In the garden, earthworms work for you.

All lots contain more or less large quantities of earthworms. For the average person, they all look alike, but in reality there are many species quite variable from one another. Depending on the quality of the earth and what is there above, the amount of worms can vary from just a few hundred thousand to several million per hectare. Earthworms are a boon to the garden. They improve your land in several ways. First, they have a mechanical action: * Through their galleries, they loosen the soil and facilitates the penetration of water, and air as well. * Due to their high consumption of decaying vegetation, humus and soil, they digest and expel their feces, they contribute greatly to shake the ground. * Also, as sometimes they go down deep swallow of the earth and live in the open air drop their droppings, they go back nutrients to the surface. They also have a biochemical action on the earth that passes through their bodies. Studies have shown that the feces of earthworms are far richer than the surrounding land: * 5 times more nitrogen-rich * 2 times more calcium-rich * 2.5 times richer in magnesium * 7 times more phosphorus-rich * And, most, 11 times richer in potassium. With that, I hope you see the droppings of earthworms differently! Another thing, as said in the title, earthworms work for you. It has been estimated that about earthworm swallows its own weight of soil per day, yielding 300 g per year. So an area of ​​1 hectare which would contain 300,000 worms, they brew 90 tons of soil per year. Not bad for workers who cost you nothing! Reduced to a 300 m² garden, it's still 2.7 tonnes of earth moved and enriched with nutrients. This is far from negligible, right? So take care of these little creatures, they are worth it. Remember that compost is always rich in worms, worm eggs and baby worms, and so when you put the compost in your garden, you greatly increase the rate of earthworms.
