Quantum K36
Quantum K36 — a liquid ballast-free potassium fertilizer with K₂O 360 g/l in compounds with organic acids for foliar feeding during fruit formation and ripening.
Main advantages
- K₂O 360 g/l with organic acids — no ballast
- Organic acids — ripening and taste of fruit
- Pome and stone fruit 2.0 l/ha — fruit growth to harvest
- Onion, garlic 4.0 l/ha — bulb formation
- Not with herbicides at early stages — caution
Overview
About this product
Quantum K36 — a ballast-free potassium fertilizer, "organic" potassium: 360 g/l of K₂O as compounds with organic acids, enriched with a complex of organic acids and, optionally, micronutrients. pH 6.5–8.0, density 1.40–1.47 kg/l. Per the maker, organic acids are quickly assimilated and converted into carbohydrates, which improves the ripening and taste of fruit and berries, and potassium is effectively taken up through the leaves.
It is applied as a foliar: wheat, barley and oilseed rape 1.0 l/ha, soybean, pea, pome fruit, stone fruit, berry crops and potato 2.0 l/ha, tomatoes and carrot 3.0 l/ha, onion, garlic and nut 4.0 l/ha.

With potassium 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, but do not combine feeding with herbicide treatment at the early stages of plant development
Before mixing, check compatibility: a test spray solution must not form a precipitate, slight turbidity is acceptable

Questions & answers
What farmers ask most
- Rates depend on crop, prior history and soil analysis. This is a straight fertiliser, not an NPK complex at 150–300 kg/ha. An agronomist sets the dose from nutrient offtake.
