Horn Manure is a specially fermented cow manure preparation. It is sprayed towards evening as rough water droplets directly on the soil prior to sowing and planting. It encourages healthy root growth, assists the plant in finding nutrients and mediates the terrestrial forces of life. Under drought situations it encourages deep rooting.
This size is for small gardens as one unit of horn manure (20g) or one unit of horn silica (1g) stirred in 10-15 liters (3gals) of water, is enough for up to  one acre.
