Many garden soils lose humus and biological activity over time. One effective way to improve soil in the long termis by adding Terra Preta.
Through the combination of biochar, organic material, and microorganisms , a highly stable humus is created that improves soil structure, retains water, and makes nutrients available over time.
The ALPARAMA®. Terra-Preta Nutrient Humus is produced on our farm.
It is based on a carefully balanced mixture of:
A key component of Terra Preta is Activated Biochar.
