Main advantages:
  • Complete nutrients formula.
  • Totally water soluble.
  • Specially designed for blueberry.
  • Perfect quantity and equilibrium between all nutrients.
  • Best nitrogen utilization by the crop due to its balanced percentage of nitric nitrogen and ammonium.
  • It assures an adequate vegetative and productive development.
  • Easy to manage and for injecting.
  • Exact dose.
  • Micronutrients supply: B: 0,02% / Zn: 0,04% / Fe: 0,01% / Cu: 0,01%
Considerations:
  • The recommended product quantity must be divided by the number of irrigations to be made between each phenology stage.
  • The resultant quantity to be applied per irrigation must be injected during the 80% of the irrigation period.
  • The nutrient, before to be injected to the irrigation water, must be pre-diluted to generate a concentrated solution (mother solution; 10% is recommended).
  • Control that the electric conductivity of the irrigation water with the nutrient at the emission outlet does not exceed 1.5 mmhos/cm (0.9 g of product/liter).
  • Do not mix Calcium Nitrate with Ultrasol® Blueberry in the same mother solution tank. Apply to separate tanks o separate irrigations.
Usage recommendations are only orientation guides; consequently SQM suggests adjusting them according to the agronomist adviser recommendations.
