Silver-K: Liquid Potassium Fertilizer for Enhanced Fruit Color, Size & Quality
Silver-K is a liquid fertilizer in Green Magic’s Floral and Fruit System category. It is formulated to supply potassium, sulfur, and citric acid to crops during the fruit development and maturation stages.
Silver-K Formulation
The efficacy of Silver-K is based on its precise chemical composition, where each component serves a specific function in plant metabolism.
- Potassium (K): As a primary macronutrient, potassium is fundamental for activating enzymes, regulating water balance within the plant (osmoregulation), and translocating sugars to developing fruits.
- Sulfur (S): Sulfur is a necessary component for the synthesis of essential amino acids (cysteine and methionine) and proteins, which are vital for overall plant health and metabolic efficiency.
- Citric Acid: This organic acid acts as a chelating agent, facilitating the uptake and mobility of potassium and other minerals within the plant’s vascular system, thereby improving nutrient use efficiency.
Composition
- Potassium (K): 20%
- Sulfur (S): 4.5%
- Citric Acid: 10%
Key Benefits
Silver-K is intended to support the following plant physiological processes:
- Fruit Colour Development: It contributes to the natural synthesis of pigments responsible for fruit colour.
- Fruit Sizing and Weight: Silver-K facilitates the transport of sugars and other compounds from the leaves to the fruit, a key process for increasing fruit size and density.
- General Fruit Quality: The nutrient composition is designed to positively influence fruit firmness, sugar content, and post-harvest shelf life.
Application Guidelines
For proper use, apply during the fruit development and maturation phases.
Foliar Spray
For nutrient uptake through the root system.
- Recommended Rate: 300 – 500 ml / 200 litres of water.
- Instructions: Apply to ensure complete coverage of plant foliage for effective absorption.
Fertigation (Soil Application)
For application to the root zone via the irrigation system.
- Recommended Rate: 2 – 3 litres/feddan.
- Instructions: Apply via drip irrigation or other standard fertigation systems.
Note: It is recommended to conduct a small-scale compatibility test before full-scale application. Rates may need adjustment based on crop type, soil analysis, and water quality.
