Aegir Seashell Grit is a slow-release (lime) soil conditioner, rich in Calcium carbonate 96.1%, DM 99.5%

Aegir Sea Shell Lime is a 100% natural source of lime. The shells are cleaned, heated, and ground into a granulate (pieces). Due to this granular form, it dissolves slowly in the soil. As a result, the pH rises slowly, and pH fluctuations can be avoided. In this way, the growth of soil life is stimulated, creating optimum conditions for plant growth. A too rapid rise in pH can damage soil life.

Aegir Seashell Grit is a slow-release calcium soil conditioner, 100% natural product, created by living organisms in the sea.  The shells are cleaned, washed, and heated before being uniformly ground to a coarse grit. This calcium source has a long-lasting effect when applied to the soil, ensuring a stable pH.  The product is also rich in a wide range of trace elements. Aegir Seashell Grit is a rich source of calcium [96.1 % Ca Co3 ] which stabilises the pH and feeds the soil with a wide range of unique minerals and trace elements. A good soil pH is very important for good plant growth. If the pH of the soil is low (acidic), various nutrients are bound in the soil and the plant cannot absorb them. By optimising the pH with Aegir Sea Shell Lime you can counteract acidification.


  • Slower pH increase for the preservation of soil life.
  • Improve the balance of trace elements in the soil.
  • Improve structure and crumbliness of soil.
  • Slower release for 3 years stable pH.
  • Very effective and economical in use.
  • Prolonged effectivity/soil conditioning Keeps the pH of the soil stable Ostrea Seashell Lime has a neutralising value of 54% Suitable for soil maintenance and sweetening

Easy to apply

Content Seashells are composed mainly of Calcium Carbonate (CaCO3) (96.1%) and are packed with essential trace elements. These are of great importance for the vitality of the soil. But they also contain a wide range of minerals and trace elements that benefit soil fertility. The pH value of the soil determines whether these are absorbed properly. If we want to work with the absorbability of these nutrients, the acidity level must remain within certain lines. The pH target zone for different soils: Shell Lime is a 100% natural source of lime.
