Protassium+

A Comparison of Potassium

When choosing a potassium source for almond fertilization, it pays to take a closer look at what you’re actually getting for your money and what you're not getting. Some of the factors you’ll want to consider include: K content, value-added nutrients, risks in over-application, application costs, yield performance, and overall quality. With Protassium+, your plants benefit from high K, sulfate sulfur, and a significant absence of chloride and salt.

Know Your K

Compare Costs Correctly

Dry Protassium+ (SOP) is a cost-effective alternative to liquid K sources. While MOP is cheaper to apply than Protassium+, its high chloride content poses significant risks to yields. It's also important to note that solution grade Protassium+ alternatives are less expensive than other liquid K sources and safer to apply than potassium thiosulfate.

The Cost of Compromise

Protassium+ vs. MOP

Because almonds are particularly sensitive to chloride, over-application of high chloride potassium sources—like muriate of potash (MOP)—can significantly impact tree health, yield and quality. Applying MOP or even blending it with sulfate of potash may save some money on initial input costs, but could actually end up costing you much more in yield loss at the end of the year.

Check the K Content

Protassium+ vs. Liquid K Sources

While applying liquid potassium through an irrigation system throughout the growing season can be convenient, it’s important to also understand the limitations and risks that come with some liquid potassium sources.

Many liquid potassium products, like potassium thiosulfate, are lower in actual potassium content when compared to Protassium+. And over-application of those liquid potassium fertilizers can contribute to plant toxicity, causing leaf burn and other tree damage that may reduce yields.

A Better Source

Liquid potassium sources, such as potassium thiosulfate and potassium nitrate, are substantially more expensive to apply than Protassium+ and offer no significant advantage in yield performance.

As a dry source of potash, Protassium+ offers the added benefit of enabling potassium reserves to be stored in the soil for future use. Protassium+ also contains 17% valuable sulfur in sulfate form, and it has the lowest chloride content of all major potassium sources.
