Citrus roots are very demanding in oxygen, required for their respiration and the absorption of nutrients and water. Good soil aeration is essential for the good development and production of the plant and to give it greater tolerance against pathogens that can affect the root.
▶ The effects of poor drainage induce the death of the root system in citrus crops, since the poor development of this, which occurs in heavy soils (clay), is also a consequence of the lack of oxygen (root asphyxia).

On the other hand, the accumulation of toxic gases that are formed (sulfites, methanes and carbon dioxide gas), and the higher concentration of elements such as iron, manganese and salts. A good soil for citrus should not offer obstacles that prevent normal root development, at least in the first two meters (compacted areas, rocks, water table).
Among the main characteristics that a soil should have for citrus planting are: aeration, good drainage and effective depth. The physical properties of a soil are considered more important than fertility, because they are more important than fertility.
For example, fertility is considered an important factor because it is difficult to modify while chemical properties are relatively easier and cheaper to correct with the application of fertilizers.
It is important to know the chemical composition of the soil where the citrus orchard is to be installed, as this provides valuable information about its richness and physical composition, which must be evaluated with a key instrument called soil analysis.
