The values of the chemical elements normally discussed, but the most interesting is the range of organic compounds, their availability to plants and their resistance to setting and washing.
But more important are the microorganisms in the humus of the Earthworm, showing a bacterial count of beneficial aerobic bacteria, actinomycetes and fungi for up to two billion colonies per gram, making it the best life for the inoculum of soil.
In addition to the nutrient content must be understood that the humus of the Earthworm also adds organic substances to plant growth and yield, as humid acids, fulvic, auxins, gibberellins, hormones, amino acids and vitamins.
The influence of humus on fertility is due to different causes, including direct, as a source of elements for plants, humus acts as a store that fixes the elements when these minerals are abundant, and prevents or hinders lixiviation then assigned to the plant gradually.
