Uses of Ultrasol SOP potassium fertilizer in agriculture
Used in crops that need to raise potassium levels during production stages, such as vegetables, fruits, protected crops, fruit trees, and plants requiring improved fruit quality.
Also suitable for programs requiring high potassium without adding nitrogen, especially when directing the plant toward flowering and fruiting instead of excessive vegetative growth.
Can be combined with other agricultural fertilizer products based on crop needs, and with soil and growing media products when preparing a suitable growth environment, especially in protected cultivation or container planting.
When should Ultrasol SOP fertilizer be used?
Preferably used during stages when the plant’s potassium needs increase, such as the beginning of flowering, setting stage, fruit growth, and before harvest depending on the crop type.
Can also be used when there is a need to improve color, firmness, and fruit quality, provided it is part of a balanced fertilization program that does not cause an uncontrolled increase in salts or elements.
How to use Ultrasol SOP fertilizer
Applied through irrigation fertilization or according to the fertilization system used on the farm.
The dose is determined based on the crop type, plant age, growth stage, and soil or water analysis.
It is preferred to dissolve the fertilizer well in water before pumping into the irrigation network.
Do not mix randomly with fertilizers or pesticides without ensuring compatibility.
It is recommended to follow an agricultural engineer’s advice when used in commercial crops or intensive programs.
Important precautions when using potassium sulfate
Avoid overuse to prevent increasing soil salinity or irrigation solution.
Do not rely solely on potassium; the plant needs a balanced nutrition program according to the stage.
Monitor the plant’s condition when using the fertilizer with sensitive crops or in enclosed growing environments.
Store the product in a dry place away from direct humidity.
Seal the bag properly after opening to maintain fertilizer quality and prevent caking.
