Exploring the combination of biochar-amended soil and automated irrigation technology for water regulation and preservation in green infrastructure
• Combination of a carbon sink material such as biochar and automated irrigation technology is proposed for regulating soil water content. • 1-D column tests were conducted to determine optimal biochar content required for regulating water content within the desired range of field capacity. • Water usage is minimal for biochar content between 1% to 3%. This is due to enhancement of soil water retention capacity by biochar. • Excess biochar (5% content) can also lead to development of fungi mold on surface of soil and higher water usage.
