Almonds: 3 Tips for In-Season K Application


Evaluate your midseason K needs using the three tips below for in-season potassium management.

1. Evaluate bloom conditions and nut set

  • If conditions are favorable for a larger crop, increase in-season application of K to meet the higher potassium demand of almonds. [Almonds remove 96 lbs. of K2O/1,000 lbs. of nuts.]

  • If harvest expectations are less, maintain your current fertility program to support any potential further growth in the season. 

2. Consider fertigation of potassium

  • Places K in the wetting zone and quickly move K to the roots
  • Allows you to target K near fine feeder roots
  • Achieves good uniformity [when applied with properly maintained equipment]

3. Consider a safe and efficient K fertilizer

  • ESP enhanced soluble potash (1-0-8-3) liquid is formulated using Protassium+® premium sulfate of potash.

    • Provides high potassium content and readily available sulfate sulfur

    • Is a true liquid that works great in drip systems microsprinklers

    • Considered very safe – less than 1 percent chloride and a low salt index

    • Requires no additional equipment to handle

  • ESP has multiple advantages over other liquid K sources

    • Multiple nutrients [potassium carbonate has only one nutrient]

    • Lower salt index than potassium thiosulfate and potassium nitrate[1]

    • Priced  competitively with potassium thiosulfate and potassium nitrate, on a per unit of K basis

In addition to actively managing K, find other healthful practices in the California Almond Sustainability Program-Nutrient Management.
