Greensand - Frankia Fertilizers

Greensand is a highly beneficial organic soil amendment that consists of the mineral glauconite, which is rich in essential nutrients such as potassium, iron, magnesium, and a variety of other trace elements. These nutrients are crucial for promoting healthy plant growth, improving soil structure, and supporting a thriving soil ecosystem. Greensand is particularly valued for its slow-release properties, providing a steady supply of nutrients to plants over time. By incorporating Greensand into your gardening practices, you can enhance soil fertility and improve the overall health of your garden or agricultural crops.

Nutrient Profile and Benefits of Greensand

Glauconite: The primary mineral in Greensand, glauconite, is a natural source of potassium, which is essential for regulating water balance in plants, promoting strong root systems, and enhancing overall plant vigor. Additionally, glauconite contains iron and magnesium, both of which play vital roles in photosynthesis and energy production within plants.

Potassium: Potassium is a key nutrient for plants, aiding in water regulation, enzyme activation, and photosynthesis. It also enhances the plant's ability to resist disease and stress, leading to more resilient and productive crops.

Iron: Iron is critical for the formation of chlorophyll, which plants need for photosynthesis. Adequate iron levels in the soil ensure that plants have vibrant, green foliage and efficient energy production.

Magnesium: Magnesium is a central component of chlorophyll molecules, making it essential for photosynthesis. It also plays a role in activating enzymes that are necessary for plant growth and development.

Trace Elements: In addition to potassium, iron, and magnesium, Greensand provides a broad spectrum of trace elements that contribute to overall soil health and plant nutrition.

Application Recommendations

Greensand is versatile and easy to apply, making it suitable for various gardening and agricultural applications. The following application rates are recommended to ensure optimal soil enrichment and plant growth.

In the Garden: Apply up to 20kg per 200m² (44lbs per 2000ft²) by gently mixing it into the top 5cm (2 inches) of soil. This application can be done annually or as needed, depending on the nutrient requirements of your soil.

Top Dressing: For individual plants, apply 15-30ml (1-2 teaspoons) per plant, or 15ml per 4L (1 teaspoon per gallon) of soil, up to once per month. This method provides a direct boost of nutrients to support ongoing plant health.

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 helps to create a nutrient-rich growing medium that supports strong root development and healthy plant growth.

Weight to Volume Conversion

Greensand has a specific gravity of approximately 1.19, allowing for easy conversion between weight and volume to ensure precise application.

• Tablespoon (15ml): 18g
• Cup (236ml): 281g
• Litre: 1190g

These conversions help you apply the correct amount of Greensand for your specific gardening or agricultural needs.

Recommendation

Greensand is an excellent soil amendment for gardeners and farmers looking to improve soil fertility and support healthy plant growth. Its rich content of potassium, iron, magnesium, and other trace elements, combined with its slow-release properties, make it an invaluable tool for enhancing soil health and promoting robust plant development. Whether you are maintaining a home garden or managing large agricultural fields, we highly recommend Greensand for its ability to naturally remineralize soil and support sustainable gardening practices.
