Glacial rock dust is a natural product sourced from ancient glacial sediments. This powdered product is rich in essential minerals and trace elements, making it a highly effective soil amendment for promoting healthy plant growth. Glacial rock dust offers many benefits for gardeners and farmers, from improving soil structure to balancing pH levels and enhancing plant nutrition.   

 Here are some of the ways that Glacial Rock Dust can benefit plants and soil:

  • Provides a diverse range of minerals: This Glacial Rock Dust is sourced from natural glacial sediments in the Okanagan Valley that have been excavated and reduced to fine-size fractions, making it a rich source of essential minerals and trace elements. These include silica, calcium, magnesium, iron, and potassium, which can provide a wide range of essential nutrients for your plants.
  • Improves soil structure: The fine texture of glacial rock dust can help improve soil structure by increasing porosity and water-holding capacity. This can improve root penetration and support healthy plant growth. Adding to heavy soils can enhance drainage; sandy soils can help retain moisture.
  • Balances soil pH: This Glacial Rock Dust has a pH of around 6-7, which can help neutralize acidic soils and create a more neutral growing environment for your plants. When soil pH levels are too low or too high, it can limit the availability of specific nutrients to plants, leading to stunted growth and poor yields. By helping to balance soil pH levels, glacial rock dust can help ensure your plants have access to all the necessary nutrients. 
  • Boosts microbial activity: The minerals in glacial rock dust can help promote the growth of beneficial soil microbes, which can help break down organic matter and release nutrients to your plants. These microbes are essential for maintaining healthy soil and can help reduce disease and pest problems in your garden.
  • Enhances plant nutrition: Glacial rock dust provides a balanced mix of essential minerals and trace elements, enhancing the nutritional value of plants, and leading to healthier and more vigorous growth. This can result in better yields and better flavour in fruits, vegetables, and flowers. 
  • Supports sustainable agriculture: Glacial rock dust is a natural and sustainable product. By using it as a soil amendment, you can support sustainable agriculture practices that minimize the use of synthetic chemicals and reduce the environmental impact of farming.

 Glacial rock dust is a highly effective soil amendment that can improve soil structure, balance pH levels, boost microbial activity, enhance plant nutrition, and support sustainable agriculture. Using it in your garden can create a nutrient-rich growing environment that supports healthy and vibrant plant growth and delicious and nutritious produce.
