Adding rockdust to a composting system

in homesteading •  7 years ago 

Nice article. I've been researching this a lot recently. Just wondering if you know of any mineral or rockdust sources that are high in iodine? There are some minerals that contain it, and getting it from kelp meal can get expensive. But most rock dust products dont have a very accurate breakdown of the proportions of each mineral.

Keep up the good work.

Good question. To be honest, I’m not sure. I was going to say to use some seaweed solutions or fish amino acid (fish hydrolysate) which you can make yourself.

Alternatively you could breed black soldier fly larvae, feed them fish guts, collect them when they are mature, dry them out and blend them into powder. As bonus you would get some chitin too
