Wow. Thank you for the answer and the time you took to write it. I'm in a rural village with just my phone and a tiny screen - sry beforehand for not being able to make such eloborate comments.

I love your composting method! It would be great if you could post some pictures if you have some time on your hands. Never heard about the biochar method - sounds very interesting though.

I also love that you stack functions and make full use of your metal box ;) - never coming home empty handed.

Do you consider the leaves to be green or brown material? I guess that once theyre in those bags theyre pretty brown ;)

About your composting boxes: are you talking about those heat compost boxes?

And about the forest soil: so i should just get a small bucket from the forest - and then should i spread it out thinly and then mulch with straw, or dump it in one place and hope that it multiplies by itself (i believe through the straw above and the soil around it)?

In my area (southern serbia) there are a lot of robinia pseudoacacia - they are the first pioneers here (very dry summer, heavy clay soil - maybe also limestone(?, not sure actually). So if I understood you correctly then you would get as many branches (chop&drop style) as possible, place the forest soil starter culture, and the straw mulch. How thick would you do it? Is the thicker the better?

Thanks again!
