Biochar and the Depths of Fertility
Why is Terra Preta so fertile? The secret lies in the balance between Soil Organic Matter (SOM) and Fixed Carbon throughout the soil profile. [1][2] When you add Biochar to the deeper layers of your soil, you begin to replicate the conditions that allowed ancient civilizations to cultivate thriving food forests for generations.
Imagine the roots of your crops accessing a treasure trove of minerals and resources, previously locked away in the bedrock. This is the potential that Biochar unlocks. It creates a thriving ecosystem where specialized bacteria and fungi can work their magic, breaking down minerals such as phosphorus, and making them available to your plants. [3] In areas of Terra Preta soils, scientists have discovered insects and micro-organisms completely unique to that environment [4]– testament to the power of this soil-building relationship.
