A highly effective biological fertilizer (bio-fertilizer) can be produced cheaply in countries that have a source of a suitable type of zeolitic rock (tuff). Such rocks occur worldwide in areas of past or current volcanism. In the event of explosive volcanic activity huge volumes of silicic glass and other debris are projected into the atmosphere.
