Clayey soils, structure and characteristics

What are iclayey soilsand how do they recognize each other?
From the fertility of the ground the health of the plants depends and consequently also ours. Agroundrich in mineral salts and organic matter is the key to a good harvest and iclayey soilsthey are a good starting point. There are different types of soil, the main three are: clayey, silty and sandy. Theselandthey are distinguished by their structure which determines all their characteristics.

The clayey soilit is very fertile, it is distinguished to the touch by its plastic consistency and by the fact that it manages to maintain the given shape. Its negative sides are strongly related to the structure: by retaining moisture it presents difficulties in drainage and to improve its structure, it needs a lot of manpower with the addition of compost and organic fertilizers. It is best suited for greenhouse crops as it tends to freeze very easily (again because it is very rich in humidity!). For outdoor cultivation, the use of loamy soil is recommended, perhaps covered with a layer of mulch!

THEclayey soils,due to their structure, they are also defined as "heavy" or "compact". They are called "clayeyā€¯Because over 40% of its composition is given by clay (clay minerals, silica, hydroxides of iron, aluminum and humus). For the domestic garden iclayey soilsare not ideal, as stated, they go well with greenhouse crops but without adequate precautions, the structure ofclayey soilsrequires numerous precautions:
- plowing: to form a layer of disintegration so as to improve the overall porosity of the soil and reduce its degree of compactness. For plowing, the soil moisture must be considered and to avoid the formation of the processing crust, the depth of plowing must be varied every year.
- harrowing, especially in the sowing period
- amendments: it is necessary to add sand, remembering that the limit composition of aclayey soilit is made up of 40% clay, 30% silt and 30% sand.
