Dokonalý vápník fertilizer
Natural calcium fertilizer approved for use in organic farming.
Perfect Calcium by Hnojík.cz is a natural granular fertilizer made from pure chalk (calcium carbonate), which quickly increases the level of calcium in the soil and improves its pH. It supplies plants with readily available calcium, supporting strong growth, firm leaves and fruits, higher resistance to fungal diseases, and overall better yields. Suitable for vegetables, fruit trees, berries, lawns, and ornamentals.
-
What it can do:
-
Raises available calcium levels in the soil
-
Neutralizes soil acidity (optimizes pH)
-
Improves photosynthesis and plant structure
-
Strengthens resistance to fungal diseases
-
Acts quickly thanks to high reactivity (min. 95%)
-
-
What it cannot do:
-
Not suitable for acid‑loving plants (blueberries, rhododendrons, azaleas)
-
Does not supply nitrogen or phosphorus – needs to be combined with other fertilizers
-
-
Alternatives:
-
Dolomitic limestone (Ca + Mg) – for crops requiring magnesium
-
Ground limestone – slower but longer‑lasting effect
