Andesite

Andesite is a basalt-type rock powder used to remineralize soils with a broad spectrum of naturally occurring trace elements. Volcanic rock dusts are a cornerstone of remineralization and regenerative programs because they slowly release a wide range of minerals and trace elements as they weather, rebuilding the diversity of nutrients that intensive cropping depletes. Beyond nutrition, fine rock powders can support soil structure and biological activity. As a slow-release, broad-spectrum mineral source, it works on a longer timeline than soluble fertilizers, feeding the soil rather than the immediate crop. It suits growers building soil for the long term.
