• Fertilization with vermicompost and manure also favored growth of microorganisms in the soil.

• The Use of Vermicompost in Sustainable Agriculture 15 Replacement of 25% of the nutrients provided to the corn plants by Vermicompost maintains plant productivity at the same levels than 100% inorganic fertilization.

• The aim is to increase the quality of manure, so as to improve the fertilization of the soil.

• Ocean fertilization is another method proposed for sequestering carbon dioxide in the oceans. Ocean fertilization seeks to stimulate net phytoplankton growth by adding (or pumping) nutrients such as iron into the ocean surface.

• Ocean fertilization attempts to sequester atmospheric carbon dioxide to the ocean interior by adding a limiting nutrient to a selected region of the ocean.

• The goal of iron fertilization at sea is to stimulate phytoplankton growth in order to draw carbon out of the atmosphere and into the ocean. This would be achieved by spreading iron in the sea in those locations where iron is currently in such low concentrations that it limits phytoplankton growth.
