Dolomite Lime (Coarse)

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), providing the same soil benefits as our powdered and granulated options in a slow-release, coarse texture. Ideal for gardens, lawns, raised beds, and bulk soil applications, it helps correct acidic soils, improve nutrient availability, and support strong root development over time. 🌿 Key Benefits Raises acidic soil pH toward the optimal 6.0–7.0 range Supplies calcium (20%) and magnesium (10%) Enhances nutrient availability and soil structure Supports microbial activity and long-term soil health Suitable for soil blending, field application, or topdressing 🌱 Application Guidelines General Maintenance: Apply 400–600 g per 10 m² (1–1.5 lbs per 100 ft²) for routine pH maintenance. Moderately Acidic Soils (pH 5.5–6.0): Apply 600–1,000 g per 10 m² (1.5–2 lbs per 100 ft²). Highly Acidic Soils (pH below 5.5): Apply up to 1,500 g per 10 m² (3 lbs per 100 ft²). For best results, apply in split applications spaced several weeks apart. Soil Testing: For precise pH correction, soil testing is recommended to determine exact lime requirements based on soil texture, buffering capacity (CEC), and existing nutrient levels. Application Rate Guide Use Case Rate Maintenance 400–600 g per 10 m² (1–1.5 lbs per 100 ft²) Moderate Acidity 600–1,000 g per 10 m² (1.5–2 lbs per 100 ft²) High Acidity Up to 1,500 g per 10 m² (3 lbs per 100 ft²) 🚜 Application Methods Gardens, Lawns & Raised Beds: Evenly broadcast and incorporate into the top 10–15 cm (4–6 inches) of soil where possible. Field & Large-Scale Use: Apply using a broadcast or drop spreader for uniform coverage. Incorporation through tillage improves effectiveness, though surface applications can be used where incorporation is not practical. Soil Blending: Mix directly into soil or growing media prior to planting for consistent distribution. 💧 Activation Water thoroughly after application or apply ahead of rainfall to initiate soil reaction and movement into the root zone. 📌 Rate Guidance & Soil Considerations Application rates are based on average loam soils and should be adjusted depending on soil conditions: Sandy soils (low CEC): require lower rates and respond quickly Clay or organic soils (high CEC): require higher rates and respond more slowly Soils with similar pH levels can require significantly different lime applications due to differences in buffering capacity. 🔍 Usage Notes & Agronomic Guidance Soil testing is strongly recommended before application, especially for larger areas. Lime requirements depend on soil texture, buffering capacity (CEC), and existing calcium and magnesium levels. Over-liming can raise pH too high, reducing availability of key nutrients such as iron, manganese, and phosphorus. Avoid using dolomitic lime in soils already high in magnesium, particularly in clay soils. In these cases, use calcitic (high-calcium) limestone instead. Apply 4–8 weeks prior to planting to allow time for pH adjustment. Fall and early spring are ideal application windows. Avoid applying alongside high-phosphorus fertilizers (e.g., rock phosphate or bone meal), as elevated pH can reduce phosphorus availability.
