"Perfect agriculture is the true foundation of all trade and industry - it is the foundation of the riches of nations. But a rational system of agriculture cannot be formed without the application of scientific principles, for such a system must be based on an exact acquaintance with the means of vegetable nutrition. This knowledge we must seek through chemistry."
-- Justus von Liebig, 1848 German chemist who discovered that nitrogen was an essential plant nutrient.

Important Potassium Fertilizer Products

Potassium compounds found in nature are actually the “salts” evaporated from sea water. Commerical forms of potassium are mined from deposits deep in the earth.

Most fertilizer products containing K, release the ion K+ to the soil for uptake by the plant. While K+ is not the only available form of K, it is probably the most important and widespread form. Except for sandy soil and soil containing a large proportion of organic material, K does not move much in the soil, meaning that placement of K in the root zone is essential.

Key Fertilizer Products

Sources of K for use on crops include animal manure, plant residues, and most importantly commercial fertilizer products. The most widely used commercial K fertilizer is potassium chloride (KCl), also known as muriate of potash (because the production process involves hydrochloric acid, also known as muriatic acid). Other widely used K products include potassium-magnesium sulfate, potassium sulfate, and potassium nitrate. A relatively small amount of potassium-sodium nitrate and various lime-potash mixtures are also applied. All these products release K+ ions in the presence of soil moisture, and potassium nitrate offers farmers a good source of N as well as K.
