Organics Matter Soft Rock Phosphate 1L

Organic sedimentary rock phosphate mined in South Africa


Over the years sedimentation from cold, mineral-rich fish waters along the West Coast of the Cape have formed valuable deposits which became further enriched by fossil marine and terrestrial animals that contributed threefold to that now shallowly covered phosphate occurrence as it is mined today. 



The total phosphorus content amounts to 8-10% P – expressed as tri-calcium phosphate – 63% of the product is in this form. By repeated extraction, all of it is soluble in 2% citric acid. As an indication of the immediately available fraction, the first extraction dissolves 5% P.

Langfos contains 20% calcium. Because of the link of phosphorus with calcium, its neutralising effect increases by the amount of phosphorus that is taken up. The remainding calcium is in the form of carbonates and silicates.

With the exception of cobalt (Co), which is more important to animals, Langfos provides essential iron (Fe), sulphur (S), magnesium (Mg), molybdenum (Mo) and zinc (Zn). All of them contribute to supplementing soil reserves where Langfos is a regular part of the fertilisation programme.


As Langfos is not water-soluble, it’s a slow-release product that releases phosphate to the plants over many years.. It enriches the soil with trace elements and stimulates root growth and helps with photosynthesis in all plants.


Can be applied according to the need of soil (P) analysis. Langfos won't cause a problem if too much is applied. 

Langfos and ammonium sulphate nitrogen are a good combination, which is further improved if mixed with any organic fertilizer.


recently earthworms were fed Langfos along with other organic food: 20kg of Langfos fed to 8000 earthworms over 8 weeks. The manure was analyzed and there was a significant increase in the phosphate content. The Bemlab analysis below shows the differences. Samples 1 and 2 were earthworm manure where Langfos was fed. This will result in when earthworms are present in soil and Langfos is administered, it will further enrich the soil and increase the P %.


Almost all natural trace elements are present in Langfos.
