Description
LS CalciBo Liquid carries the highest calcium load in the range, 16% CaO, paired with boron and a fast-available nitrate nitrogen (N-NO3) carrier. The pairing is deliberate: calcium and boron both cross-link pectin in the cell wall, so together they reinforce tissue structure more directly than calcium alone, while boron’s added role in pollen germination and pollen-tube growth extends the benefit into flowering and fruit set. LS CalciBo Liquid suits programs prioritising maximum calcium delivery, for fruit quality, storage life, and disorder prevention, alongside boron-driven fruit set. It integrates into foliar spray schedules on field vegetables, tree fruit, and vine crops.
Key Benefits
- Reinforces cell wall structure. Calcium and boron both cross-link pectin, giving cell walls the rigidity that underpins fruit firmness and storage quality.
- Supports flowering and fruit set. Boron governs pollen germination and pollen-tube elongation, the process most sensitive to boron shortfall during bloom.
- Feeds the crop with immediately available nitrogen. Nitrate nitrogen is absorbed quickly, keeping feeding responsive through active growth.
- Delivers calcium at the highest concentration in the range. At 16% CaO, LS CalciBo Liquid suits programs with the greatest calcium demand, reducing the need to layer in a separate straight calcium source.
How It Works
Calcium is mobile only in the xylem, so it moves upward with the transpiration stream and, once deposited in cell walls, does not redistribute to new growth. LS CalciBo Liquid answers that by supplying calcium repeatedly, at a higher concentration than the rest of the range, cross-linking with pectin to reinforce cell wall structure, which underpins tissue firmness and resistance to disorders linked to calcium shortfall. The nitrogen it carries is entirely nitrate (N-NO3), the form roots absorb fastest and with the least energy cost, so feeding keeps pace with active growth.
In place of a broader micronutrient package, LS CalciBo Liquid pairs its higher calcium load with boron, which cross-links pectin alongside calcium and governs pollen germination and pollen-tube growth, so the two nutrients reinforce cell wall integrity and support fruit set together.
When to Use LS CalciBo Liquid
LS CalciBo Liquid fits into a program wherever calcium demand is highest and boron support is needed alongside it.
- LS CalciBo Liquid fits flowering and fruit set, when calcium and boron demand peak together.
- LS CalciBo Liquid supports fruit expansion, when calcium’s structural role is most critical.
- LS CalciBo Liquid fits programs needing a concentrated calcium-boron input without a broader micronutrient package.
Rapid fruit growth and low-transpiration conditions, including high humidity, cool or overcast weather, and drought around bloom, can outpace calcium and boron’s movement into developing tissue and raise the risk of related disorders; repeated, split applications through the demand period help keep supply ahead of that risk.
