NPK 15.15.15
What is NPK 15.15.15 granules?
A balanced granular fertilizer, containing the three major elements in equal proportions: 15% nitrogen, 15% phosphorus, and 15% potassium. The granules are scattered on the soil and dissolve gradually with each watering, feeding the plant for several weeks from a single application.
What's the difference between granules and soluble fertilizer?
- Granules are scattered directly on the soil, and don't need to be dissolved in water.
- They dissolve slowly, feeding the plant for a longer period, and need less frequent repetition.
- They are not used as a foliar spray or in drip systems.
The role of each element
- Nitrogen (N): Activates leaf and stem growth and gives the plant its green color.
- Phosphorus (P): Strengthens roots and supports flower and fruit formation.
- Potassium (K): Improves fruit quality, size, and taste, and strengthens the plant against heat, thirst, and diseases.
Benefits
- Balanced nutrition suitable for all growth stages.
- Feeds the plant for several weeks from a single application.
- Easy to use, scattered directly without preparation.
- Boosts root and leaf growth and supports flowering and fruiting.
- Suitable for fertilizing soil before planting and for periodic fertilization of planted plants.
- Suitable for vegetables, fruits, flowers, trees, grass, and indoor plants.
How to use
- Before planting: Scatter the granules on the soil and mix well with the top layer.
- For planted plants: Scatter the granules around the plant, away from the stem by a distance of 5 to 10 cm, and mix lightly with the soil surface.
- For trees: Distribute the granules around the perimeter of the tree's shade, because the roots that absorb nutrients are there.
- Water directly after scattering until the granules begin to dissolve.
- Repeat the application every 4 to 6 weeks during the growing season.
Quantities
- Small to medium pot (20 to 30 cm): 1 small spoon.
- Large pot: 1 large spoon.
- Vegetable and flower beds: 30 to 50 g per square meter.
- Grass (turf): 25 to 35 g per square meter.
- Small trees: 100 to 300 g per tree.
- Large trees: 500 g to 1 kg per tree.
- Farms: 30 to 50 kg per 1000 square meters.
Start with the lower amount for small plants and new seedlings, and increase it gradually as the plant grows. A small spoon equals approximately 5 g, and a large spoon equals approximately 15 g.
Important tips
- Do not exceed the specified amount, because excess burns the roots.
- Do not place the granules touching the stem or on the leaves.
- Do not scatter it on completely dry soil, and always water after scattering.
- If granules fall on the leaves, shake them off or wash them with water.
- For best results, use it with a soil improver such as humic acid.
Storage and safety
- Store in a dry, cool place away from sunlight and moisture, and close the container well after each use.
- Keep out of reach of children and pets.
- Avoid contact with eyes, and wash your hands after use.
