Qrop® K CR 6

Qrop™ K CR is a polymer-coated Controlled Release prilled water-soluble potassium nitrate.

Qrop™ K CR is covered by a superior polymer coating agent, which guarantees a consistent, safe and controlled nutrient release pattern under a wide range of soil temperatures.

The main advantages and benefits of Qrop™ K CR are:

  • Improved nutrient use efficiency and crop safety.
  • Lower nutrient input costs and application costs.
  • Environmentally friendly, as its use reduces the risk of nutrient run-off, ground and surface water pollution, and algae bloom in coastal areas.
  • No premature or "flash" release of nutrients at higher soil temperatures (> 70 °F), which may lead to plant burning, early nutrient depletion, and an increased risk of nutrient leaching.
  • Qrop™ K CR has a thin and pliable coating layer: no cracks or breaks will appear during handling and mixing.
  • With Qrop™ K CR the micro-pores in the coating do not expand as the temperature increases, which results in a more even nutrient release and also prevents the premature release of nutrients, or "flash release". This so-called flash release of nutrients at higher temperatures (> 70 °F) may lead to plant burning, early nutrient depletion, and an increased risk of nutrient leaching. Qrop™ K CR stands for crop and environmental safety, economical use of plant nutrient sources, and brings peace of mind to the end-user.
  • As Qrop™ K CR has a thin and pliable coating layer, no cracks or breaks will appear during handling and mixing. This smooth and uniform coating layer prevents uncontrolled release of nutrients, which makes its use safe for the environment.
  • Qrop™ K CR fits perfectly into an environmentally-sound plant nutrition program, with a reduced risk of nutrient run-off, ground and surface water pollution, and algae bloom in coastal areas. This risk is strongly present in soils with a limited nutrient holding capacity, such as coarse textured, sandy soils, low in organic matter, in combination with heavy rainfall.
  • Therefore, Qrop™ K CR is SQM's answer for improved nutrient use efficiency and crop safety, lower nutrient input and application costs, and is an environmentally-safe solution, which will result in higher marketable yield and grower's income.
