bokashi mudball (also, EM mudballs, beneficial mudballs, genki balls, EM dango): a solid fermented matter (a bokashi ferment) the size of a baseball, made with dirt (or any soil-like material such as clay soil), Activated EM, blackstrap molasses, and bokashi bran. Other ingredients may also be used (such as EM ceramics). While the mudballs are let to ferment in open air (where airflow is recommended to prevent, minimize mold buildup on the mudballs), the outside will quickly dry forming a hard shell leaving the inside to ferment anaerobically.
