Potassium (K+) is one of the three main “pillars” of macronutrients essential for plant growth, alongside nitrogen and phosphorus. Because of this, it’s essential to provide adequate potassium to your plants – since it helps regulate yield size and quality. Let’s explore the role of K+ in more detail now.

Understanding the Roles Of Potassium

Potassium plays a crucial role in the relationships between plants and water. It forms weak complexes that provide the plant with readily exchangeable potassium.
When it’s plant-available, potassium helps directly promote the production of carbohydrates, promoting better plant health and higher Brix levels. However, it’s important to apply potassium at the proper frequency to enjoy these benefits.

In addition, potassium is an enzyme activator for many plant functions. When present in higher concentrations, it also encourages protein synthesis, which further helps facilitate the movement of potassium through plants.

Not all crops and soils have the same relationship with potassium. For example, crop types like grapes and citrus have high potassium removal demands. Stone fruits like peaches have lesser removal demands. You should calculate accordingly.

Potassium uptake can also be affected by oxygen level, aeration, soil moisture, soil temperature, region, and tillage systems, to name just a few factors.

Selecting Your Potassium Source

It’s important to consider the adulteration of your potassium source and limiting factors that may impair the optimum uptake potential of potassium. Traditional potassium sources like potassium chloride, potassium sulfate, potassium nitrate, and potassium hydroxide all have limiting factors to account for.

For example, potassium sulfate may not be a good option in soil where additional sulfur is not required. In contrast, a pure source of potassium like Pro K™ 0-0-20 from Ferticell may be a superior choice.

Try Pro K™ 0-0-20 And Improve Potassium Uptake In Your Plants

Pro K™ 0-0-20 is a great fertilizer and soil additive for soil that’s balanced yet lacking potassium. It includes little-to-no salt content, making it easier to design your potassium fertilizer programs without disrupting soil balance.
