This natural calcium is ideal for improving soil fertility. It contains min. 95% CaCO ₃ , which means rapid decomposition within 2 months after application. Thanks to its low moisture content (4–8%) , it is quickly released and helps plants absorb nutrients efficiently.
- Increases the level of available calcium in the soil
- Contributes to higher crop quality (tomatoes, apples, strawberries, etc.)
- Improves plant resistance to disease and promotes proper growth
- Very fast effectiveness due to high reactivity
Benefits of proper calcium levels in the soil
- Supports photosynthesis and healthy plant growth
- Improves the strength of cell walls – more durable leaves and fruits
- Increases resistance to fungal diseases
- Ensures optimal fruit and leaf shape
- Helps prevent fruit rot and deformation
Calcium application
- By sprinkling – 0.5 kg per 8 m² of soil, rake or plow in
- Adding to infusions – 1 teaspoon per 1L of water (easily crushed for better solubility)
- Immediate help for plants – crush the granules into powder, make an infusion and water the plants
Not suitable for acid-loving plants because it increases the pH of the soil!
How to recognize calcium deficiency?
- Tomatoes – black spots on the underside of the fruit (“blossom end rot”)
- Peppers, eggplants – same symptoms as tomatoes
- Apples – susceptibility to bitter spot and storage diseases
- Nuts, potatoes, grapevines – deformation, spots, reduced fruit quality
- Celery – the black heart of the plant
- Houseplants – leaf deformation, poor growth
The correct level of calcium in the soil will ensure higher yields and healthy plants!
Dosage and composition
- High reactivity : min. 95%
- Calcium content : min. 95% CaCO₃
