Production of humic acid and humates

Humic acid is produced from compost by first reacting compost with an alkaline agent to obtain a mixture containing humates. Then, liquid fraction of mixture is separated from solid matter and pH of the liquid fraction separated is adjusted between 1 and 2 with acid. The acidified liquid fraction is...
