Ultrasol® K Plus and Qrop® KN helps to increase yields

Side dressing potatoes with Ultrasol® K Plus and Qrop® KN helps to increase yields

  • Potato plants absorb large quantities of nitrogen and potassium throughout the growing season. lt is important that nitrogen and potassium availability to the plant is as high as possible. 
  • Potassium nitrate fertilizers such as Ultrasol® K Plus or Qrop® KN provide readily available sources of nitrogen and potassium that are quickly absorbed in comparison to potassium chloride or potassium sulfate fertilizers. 
  • Potassium nitrate fertilizers such as Ultrasol® K Plus or Qrop® KN are very effective in sidedress applications during early crop growth. 

Ultrasol® K Plus and Qrop® KN helps to increase tuber yield and size distribution

  • Sidedress potato plants with Ultrasol® K Plus and Qrop® KN increased tuber yield and tuber size distribution of Canela Russet. 
  • Many of the treatments that involved sidedress with Ultrasol® K Plus or Qrop® KN up to row closure increased total marketable (> 4 ounces), premium size (> 6 ounces), and medium size tuber yield compared to potato plants that did not receive any sidedres with Ultrasol® K Plus or Qrop® KN. 
  • Alternate sidedress with Ultrasol® K Plus or Qrop® KN up to row closure increased total and marketable (> 4 oz) tuber yield by 28% and 32%, respectively, when compared to pre-plant application of potassium sulfate without Ultrasol® K Plus or Qrop® KN at sidedress. 

Growers can see the difference 

Growers can see the results for themselves - sidedressing potatoes with Ultrasol® K Plus or Qrop® KN up to row closure helps to increase potassium uptake throughout the growing season which enhances early tuber bulking and increases tuber yield.
