Dry and Liquid
Application Methods
Potassium fertilizer can be applied in granular form through banding or directed broadcasting in the sprinkler-wetted area. It can also be applied in liquid form through an irrigation system.
A granular application of Protassium+ in the fall is ideal for recharging potassium-depleted soils and making the nutrients readily available for the growing season. Dry application also helps to maintain valuable soil reserves that liquid-only applications may not preserve.
In some cases, a liquid potassium application can be used to supplement deficient soils throughout the growing season. However, it’s important to note that some liquid sources of potassium come at a premium price, and they can even lead to plant toxicity and reduced yields if over-applied.
When supplemental potassium is needed, consider an in-season application of dry or liquid form of Protassium+ -- both are usually less expensive and safer than most other liquid forms of potassium.
