"The overarching intent with any nutrient management effort is to get the right source of fertilizer at the right rate at the right time in the right place to optimize the crop's ability to grow and produce."

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.
