Potassium - getting the fruits and buds bigger!

Potassium is the 2nd most important element in plants:

It participates in managing the osmotic potential (hydro pressure) in the plant,

therefore brings up the plants resistance to drought,

monitors pH levels, activates enzymes, and more.

It has an important role in the plant resistance to dryness, as mentioned, and to pests and disease.

Absorbed by the plant as K+, a simple one this time..

This is also the way it's absorbed by the soil.

Most of K+ in the soil is part of the soil structure, about 90%.

A small part (~2%) is available for the plant in the soil solution.

And the rest of it is in the transfer section.

When we want to know how much K we have in the soil regarding plant growth,

we need to examine both quantity of K and availability of it.

Relatively to other elements, K is found in larger percentage in the fruit,

because of its role regulating osmotic potential: The plant actively transfers K to the fruit in order to get sugars and other compounds to the fruit using the osmotic potential and active cell gates.
