Essential animals for the cycles of carbon (C) and nitrogen (N). Generates excretions that can be used by plants as a highly nutritious natural fertilizer, earthworm or humus excrement contains mainly from 1.5% to 3% of Nitrégeno (N), from 0.5 to 1.5% of Phosphorus and Potassium and from 2.5 to 8.5 % calcium
Commonly known as earthworms, they are a family of oligochaete annelids that are made up of at least 6,000 different types of this species. Their origin is aquatic, therefore they have a cutaneous respiration, they are highly dependent on humidity and they have an important role in different ecosystems because they contribute to the formation of the soil, they actively participate in the cycles of carbon (C) and Nitrogen (N) , also helping to improve the chemical and physical properties of the soil.
The earthworms ingest particles from the soil and digest the organic remains it contains, which increases the production of phosphorus and potassium in the subsoil and this makes the soil conditions much more fertile.
Their excretions become a natural nutrient of a powerful quality that is known as Worm Humus.
Advantages of earthworms
The excrement of earthworms contains biorganic properties that function as a very clean, shredded, light and stable natural fertilizer in prone and imputrescible periods. The chemical properties of earthworm excrement potentiate crop growth by increasing the production of nitrogen, phosphorus and sulfur, as well as inhibiting the growth of fungi and pathogenic bacteria in soils.
In the same way worm humus contributes to the infiltration and retention of water in soils that allows a lower density in heavy soils, in order to improve the union of particles in soils, this also results in the reduction of erosion in the soils.
At temperatures of 0 ° C the worms die because the low temperatures freeze the protoplasm. Therefore, the ideal temperature for its growth is 20 – 25 ° C.
There must be humidity in the earthworm space of 70% because otherwise food ingestion and earthworm landslides are difficult.
