What Is Dolomitic Lime?
Dolomitic lime, also referred to as dolomite, is a naturally occurring limestone product composed of calcium carbonate and magnesium carbonate. It differs from standard agricultural lime by its additional magnesium content, making it highly effective for correcting magnesium deficiencies in soil while also improving calcium levels.
The presence of both calcium and magnesium makes dolomitic lime a dual-purpose soil amendment. It is commonly applied in fields where intensive crop production depletes key nutrients, particularly in soils that tend towards acidity.
Applications in South African Agriculture
Dolomite / Dolomitic lime plays a significant role in maintaining soil health and fertility across a variety of agricultural applications. South African farming, which spans everything from maize and citrus to vineyards and sugarcane, depends on high-quality inputs to ensure long-term viability.
By improving the calcium-to-magnesium ratio in soil and correcting low pH levels, dolomitic lime helps unlock the full nutrient potential of soil, thereby enhancing crop uptake of essential elements such as nitrogen, phosphorus and potassium.
A well-balanced soil pH fosters strong root development, better water retention, and improved microbial activity. These conditions collectively support sustainable agriculture and improved crop yields year after year.

Soil pH Correction and Nutrient Balance
One of the main reasons dolomite / dolomitic lime is widely used in agriculture is its ability to correct soil acidity. Low pH soils hinder nutrient uptake, reduce microbial efficiency, and slow crop growth. In regions of South Africa with naturally acidic soils, regular lime applications form an essential part of crop management plans.
Calcium carbonate raises the soil pH and improves structure, while magnesium carbonate ensures plants have access to this vital secondary nutrient. Without proper magnesium levels, photosynthesis and energy transfer within the plant can be compromised, resulting in lower yields and quality.
The dual-action nature of dolomitic lime makes it a strategic investment for any operation targeting long-term soil health.
Beyond the Basics: Benefits of Soil Amendment
Correcting soil pH is only the beginning. Dolomitic lime, as a soil amendment, contributes to a range of agronomic benefits:
- Improved soil fertility
- Enhanced microbial activity
- Stronger root growth and nutrient uptake
- Reduction in toxic elements like aluminium and manganese
- Better fertiliser efficiency
These factors work together to create a more productive and resilient farming environment. As a reputable lime supplier South Africa trusts, Kalkor ensures that every batch supports these objectives.
Kalkor’s Role in Supporting Sustainable Agriculture
Sustainable agriculture is not just a trend but an essential shift in how farming must evolve. Kalkor is proud to support initiatives and practices that reduce the long-term environmental impact of intensive farming.
Dolomitic lime, when used appropriately, helps reduce dependency on chemical fertilisers by naturally improving the soil’s nutrient-holding capacity. It reduces runoff and the need for excessive inputs, aligning with the principles of regenerative and sustainable agriculture.
Our focus is not only on delivering effective soil treatment products but also on supporting farming communities with long-term, cost-effective solutions.

Product Availability and Guidance
Availability of Dolomitic Lime
Kalkor maintains a steady and predictable supply of dolomite / dolomitic lime across multiple farming regions. We understand the seasonal demands of agriculture and work closely with logistics providers to ensure that our customers receive their products when and where they need them.
Expert Advice
To assist clients with application rates, product suitability, and timing, our experienced team is available to offer advice tailored to specific crop types and soil conditions.
The Science Behind Our Products
Our dolomite / dolomitic lime products are based on sound agronomic principles. The use of calcium carbonate and magnesium carbonate as corrective agents is well documented in scientific literature and agricultural studies.
Soil pH correction is not only about neutralising acidity but also about enabling other inputs to function effectively. Fertilisers, composts, and even irrigation are impacted by the soil’s chemical balance. Without the correct pH range, a significant portion of added nutrients remains inaccessible to plants.
By using high-purity dolomite / dolomitic lime, as supplied by Kalkor, farmers can be confident that their soil amendment strategies are grounded in proven science and practical experience.
Commitment to Transparency and Quality
As a supplier with deep historical roots in the fertiliser industry, Kalkor upholds the highest standards in product integrity and client relations. We do not simply offer dolomite; we offer assurance, traceability, and accountability.
Our reputation has been built on decades of customer trust, strengthened by our clear communication, consistent supply, and dedication to agricultural improvement.

Restoring Soil Balance with Calcitic Lime
Many farming regions across Limpopo, North West, and parts of the Free State suffer from acidic soils, often resulting from over-farming, excess rainfall, and fertiliser use. Acidic soil conditions limit nutrient uptake, reduce microbial activity, and stunt crop growth.
Calcitic lime helps neutralise soil acidity by increasing the pH level, making essential nutrients like phosphorus, potassium, and magnesium more available to plants. It also improves soil structure, enhances root development, and reduces the toxic effects of elements like aluminium and manganese.
By adjusting soil pH levels, farmers experience healthier crop growth, improved fertiliser efficiency, and a more resilient agricultural system.
FAQ: Dolomitic Lime and Soil Management
What is the difference between dolomitic lime and agricultural lime?
Agricultural lime generally consists of calcium carbonate, while dolomitic lime contains both calcium carbonate and magnesium carbonate. The latter provides added magnesium for soils lacking this nutrient.
How often should dolomitic lime be applied?
Application frequency depends on soil pH, crop type, and farming practices. A professional soil test is essential to determine the appropriate timing and rate.
Is dolomite / dolomitic lime suitable for all crops?
Most field and horticultural crops benefit from dolomitic lime, especially those grown in acidic soils. However, soil tests should always guide application.
How do I know if my soil needs lime?
Visible signs like poor crop growth or moss can indicate acidity. However, the most reliable method is a professional pH and nutrient analysis.
Where does Kalkor source its dolomitic lime from?
Kalkor sources from several established deposits within South Africa. Full details can be found on our sourcing page.
Can I buy directly from Kalkor?
Yes, direct sales are available to commercial operations. Visit our website for quotations and delivery options.
What are typical lime application rates?
Rates vary from 500 kg/ha to 2,500 kg/ha depending on pH levels and soil structure. Consult with an agronomist or contact Kalkor for guidance.
Does Kalkor offer other soil amendments?
Our core focus is to provide the appropriate recommendations of lime and gypsum suitable for crop plantings, and we work with partners and consultants who provide comprehensive soil fertility strategies.
