Dolomite Lime (Coarse)

Raises Soil pH • Adds Calcium & Magnesium • Improves Soil Structure

Our Coarse Dolomite Lime is a crushed form of dolomitic limestone (calcium and magnesium carbonate), offering the same soil benefits as our powdered and granulated options in a coarser texture that is slow-release. It is ideal for gardens, lawns, raised beds, and soil blending, it helps correct acidic soils, improve nutrient availability, and support healthy root development.

🌿 Key Benefits

  • Raises acidic soil pH into the ideal 6.0–7.0 range
  • Provides calcium (20%) and magnesium (10%)
  • Improves nutrient availability and soil structure
  • Supports microbial activity and overall soil health
  • Suitable for mixing into soil or bulk applications

🌱Application Guidelines

Apply 400–600g per 10m² (approx. 1–1.5 lbs per 100 ft²) for seasonal pH maintenance.

💧 Tip: Water in well after application. For clay-heavy or highly acidic soils, consider applying in two smaller doses spaced a few weeks apart.

📌 These rates are based on average loam soil. Lighter sandy soils may require less, and dense clay soils may require more.

🔍 Usage Notes & Pro Tips

  • Always test your soil pH first using a home kit or lab analysis before applying lime. Overliming can raise pH too high and lock out nutrients such as iron, manganese, and phosphorus.

  • Do not use dolomitic lime if your magnesium levels are already high (especially in clay soils). In that case, use limestone, a high-calcium, magnesium-free option ideal for raising pH without adding more magnesium.

  • Apply at least 4-8 weeks before planting to allow time for pH to adjust. Earlier is better—fall and early spring are ideal.

  • Mix thoroughly into the top 10–15 cm (4–6 inches) of soil for best results, especially in garden beds. Surface application is less effective unless followed by consistent rain or irrigation.

  • Avoid applying lime at the same time as high-phosphorus fertilizers—especially rock phosphate or bone meal—as high pH can reduce phosphorus availability.

  • Re-test your soil pH every 1–2 years if you’re using Dolomite lime regularly. The effect of Dolomite lime is long-lasting, and repeated use without testing can lead to nutrient imbalances.
