Key Features:

Calcium and Magnesium Source: Provides essential calcium carbonate and magnesium carbonate, crucial for healthy plant growth and soil structure.
Acidity Neutralizer: Helps neutralize soil acidity, promoting a balanced pH and encouraging the growth of beneficial microorganisms.
Slow-Release Formula: Takes longer to dissolve in the soil compared to calcitic limestone, offering extended soil pH moderation.
#80 Grit Size: Fine grit ensures even distribution and effective soil integration.

Benefits:

Improves Soil Structure: Adequate calcium helps break apart heavy soils, creating a lighter, more aerated soil, while magnesium aids in nutrient uptake.
Enhances Nutrient Availability: Balancing soil pH can significantly improve the availability of nutrients to plants, fostering robust growth and crop production.
Long-Lasting Effects: The slow-release nature of dolomitic limestone provides sustained benefits over time, reducing the need for frequent applications.

Usage Considerations:

High Magnesium Soils: Avoid use in soils with high magnesium content, such as clay and clay loam soils, to prevent soil binding and weed proliferation.
Low Magnesium Soils: Ideal for sandy, quick-draining soils with a calcium-to-magnesium ratio of 6:1 or greater, indicating magnesium deficiency.
pH Balancing: Best used in soils with a pH below 7 to neutralize acidity and improve soil health.

Application Instructions:

General Use: Consult with a certified agronomist to determine the specific application rate for your soil type and requirements.

Storage Instructions:

Store in a cool, dry place to maintain product integrity and effectiveness.

Enhance your soil with Black Swallow Dolomitic Limestone #80 Grit. This dual-purpose amendment supplies essential calcium and magnesium while balancing soil pH, ensuring healthier, more productive plants. Perfect for gardeners looking to improve soil quality naturally.
