KA: the most soluble form of potassium
There are many ways to manufacture liquid fertilizer products and arrive at a desired analysis. If two products have the same analysis with different source products, they are not the same and should not be expected to perform the same. For example, two different foliar products may both have 10% potassium but one is derived from potassium borate with a solubility of 15.8 g/100 ml. The other product also has 10% potassium but is derived from potassium hydroxide with a solubility of 121 g/100 ml. In this scenario, the potassium hydroxide containing the product’s potassium is nearly 8 times more soluble or plant available!
What about absorption through plant leaves?
Potassium acetate has 40% faster absorption than other K carriers!
This can be yield consequential! The faster a product is absorbed into the plant, the less is lost from evaporation. Only ingredients that enter the plant can influence yield.
