Ferticell Pro K 0-0-20 is an organic-certified, fully soluble, plant-derived liquid fertilizer that is just as effective as it is good for the earth. This liquid formula is designed to supply plants with the essential potassium they need to optimize cellular function and normal growth mechanisms. When used in foliar application, Pro K has been shown to increase fruit yield and quality.
Since potassium is the third-most-essential element in crop growth, it’s important to have an organic source that can provide it while minimizing harm to the environment. With all organic ingredients, this fertilizer is the perfect tool to aid in your sustainable growing goals.
Ferticell understands plants on a cellular level, allowing you to grow the very best from the start. Whether you’re working on a vegetable garden, ornamental plants, or fruit trees, this fertilizer is adaptable and useful in a wide variety of circumstances. If you are dedicated to cultivating healthier plants and improving flower and fruit development, Ferticell Pro K 0-0-20 is the ideal solution.

Things To Remember About Potassium
Large applications of conventional potassium are needed if potassium levels are allowed to fall in the soil, often for years, before proper K levels are restored. Ferticell Pro K 0-0-20 is very effective, allowing considerably less material to be used compared to conventional potash sulfate or potassium thiosulfate applications. Ferticell Pro K 0-0-20 can minimize deficiencies that, when low levels are present, can cause significant damage to trees. Also, due to the reduced flowering of the surviving spurs, shoot and spur growth will be decreased. A number of our growers asked for a soluble, organic potassium fertilizer in 2015, which did not have the salt problems associated with a number of existing approved organic potassium fertilizers on the market. Their only choice for organic potassium fertilizer has been Sulfate of Potash (SOP) for many years. We applied for registration in 2016 and the first organic potassium extracted from plants was registered with WSDA & CDFA-OIM in 2017. Pro K is the only approved safe, plant-based, liquid potassium fertilizer with an organic potassium content of 20%. In order to be beneficial to plant activities, we have developed all the components of Pro K, giving it a lower salt index than mineral sources and is totally soluble.
Comparing Sulfate of Potash To Pro K
- For many years, Sulfate of Potash (SOP) has been our only option for organic Potassium until now.
- Some limiting factors of the SOP are solubility for a spray solution above 5% unless you purchase the powdered material, Pro K is a totally soluble, farmer-friendly liquid formulation.
- SOP has Sulfur up to 18% and may limit rates in several situations where Sulfur can add to anaerobic soil conditions Pro K is Sulphur free.
- Pro K is better managed as light and frequent applications as a sprayable bloom spray fertilizer Potassium easily leaching from sandy soils as a granular with rainfall.
- Coated K materials have a very light release rate, making it difficult to see immediate corrections in plants and/or fruit requiring high application rates. Pro K is very efficient often times seeing results in 24-48 hours.
Application Uses
Pro K can be applied in a myriad of application methods. It may be used indoors/outdoor with all hydroponic, NFT, drip, aeroponic, irrigation and continuous liquid feeding systems. It is also able to be foliar sprayed.
Media Uses
Pro K may be used with all soil and soilless media, including Coco Coir, and is compatible with all nutrient programs. Always check for pH and CF levels.
