In the world of soil improvers, there are various products used to promote soil health and fertility. Three common options are seaweed lime, seashell lime, and ordinary lime. But what exactly are the differences between these products, and when should you use each? Let’s take a closer look at each of these soil improvers.

Algae Lime

Algae lime is a natural lime derived from fossilized algae. It is used to deacidify, improve, and enrich the soil with calcium. This promotes a healthier turf, stronger plants, and a more stable soil structure – completely natural and sustainable.

Seashell Lime

Seashell lime, as the name suggests, is obtained from ground seashells. It is a natural source of calcium carbonate, which helps raise the pH of acidic soils. Seashell lime also contains trace elements and can help improve soil structure. Due to its slow release of nutrients, seashell lime is often used as a long-term soil improver.

Ordinary Lime

Ordinary lime, also known as agricultural lime or calcium carbonate, is usually obtained from limestone. It is used to raise the pH of acidic soils and neutralize acidity. Ordinary lime does not contain trace elements, but it can still be useful for improving soil structure and promoting healthy plant growth.

Differences in Applications

Although algae lime, seashell lime, and ordinary lime can all help improve soil quality, there are some differences in their applications. Algae lime, for example, is particularly suitable for organic gardens due to its natural origin and rich nutrient profile. Seashell lime is often used to raise the pH of acidic soils and for long-term soil improvement. Ordinary lime is effective for quick pH correction but does not provide the same nutrients as algae lime or seashell lime.

Conclusion

Choosing the right soil improver depends on several factors, including the specific needs of your soil, crops, and desired results. Algae lime, seashell lime, and ordinary lime are all valuable options, each with its own unique benefits. By understanding their applications and properties, you can make the best choice to promote soil health and fertility.

A key tool for making the correct choice remains, of course, a soil analysis. Do not hesitate to contact us if you have any doubts or questions!
