Investor Presentaiton
Detailed meta-analysis of the peer review research has shown that biochar
1. Increases average crop yield by 10-42% with biochar addition,
2. The greatest increases in yield are in low-nutrient P-sorbing acidic soils (common
in the tropics) and in sandy soils in drylands due to increase in nutrient retention
and water holding capacity.
3. It has also shown that biochar can increase P availability by 4.6 times,
4. The effect on yield, plant resistance to disease and soil properties is a function of
dose (Inverted U shape/Biphasic), feedstock and final temperature of biochar
production.
5. Adding small amounts of treated biochar in the rhizosphere every season
will result in a continued increase in soil carbon, plant growth and other
beneficial soil properties and an increase in farmer profitability
