Organic soft rock phosphate fertilizer is a natural, slow-release mineral fertilizer mined from ancient marine deposits. In South Africa, Langfos is the only organic sedimentary phosphate product of its kind, offering a unique composition rich in essential nutrients like phosphorus, calcium, and trace elements.
Farmers across the country are increasingly turning to this eco-friendly input to improve soil health, boost crop yields, and reduce dependency on synthetic fertilizers.
Understanding the Composition of Organic Soft Rock Phosphate
Langfos, South Africa’s leading organic soft rock phosphate, contains:
- 8–10% Phosphorus (P) – primarily in the form of tricalcium phosphate, which becomes plant-available through microbial activity and mild soil acidity.
- 20% Calcium (Ca) – vital for root strength, cell development, and soil structure.
- Trace Elements – including zinc (Zn), magnesium (Mg), iron (Fe), and molybdenum (Mo), all of which contribute to plant resilience and balanced nutrition.
Unlike soluble synthetic fertilizers, Langfos releases nutrients gradually, reducing leaching and aligning with the natural uptake rhythms of crops.
How It Works in the Soil
When applied to the soil, organic soft rock phosphate interacts with acid clay particles.
These clays exchange their acidity for calcium from Langfos, simultaneously converting phosphate into an acid-soluble form that plants can absorb.
This slow breakdown:
- Provides a long-term phosphorus source for crops.
- Enhances soil microbial activity.
- Improves overall soil fertility and structure.
This process ensures that nutrients are released steadily, improving uptake efficiency and minimizing environmental runoff.
Key Benefits of Organic Soft Rock Phosphate Fertilizer
1. Sustainable Nutrient Supply
Langfos provides long-lasting phosphorus that remains in the root zone, supporting crops over multiple seasons with fewer applications.
2. Improves Soil Health
By supplying calcium and trace minerals, Langfos improves soil pH balance and encourages the growth of beneficial microorganisms.
3. Supports Root and Shoot Development
Phosphorus is essential for early root development and energy transfer in plants. Langfos supports robust seedling establishment and shoot growth.
4. Reduces Dependence on Synthetic Fertilizers
With rising concerns over chemical runoff and soil degradation, Langfos offers a natural alternative that aligns with regenerative and organic farming principles.
Application Best Practices
- Timing: Apply during soil preparation or early in the growing season.
- Rate: 100–1500 kg/ha depending on crop needs and soil test results.
- Placement: Broadcast or banded applications are effective, followed by light incorporation into the soil.
Soil testing is recommended to determine the correct application rate and to maximize efficiency.
Ideal for South African Conditions
Langfos is particularly effective in South Africa’s acidic and nutrient-depleted soils.
It is registered with the Department of Agriculture as a Group 2 Fertilizer (Reg. B4038) and complies with organic standards, making it ideal for farmers focused on sustainable production.
Whether used in maize fields in the Free State, vineyards in the Western Cape, or sugarcane plantations in KwaZulu-Natal, Langfos adapts to a wide range of climatic and soil conditions.
Long-term Soil Fertility
Organic soft rock phosphate fertilizer like Langfos is a powerful tool for South African farmers seeking to improve soil health, enhance yields, and farm more sustainably.
By leveraging its slow-release properties and balanced mineral profile, farmers can build more fertile soils and reduce long-term input costs.
If you’re looking to reduce your reliance on chemical fertilizers and invest in long-term soil fertility, Langfos organic soft rock phosphate is the natural solution you need.
