived its name (where it was used) from the anion of the acid that replaced the carbonate moiety, a common equivocative use of "potash" for "potassium".

Why is potassium important for plants?

Elemental potassium does not occur in nature because it reacts violently with water. As part of various compounds, potassium makes up about 2.6% of the Earth's crust by mass and is the seventh most abundant element, similar in abundance to sodium at approximately 1.8% of the crust. Potash is important for agriculture because it improves water retention, yield, nutrient value, taste, color, texture and disease resistance of food crops. It has wide application to fruit and vegetables, rice, wheat and other grains, sugar, corn, soybeans, palm oil and cotton, all of which benefit from the nutrient's quality-enhancing properties.

How much potassium is removed from crops?

High yielding crops remove large amounts of potassium in the harvested portion of the crop. For example, harvesting 9 ton alfalfa/A will remove over 450 lb K2O. Similarly, a potato yield of 450 cwt/A removes 500 lb K2O, and harvesting 40 ton/A of tomatoes will take off over 450 lb K2O/A. But these high rates of nutrient removal are not usually being matched with fertilization. For example, In Idaho an average of four pounds of potash are removed in crops for every pound that is added back. In the Pacific coast states, over two pounds of potash are removed on average for every pound returned to the field as fertilizer. It’s little wonder that K deficiency is becoming a more common occurrence in agricultural fields.

Why is potassium removed from the soil?
