absolutely! It's why I layer in so many different types
Soft rock, greensand, langbenite, oyster meal, etc.
Minerals are awesome for a compost pile, and after the process that hard-to-uptake phosphorus is broken down into a useable form, here, let me get a technical explanation..
Heres a cut and paste from the University of Minnesota and some study they did, i'd link it, but this part is like waaaay down.
so I just copied
The phosphate in fertilizers and manure is initially quite soluble and available. Most phosphate fertilizers have been manufactured by treating rock phosphate (the phosphate-bearing mineral that is mined) with acid to make it more soluble. Manure contains soluble phosphate, organic phosphate, and inorganic phosphate compounds that are quite available. When the fertilizer or manure phosphate comes in contact with the soil, various reactions begin occurring that make the phosphate less soluble and less available. The rates and products of these reactions are dependent on such soil conditions as pH, moisture content, temperature, and the minerals already present in the soil.
As a particle of fertilizer comes in contact with the soil, moisture from the soil will begin dissolving the particle. Dissolving of the fertilizer increases the soluble phosphate in the soil solution around the particle and allows the dissolved phosphate to move a short distance away from the fertilizer particle. Movement is slow but may be increased by rainfall or irrigation water flowing through the soil. As phosphate ions in solution slowly migrate away from the fertilizer particle, most of the phosphate will react with the minerals within the soil. Phosphate ions generally react by adsorbing to soil particles or by combining with elements in the soil such as calcium (Ca), magnesium (Mg), aluminum (Al), and iron (Fe), and forming compounds that are solids. The adsorbed phosphate and the newly formed solids are relatively available to meet crop needs.
Good shit, I think a lot of times new growers don't truly understand that having phosphorus nutrients in your soil isn't the only important thing.
And trying to get all these things present in a typical seven or ten gallon container, with happy ph, and aeration.
