Rock Phosphate

Mined Rock Phosphate is an excellent natural source of phosphorus and calcium, making it an ideal long-term soil amendment for promoting healthy plant growth. Unlike quick-release fertilizers, Rock Phosphate provides a slow and steady supply of phosphorus over several years, ensuring that your soil remains fertile and productive for extended periods. Additionally, it is a significant source of calcium, which plays a crucial role in strengthening plant cell walls and supporting root development. Mined from natural rock deposits, this organic amendment is perfect for gardeners and farmers looking for sustainable, long-term solutions to soil fertility.

Nutrient Profile and Benefits of Rock Phosphate

Available Phosphorus (P2O5): Rock Phosphate contains 5.0% available phosphorus, which is released slowly into the soil to support root growth, energy transfer, and flower development. Phosphorus is essential for converting nutrients into usable energy, enabling plants to grow strong and healthy.

Total Phosphorus: With 25.0% total phosphorus content, Rock Phosphate offers a significant long-term supply of this critical nutrient. The gradual release of phosphorus ensures that plants have access to this vital element for years to come, enhancing bloom production and root system development.

Calcium (Ca): Rock Phosphate contains 25.0% calcium, an essential nutrient for building strong cell walls, supporting root growth, and improving overall plant resilience. Calcium also helps to neutralize soil acidity and improve soil structure, promoting better water retention and nutrient absorption.

Long-Term Nutrient Release: One of the primary benefits of Rock Phosphate is its ability to release nutrients slowly over several years. This makes it an ideal choice for long-term soil health and fertility, especially for perennials, fruit trees, and other plants that benefit from sustained nutrient availability.

Application Recommendations

Rock Phosphate can be applied in various ways to provide a steady supply of phosphorus and calcium to plants. The following application rates are recommended to ensure optimal soil enrichment and plant growth.

In the Garden: Apply up to 20kg per 100m² (44lbs per 1000ft²) by gently mixing it into the top 5cm (2 inches) of soil. This application should be done annually to provide a long-term supply of phosphorus and calcium to support healthy plant growth.

Top Dressing: For individual plants, apply 15-30ml (1-2 tablespoons) per plant, or 15ml per 4L (1 tablespoon per gallon) of soil, up to once per month. This method provides a steady release of nutrients to support flowering and root development.

Premixing Soil: When preparing soil for planting, mix 45ml per 4L (3 tablespoons per gallon) of soil. For larger volume soil mixing, add up to 5kg (11lbs) per cubic yard of soil. This ensures that the soil is enriched with phosphorus and calcium before planting, promoting strong root systems and sustained growth.

Weight to Volume Conversion

Rock Phosphate has a specific gravity of approximately 1.72, allowing for easy conversion between weight and volume to ensure precise application.

• Tablespoon (15ml): 26g
• Cup (236ml): 406g
• Litre: 1720g

These conversions ensure that you can apply the correct amount of Rock Phosphate for your specific gardening or agricultural needs.

Recommendation

Mined Rock Phosphate is an exceptional soil amendment for gardeners and farmers seeking a long-term supply of phosphorus and calcium. Its slow-release nature ensures that plants receive a steady supply of these essential nutrients over several years, promoting healthy flowering, root development, and overall plant vitality. Whether you are managing a home garden or larger agricultural fields, we highly recommend Mined Rock Phosphate for its ability to enhance soil fertility and support sustainable gardening practices.
