BIOCHAR

By
Biochar charcoal used as a soil amendment. It’s made from biomass (waste material from farming and can be used for energy production or raw material for manufacturing chemicals) via pyrolysis (heating of organic materials like in cooking when you cook food, the temperature of the food increase leading to higher molecule vibration). There are benefits of biochar, like for nitrogen and phosphorus, it can attract and retain water and nutrients. It can also retain magnesium and calcium.

Biochar can be a great help for soil because it does not need that much fertilization and it attracts and hold soil nutrients which limits the fertilizer.
