Overview
About this product
Quantum Calcium Pro (Ca) — a liquid concentrated calcium fertilizer with magnesium and amino acids of plant origin. It contains 202 g/l of CaO, 25 g/l of MgO and 50 g/l of amino acids; pH 6.0–7.8, density 1.30–1.40 kg/l.
There is no mineral nitrogen, which, per the maker, rules out stimulation of secondary shoot growth. Per the maker, the fertilizer strengthens cell walls and improves the storability and transportability of produce.
Pome fruit, stone fruit, grapes, nut are treated at 0.3–0.5 l/100 l, currant, raspberry, gooseberry at 0.6–1.2, strawberry at 0.8–1.6, tomatoes, pepper, aubergines, cucumber, cabbage at 2.5–5.0 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

Questions & answers
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.
