There are manywormswho livein the ground, some of these can represent a real resource for the garden! The most striking example is given byearthworm humus, it is one of the best natural fertilizers available: its effectiveness is comparable to real supplements ofhumusfor the soil. What we commonly callworms, they are animals with an elongated shape and a soft body, since a head, a thorax or a tail is not distinguished, often thewormsthey are not even remotely appreciated!
Thegroundcan be compared to a large multi-layered sandwich: after the cover layer consisting of leaves and organic residues (the layer that protects the soil), there is a layer of decomposition that reaches 5 cm in thickness, it is in this layer that most of the soil biodiversity is enclosed withwormsand life of various kinds. Then there is the humic layer, which is the richest in nutrients, located within 10-15 cm of soil: here are thewormswhich live deeper but above all live there the more superficial roots of plants.
As is clear from the premise, iwormsthey live mainly within the first 15 cm of the soil. Within this depth, in one hectare of wood, we can count 4,000 kg of earthworms to be added to various wormsthat feed on debris of all kinds. THEwormsliving ingroundthey end up shaping the soil as well as nourishing it by producing amino acids, water, carbon dioxide ... If you are wondering "how do worms shape the soil? ", to make you understand this phenomenon, let's talk once again about earthworms.
Thesewormscan have more than 100 segments (by segments, we mean that sort of cylindrical ring that seems to divide the body of the "annelids ",a lump ofwormswith an elongated body and cylindrical shape) and with walking movements they are able to dig tunnels in the ground. If in a hectare of wood the quantity of earthworms amounts to 4000 kg, it goes without saying that many tunnels characterize thegroundon which we walk! These tunnels make the earth porous and less compact, so that water and air can better penetrate the soil.
