CHARACTERISTICS OF THE TERRAIN
The radicular part or roots exert several important functions for the plant such as fixation, absorption and energy reserve. The quality and typology of the substrate where we plant the plants is an essential factor to ensure a good functioning of the circulatory system as well as an optimal ornamental aspect. Because of that it is necessary to know, before planting, the following soil characteristics:
The texture. Indicates the relative content of different sized particles, such as sand, silt and clay, in the soil. Depending on the percentage of sizes obtained from particles, we will have different soil types. The texture has to do with how easy can the soil be worked, the amount of water and air that it retains and the speed with which the water penetrates the soil and passes through it.
The structure. It is composed of silt, clay and sand particles, and the closer they are, the greater the quality of the soil. This directly affects the aeration of the land, as well as the moisture retention and water circulation.
The ph. We have all heard about alkalinity (value of the substrate from 7 to 14) or acidity (value between 1 to 6) and neutral value (7). The disposition of the macronutrients and micronutrients for the ph plant that we have.
In general, the pH of normal soil in humid zones is from 5 to 7, while for arid and calcareous zones from 7 to 8.5. Any imbalance of the pH must be rectified to guarantee a good development of the plant.
