How Do Potassium Fertilizers Work?

Potassium fertilizers, like all chemical fertilizers, work by replacing lost nutrients in soil that are depleted of essential minerals from repeated harvesting activities. Commonly known as potash (element K), potassium was originally discovered by farmers centuries ago when they found that wood ash in metal pots was useful in aiding plant growth. Commercially produced potassium comes in two types, muriate of potash and sulphate of potash. Both are salts that make up part of the waters of the oceans and inland seas as well as inland saline deposits.


Potassium fertilizers are an easy way to replace potassium deficient soil with an essential nutrient for growth. What is the advantage of maintaining potassium in the soil? It helps plants maintain salt balance and aids in uptake of nutrients, promotes development of thick cell walls for improved winter hardiness and heat resistance, reduces damage due to drought and disease, aids in water uptake, influences enzyme performance and enhances overall health and vigor of plants.


Potassium is a soluble and highly leachable plant nutrient and it must be supplied at a constant rate. Once applied it is taken up by the plant rapidly. Although not necessarily harmful, over-application is of no added benefit to plants and therefore is an unnecessary added cost to the grower. Most plant experts discourage application of potassium to soil unless tests reflect it is needed.

What Are Fertilizer Boosters?

Because potassium is highly leachable, getting it to the plant’s roots and leaves more quickly is beneficial. Fertilizer boosters work to make the absorption process more efficient, therefore reducing the amount and cost of the added agent to the grower.

How BioWash Helps You

Field tests reflect that BioWash is especially effective at promoting absorption of fertilizers in plants because it actually increases the Cationic Exchange Capacity (CE) of plant root systems. This process increases plants’ ability to more efficiently absorb essential nutrients and water. By stimulating the electromagnetic exchange between the root and nutrient ions of the soil, Cationic Exchange increases the root size, allowing better absorption of nutrients to the plant. Field data reflects that Cationic Exchange in roots increases BRIX (sugar content) of plants, making them more resistant to cold and frost (down to 27 degrees). Because some insects find it difficult to efficiently digest plant sugar, use of BioWash reduces damage done by insects. Exceptional results at less cost to the grower. What a deal!
