Improve Soil Quality with Dolomite Lime

OGS Dolomite Lime is a premium calcium-based liming agent designed to enhance the quality and yield of your crops. With a long history of usage dating back to the Roman Empire, dolomite lime provides numerous benefits to the soil while maintaining its pH buffering capacity.

Features and Benefits

  • Reduces soil acidity: Dolomite Lime works to reduce soil acidity levels, promoting healthier plant growth.
  • Rich source of Calcium and Magnesium: Provides essential nutrients for plant growth in moderate, consistent levels, avoiding the peak and trough situation.
  • Boosts humate and humus formation: Assists in the formation of crucial soil components which improve soil structure and fertility.
  • Supports vital microbial bacteria: Promotes the growth of microorganisms responsible for breaking down essential minerals such as phosphorous and silica.
  • Increased nutrient availability: Overall, dolomite lime promotes a greater quantity and diversity of nutrients available for plant uptake.

How to Use

  1. If your soil mix also contains oyster shell flour, use 1/4 cup of dolomite per 25L of soil.
  2. If your soil mix does not contain oyster shell flour, use 1/2 cup of dolomite per 25L of soil.
  3. Mix well to ensure that the dolomite lime is evenly distributed throughout the soil.
  4. Adjust dosage and reapply as needed based on your particular soil type and requirements for maintaining optimal pH and nutrient balance.

Aqua Gardening Suggests These are Best For

OGS Dolomite Lime is ideal for gardeners and growers looking to improve their soil's fertility, structure, and nutrient availability. It is suitable for various types of plants and ensures healthy growth by maintaining a balanced pH and providing essential nutrients. It is especially beneficial for those with acidic soils or soils lacking calcium and magnesium.


What are the main benefits of using Dolomite Lime in my garden?

Dolomite Lime is an excellent source of calcium and magnesium, which are both essential nutrients for plant growth. It helps reduce soil acidity, improves soil fertility, assists in the formation of humate and humus, and supports vital microbial bacteria that aid in the breakdown of minerals, making nutrients more accessible to your plants.

How does Dolomite Lime affect soil pH?

Dolomite Lime acts as a buffering agent, helping to stabilize and maintain the soil pH levels within a desirable range for optimal plant growth. It is particularly beneficial for soils that are acidic, as it raises the pH and enhances nutrient uptake.

Can Dolomite Lime be used in both indoor and outdoor gardens?

Yes, Dolomite Lime is suitable for both indoor and outdoor applications. It can be incorporated into your soil mix or applied as a top dressing in your garden beds, pots, and containers.

How much Dolomite Lime should I use for my plants?

For soil mixes containing oyster shell flour, we recommend using 1/4 cup of Dolomite Lime per 25L of soil. If your soil mix does not contain oyster shell flour, use 1/2 cup of Dolomite Lime per 25L of soil.

Is Dolomite Lime safe for all types of plants?

Yes, Dolomite Lime is generally safe to use for a wide range of plants. However, it is essential to follow the recommended dosage guidelines and monitor your soil pH to ensure optimal growing conditions.

When is the best time to apply Dolomite Lime to my garden?

The ideal time to apply Dolomite Lime to your garden is during the soil preparation stage, before planting. This allows the lime to interact and blend with the soil properly, adjusting pH levels and enhancing overall soil fertility.

How often should I reapply Dolomite Lime to maintain optimal soil pH levels?

The frequency of Dolomite Lime application depends on your soil type, pH levels, and plant requirements. Regular soil testing is recommended to determine the need for any additional lime application. In general, reapplication may be needed yearly or as necessary to maintain proper pH balance and nutrient availability.
