Why Almonds Trees Need Potassium & Sulfur | Protassium+®

High K

The Need for Potassium

In almonds, there is a high depletion rate of potassium (K) from the soil. Almond trees can remove as much as 55 lbs. of potassium from the soil per 1,000 lbs. of nuts produced1.

Potassium needs to be replenished to optimize tree health and help ensure consistent almond yields year after year.

Skipping a potash application in the fall can deprive almond trees of vital nutrients they need for strong growth and development throughout the spring. Once they're below adequate levels of potassium, it can take those trees years to rebuild proper leaf K concentrations to optimal balance. 

Worse yet, attempting to compensate with heavy application of some other potassium sources in the spring can lead to leaf damage and even potential yield loss. That's especially true if you apply fertilizers high in salt or chloride.

Keep in Mind

Sulfur Considerations

Sulfur deficiencies in the soil have become more common in recent years due to a number of factors:

  • Higher air quality standards
  • Increased crop yields
  • Use of relatively sulfur-free nitrogen and phosphorus fertilizers

Protassium+® fertilizer gives your trees the double benefit of sulfate of potash that's naturally low in chloride, plus 17% sulfate sulfur built in.
