Hence, earthworm humus is the product resulting from the digestive transformation in the form of excreta that this small annelid exerts on the organic matter it consumes, although as an organic fertilizer it can be said to have an excellent value in macro nutrients.
It should also be mentioned the range of organic compounds present in it, its availability in consumption by plants, its resistance to fixation and washing.
According to experts, liquid worm humus has multiple benefits, among these, it increases the biomass of micro organisms present in the soil, stimulates a greater root development, and retains moisture in the soil for a longer period of time
Other benefits of liquid worm humus include increasing chlorophyll production in plants, reducing the electrical conductivity characteristic of saline soils, improving the pH in acid soils, balancing the development of fungi present in the soil, increasing crop production, reducing the activity of suckers such as aphids, acting as an enhancer of the activity of many pesticides and fertilizers on the market, reducing chemical contamination in soils, and being assimilated by the root and through the stomata.
