A way to manufacture vegetation nutrition soil by using a algae

摘要

PURPOSE: A method for making nutritional earth for plant growth by using algae is provided to simplify the processing steps, reduce the manufacturing cost, obtain various nutritional constituents and recycle the sludge derived from water purification. CONSTITUTION: The method for making nutritional earth for plant growth comprises the steps of: performing the aerobic treatment of algae by injecting air in the form of fine bubbles into water to float the algae on the water surface; crushing the corroded materials obtained from the preceding step into microparticles; mixing soil with the microparticles in an optional ratio; and then fermenting the mixture to provide the nutritional constituents needed for plant growth. In particular, the soil is added in the amount of 5-70% based on the volume of the dried and crushed algae.
