Anyone else making their own fertilizers?

9. I compost everything

from the kitchen to the kitchen. My neighbor gives me 5 gal buckets of chicken manure that I mix with the compost to heat it up. She also gives me gallon size bags of eggshells which I use to make calcium carbonate, I bought a 3 dollar coffee grinder at a thrift store to make a fine powder of the shells and mix them with 5% white vinegar then dilute with h2o . The particulars for that are on the interwebs.

I've also experimented with wood ash to soften the soil and biochar but haven't used either long enough to evaluate.
