Potassium is essentially immiscible with all the alkaline-earth metals, as well as with zinc, aluminum, and cadmium. Potassium (as K +) is required by all plants and animals. Plants need it for photosynthesis, regulation of osmosis and growth, and enzyme activation. Every animal has a closely maintained potassium level and a relatively fixed potassium-sodium ratio.


The largest soil component of potassium, 90 to 98%, is the soil minerals such as feldspar and mica. Very little of this potassium source is available for plant use. The second soil potassium source is the non exchangeable potassium, 1 to 10%, and is associated with the 2: 1 clay minerals.

A podium for potassium

Jan 21, 2009Most potassium cannot be used by plants as is. When the minerals weather, some potassium ions bind to clay particles in the soil. Eventually the clay weathers, releasing potassium, which can then form a simple bond to negatively-charged soil particles. This allows potassium to be released into soil solution,

What is the Role of Phosphorus (P) and Potassium (K) in

The original sources of potassium are the primary minerals, such as micas and potassium feldspar. As these minerals weather, the potassium becomes more available as readily exchangeable and soluble potassium which can be adsorbed by plants roots. At any one time, most soil potassium is, in primary minerals and nonexchangeable forms.

In addition, Peristerite is the name given to feldspar containing approximately equal amounts of intergrown alkali feldspar and plagioclase . Barium feldspars. Barium feldspars are also considered alkali feldspars. Barium feldspars form as the result of the substitution of barium for potassium in the mineral structure.

Why Your Cannabis Plant Needs Potassium

May 15, 2016Like nitrogen and phosphorous, potassium is considered "mobile" in plants and can be scavenged from lower older leaves up to newer growth high in the canopy in times of scarcity. It is difficult at first glance to differentiate potassium deficiency in Cannabis from a lack of nitrogen or phosphorus,

How to Reduce Potassium Levels in Soil

A bit too much potassium in garden soil is not typically a problem for most plants, but in high excess, potassium can cause problems. One major problem is the inhibition of calcium. Common causes of exorbitant potassium levels include over-fertilizing and a large number of rocks and minerals in the soil.
