What is Blucon 12-12-17?
A complete blue granular fertilizer, containing the major elements: 12% nitrogen, 12% phosphorus, and 17% potassium, with 2% magnesium and micronutrients. The granules are scattered on the soil and dissolve gradually with each watering, feeding the plant for several weeks from a single application. It is considered one of the most popular granular fertilizers used in gardens and farms.
Role of each element
- Nitrogen (N) 12%: activates leaf and stem growth and gives the plant its green color.
- Phosphorus (P) 12%: strengthens roots and supports flower and fruit formation.
- Potassium (K) 17%: its ratio is the highest, it improves fruit size, color, and taste, and strengthens the plant against heat, thirst, and diseases.
- Magnesium (Mg) 2%: essential for chlorophyll formation, keeps leaves green and prevents yellowing.
- Micronutrients: treat leaf yellowing and weak growth caused by a lack of iron, zinc, and manganese, which is a common problem in Kuwait's alkaline soil.

How to use
- Before planting: scatter the granules on the soil and mix them 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 tree's shade perimeter, because the roots that absorb nutrients are there.
- Water directly after scattering so the granules start to dissolve.
- Repeat the application every 6 to 8 weeks during the growing season.
