power seaweed fertilizer is a natural organic fertilizer manufactured by two-phase fermentation using elaborately selected fermentative bacteria. The main raw material used for the production of power is extracts of natural seaweed. The natural bioactive materials in seaweed are maintained in power product by using specific biological techniques. power contains alginic acid, humic acids, nucleotides, vitamins and plant growth regulators (such as auxins, cytokinins and gibberellin) as well as various macroelements and microelements. Those materials can stimulate plants to generate specific biological factors, which may promote plant growth. Many experiments have been conducted and the results indicated that power fertilizer could be highly effectively used on grain crops, vegetables, fruit trees, particularly on cotton, tobacco, mulberry, garden, and tea etc.
