Knowing the nature of the soil in your garden is important for successful crops.
This allows you to know how to improve it and which species to plant there.
The earth is made up of clay, silt, sand and humus. The quantity of each element in relation to the others determines its nature. It can be clayey, silty or sandy. Its texture, its pH, its ability to retain water or heat up depend on this composition.
To find out, it is possible to have a sample of soil analyzed in the laboratory. Kits on sale in garden centers allow you to get an idea of its pH and fertility. But a simple observation of its color, its texture and the spontaneous flora (weeds) that develop there, may suffice.
