Natural Fertilizer. Bocashi in Central America

The soil’s second chance

One strategy to replenish and maintain soil fertility involves the creation of bocashi. This highly effective and inexpensive natural fertiliser can be made from readily-available materials, including manure, coffee pulp, or rice hulls, together with yeast and molasses. These are then mixed with healthy soil. The yeast feeds on the molasses during a 15-day fermentation and decomposition process, aided by mixing manually twice-a-day. The bocashi mix is then added to crops, and yields either match or improve upon those obtained with chemical fertilisers – at a fraction of the cost.

(Note: This is another example of “cutting the EM hype”, as the method described is a simple farm compost recipe. It involves fermenting to avoid putrefaction. No more, no less. In this case, using yeast.)
