At the heart of South Africa’s move toward sustainable farming is Langfos organic soft rock phosphate fertilizer, a flagship product by Gecko Fert (Pty) Ltd. 

Since its founding in 2010, Gecko Fert has committed itself to producing eco-conscious and high-performing fertilizers tailored to the unique agricultural conditions of South Africa. 

Pioneering Sustainable Agriculture in South Africa

Langfos represents the company’s dedication to soil health, crop performance, and long-term agricultural sustainability.

Our Legacy: From Vision to Agricultural Innovation

With roots planted in the rich soils of Langebaanweg, Gecko Fert Agricultural Solutions has grown into a trusted name in natural agricultural inputs. 

Built on a vision to empower farmers with earth-friendly and effective products, the company has prioritized science, sustainability, and service. 

The relaunch of the Langfos mine in 2010 marked a turning point for the industry, making available once again South Africa’s only organic sedimentary rock phosphate.

Today, Gecko Fert’s influence stretches across farms big and small, from commercial producers to regenerative and organic growers. 

Whether enhancing maize fields in the Free State or nourishing vineyards in the Western Cape, Langfos is revolutionizing how South Africa grows.

What Is Langfos Organic Soft Rock Phosphate Fertilizer?

Langfos is a naturally occurring, sedimentary rock phosphate sourced directly from the West Coast of South Africa. 

Rich in phosphorus, calcium, and trace minerals, this organic soft rock phosphate fertilizer is designed to work in harmony with the soil—supporting long-term fertility, root health, and crop resilience.

Key Composition:

• Phosphorus (P): 8–10% total, mostly in the form of tricalcium phosphate
• Calcium (Ca): Approx. 20%, essential for cell wall strength and nutrient mobility
• Trace elements: Zinc (Zn), magnesium (Mg), molybdenum (Mo), and iron (Fe)

These nutrients are released slowly over time, providing a sustainable and balanced feeding regime that supports soil biology and reduces nutrient loss.

Why Langfos Is the Go-To Choice for Farmers

1. Long-Term Nutrient Supply

Unlike synthetic fertilizers that deliver a quick burst of nutrients followed by leaching, Langfos releases phosphorus and calcium gradually. 

This provides extended feeding to crops and reduces the risk of groundwater contamination.

2. Soil Health Improvement

Langfos enhances microbial activity and encourages root development by maintaining a more stable pH and increasing calcium availability. 

Healthier soil leads to healthier, more resilient crops.

3. Multi-Crop Compatibility

From grains and oilseeds to fruit trees and pastures, Langfos adapts to a wide variety of South African crops. 

Its broad spectrum of nutrients benefits diverse agricultural systems.

4. Certified and Sustainable

Registered with the Department of Agriculture as a Group 2 fertilizer (Reg. B4038), Langfos meets organic standards and is ideal for both conventional and organic farming.

5. Made in South Africa

Langfos is proudly mined, processed, and distributed locally. Supporting Langfos means supporting South African jobs, innovation, and food security.

How Langfos Works in the Soil

Langfos integrates into soil ecosystems through a natural exchange process:

• Acidic clay particles in the soil interact with the calcium in Langfos.
• This exchange releases phosphate ions and trace minerals in a plant-available form.
• Microorganisms further break down the phosphate rock, gradually releasing nutrients in tune with the crop’s uptake rate.

This balanced approach ensures long-term soil fertility without depleting natural resources.

Best Practices for Applying Langfos

When to Apply

• Pre-planting: Ideal for soil preparation
• During planting: Apply as a banded or row fertilizer
• Post-harvest: For soil regeneration and pH balancing

How Much to Apply

• Typical rates range from 100 kg/ha to 1500 kg/ha depending on crop needs and existing soil phosphorus levels.
• Soil testing is recommended for precision fertilization.

How to Apply

• Broadcasting: Spread evenly and incorporate lightly into the topsoil
• Banding: Place in furrows near seed rows for efficient uptake
• Side-dressing: Apply near established plants for targeted feeding

Supporting All Farming Systems

Whether you’re operating a large commercial maize farm or a small-scale permaculture project, Langfos fits seamlessly into your fertilization strategy:

• Organic farms: Langfos meets organic standards, supporting chemical-free production
• Regenerative farms: Encourages microbial life and soil recovery
• Conventional farms: Offers a sustainable alternative or complement to chemical inputs

Gecko Fert’s Broader Commitment to Eco-Friendly Agriculture

While Langfos is our flagship product, Gecko Fert’s portfolio also includes Eco Pellets, a carbon-rich organic pelletized fertilizer that works synergistically with Langfos to improve soil structure, water retention, and microbial activity.

Together, these products form part of a holistic soil enrichment system that helps South African farmers future-proof their operations.
