Managing Potassium in Potatoes

Potassium (K) is one of the three essential macronutrients along with nitrogen and phosphorus. Among its key functions are promoting growth and helping potatoes to resist drought and disease.

Vital to plant health

The Role of Potassium

Potassium is required for activation of over 80 plant enzymes and supporting the physiological development of a potato crop. Its benefits include:

  • Improving plants' water use through regulation of photosynthesis and transpiration
  • Enhancing nitrogen utilization and increasing protein production
  • Boosting overall plant health and the crop's ability to withstand disease, pests and drought stress

Symptoms of a potassium deficiency in potato plants include bluish-green leaflets and slight interveinal chlorosis, marginal scorch bronzing and brown spots on the undersurface of leaves.

The Elevated Need for Potassium in Potatoes

Potassium is taken up by potato plants more than any other nutrient. In fact, potatoes remove upt to 56 lbs. of  K2O per 100 cwt of yield. 

Reducing potassium application due to cost concerns may appear to be a short-term solution, but the long-term impact may be even more costly.
