The Terra Preta Project, Step 3 and 4


STEP 3:
Once the piggies have done their magic, the earth is mixed with our magic tropical compost mix, and covered with mulch. If using regular compost or organic fetilizer, then charcoal must be added and inoculated with microbial broth. All of this will be discussed later.

STEP 4:
When the soil has rested / incubated a little bit, the next step is to plant green manure. My preference is beans. These beans are then cut just before flowering. The plant is left on the soil and eventualy incorporated.

This step can be repeated as many times as deemed necesary, and depending on the organic composition of the soil. If the soil lacks most topsoil or organic portion of soil this process may take a few years. In my experience if the compost is good, the soil reacts pretty quickly although it will take years before it will become ideal.
