Investigating aeroponics, soil, and soil amended with biochar for growing kale: A comparative study

As the global population is predicted to increase, the horticultural produce required to feed them is expected to as well. Growing with unconventional methods such as aeroponics and biochar-amended soil could offer valuable insights into successful food production amidst increasing environmental pressures and decreasing land availability. Aeroponics have been shown to require less water for yield than traditional soil growing. Biochar, a charred biomass used as a soil amendment, has been shown to have greater water absorption and therefore produce greater yield using less water than unamended soil
