Overview
About this product
Quantum Calcium (Ca) — a liquid concentrated calcium fertilizer with a high soluble calcium content, enriched with magnesium. It contains 209 g/l of CaO, 126 g/l of nitrogen, 30 g/l of MgO and 2 g/l of boron; pH 4.0–7.0, density 1.40–1.50 kg/l.
Per the maker, the calcium in the product is very mobile and penetrates plants quickly, and the fertilizer strengthens cell walls and improves the suitability of the harvest for transport and storage. On fruit and berry crops, nut, tomatoes, pepper, aubergines, cucumber and cabbage it is applied at 2.0–5.0 l/ha, repeated after 7–10 days.
The maker advises using it separately from other agrochemicals.

With calcium deficiency (by visual or laboratory diagnosis), for all crops, especially fruit, berry and vegetable crops, treatments are repeated at 7–10 day intervals
For best results, feeding is recommended together with other products under the technology schemes for the crop
- Method
Foliar feeding with standard sprayers: spray solution 200–400 l/ha for vegetable crops, 500–1000 l/ha for grapes and fruit crops
- Conditions
Prepare the spray solution immediately before application: fill the tank 2/3 with water and, while stirring, add the components one at a time, waiting until the previous one is evenly mixed
Spray in the morning or evening; optimal air temperature 10–25 °C, wind up to 5 m/s
- Tank mix
Joint application with plant protection products and other fertilizers is possible; before mixing, check compatibility: a test solution must not form a precipitate, slight turbidity is acceptable
In tank mixes, pay particular attention to water quality and the technique of preparing the spray solution

What farmers ask most
- Rates depend on crop, prior history, soil analysis and nutrient status. An agronomist sets the dose from this product's label — not an NPK-complex template of 150–300 kg/ha.
