Magnesium Lime — a double benefit in a single granule

Magnesium deficiency is one of the most underestimated problems on Polish fields, especially on light, acidified soils. Bluebird Magnesium Lime addresses it while liming — in a single granule it delivers calcium that regulates pH and magnesium essential for photosynthesis. That is a double benefit in one pass of the spreader.

Two elements, two different jobs

  • Calcium (CaCO₃ 60%) — neutralises toxic aluminium, raises pH and builds the soil's crumb structure.
  • Magnesium (MgCO₃ 30%) — is the central atom of the chlorophyll molecule, so it directly determines the efficiency of photosynthesis.
  • Micronutrients (B, Fe, Zn, Cu, Mn) — support nutrient management and plant resistance.

Why it is worth combining liming with magnesium

On acidic soils magnesium is poorly available, and its deficiency shows up as chlorosis and a yield drop despite correct NPK fertilisation. Supplying calcium and magnesium at the same time eliminates cause and effect in a single operation — the soil regains its reaction and the plant receives the missing element.

  • Saving time and fuel — one pass instead of separate liming and magnesium fertilisation.
  • High reactivity of 93% — fast and predictable action in the soil.
  • Even 3–6 mm granule — clean, uniform spreading with no dust.

Which crops it especially suits

  • Oilseed rape, beet and maize — species with a high magnesium requirement.
  • Light, acidified soils where magnesium is least available.
  • Sites after years of intensive potassium fertilisation, which limits magnesium uptake.
