Ultrasol SOP is a highly soluble and pure potassium sulfate fertilizer designed to nourish plants during flowering, fruit set, and fruit filling stages. It contains a high percentage of soluble potassium, fortified with sulfur, to improve production quality and enhance the efficiency of vital plant processes. The product helps increase sugar content, improve color and taste, increase fruit size and firmness, and enhance its transportability and storage capacity. It also contributes to improved flowering and fruit set, and increases the efficiency of carbohydrate translocation within the plant. The product is chlorine-free, making it suitable for chlorine- and salinity-sensitive crops and greenhouses. It features rapid dissolution and excellent stability in irrigation systems and preparation tanks, and is compatible with most miscible fertilizers and pesticides.

Foliar fertilization
For crops in the early stages of growth and young fruit trees:
It is used as a 0.5% spray solution.
For intensive plantings in the vegetative stage and for fully grown fruit trees:
It is used in a concentration of 1% to 3% spray solution.
Spraying is best done in the morning or evening to improve absorption and reduce the likelihood of leaf burn.
The spraying is repeated 3 to 4 times during the season as needed.

- 🌿 Orchid's Advice
For best results with Ultrasol SOP, it is recommended to use it during the fruit set and filling stages and before coloring, as potassium helps improve fruit quality and increase sugar content, firmness and taste, while sulfur contributes to improving the efficiency of nutrient absorption and increasing plant vitality, especially when used within a balanced fertilization program that includes calcium and micronutrients during the different stages of production.
