Here are 2 steps to charge biochar with urine. Charging biochar is easier than you think… There are many ways to do it, none of them is “wrong”.
The purpose of charging is to fill the nutrient storage capacity of the biochar. This way it will be able to release nutrients once it is in the soil. If you don’t charge it, the biochar will first take up nutrients from your soil and temporarily depleat it.
Charging Biochar – Urine
You can use your human urine or urine of livestock.
1. Put your biochar in a container.
2. Add urine until the biochar starts floating.
3. Keep it uncovered and let it sit for a minimum of 3 days. Charging with liquids is faster because the nutrients can move freely. Keep the mix wet and add water is it dries out.
Apply the biochar to the soil (this is discribed in other posts).
You can always mix your nutrients sources: grass cuttings with compost, manure with urine, compost with manure…
Thanks! Very helpful🙏
I’m glad 😊
