I've found a lot of products that are mined rock or the natural byproducts of mining that can be used as organic soil amendments. There's stuff like trace mineral II and Rare Earth that provide trace minerals, and rock phosphate that obviously provides phosphate, but also seems to provide some trace minerals. You can make a tea with Rare Earth, but the other products need to be mixed in with the soil, and release slowly as the plant needs them.
