Lava - Volcanic Raw Materials

Lava, a volcanic rock that is formed when magma solidifies on the surface of the earth, has become a valuable raw material in the production of mineral substrates. 

Its unique porous structure, resulting from the rapid cooling of magma, makes lava an ideal material to improve soil quality and promote plant growth. 

The role of lava in the production of mineral substrates is based primarily on its ability to efficiently store water and nutrients, while at the same time ensuring excellent drainage. These properties are crucial for creating a healthy root environment. Due to its porous texture, lava enables optimum air circulation in the root area to improve the oxygen supply to the plant roots and reduce the risk of root rot. Another key benefit of lava is its long-term stability. Unlike organic substrates, lava does not decompose, thus retaining its structural properties for years. This longevity ensures a lasting improvement in soil structure without the need to regularly replace the substrate. In addition, lava contributes to the nutrient supply for plants due to its mineral composition. 

While lava itself only contains small amounts of soluble nutrients, it can serve as a natural carrier for fertilizers. The porous cavities in the rock physically store fertilizers, which are then slowly released to the plants, ensuring an efficient supply of nutrients. 

In practice, lava is used in a variety of horticulture and landscaping projects. It is not only used in pure mineral substrates, but also as an additive in potting soils and as a drainage layer in planters and beds. Its versatility and environmental compatibility make lava a preferred material for sustainable horticulture and landscaping concepts.
