rock dust or azomite?
Granite dust, for instance, contains lots of potassium—the K in the NPK fertilizer ratio. Rock phosphate, a 'single dust' that's available in packages at most garden centers, just supplies phosphorus. But ground basalt (pronounced "ba-salt") contains a nicer mix—phosphorus, potassium, calcium, magnesium and iron." "But rock dust alone …

Apatites in lunar KREEP basalts: The missing link to …
In non-KREEP mare basalts, phosphate saturation occurs very late, probably after more than 96% crystallization (e.g., Sha, 2000; Tartèse and Anand, 2013). KREEP basalts are enriched in P (e.g., Taylor et al., 2012), so it is likely that phosphate saturation occurs earlier, after around 85%–90% crystallization (Harrison and Watson, 1984).
Amending highly weathered soils with finely ground basalt …
In some soils phosphate sorption was significantly reduced by crushed basalt application. Furthermore, 'available' P as measured by extraction with 0.005 M H 2 SO 4 was increased. These effects appear to be due to the release of silicate from the basalt as well as modest amounts of phosphate in the rock.
