Answer:

What is written in this text is very important because when a crop is made, the land must be evaluated for mineral content, the pH it presents and if it is ideal for the plant to be cultivated, the number of hours of sun and shade that they would give the crop in that area of the land, in addition ... A very important factor is that the plants compete for the land, if the crop has to share the land with another species it is necessary to evaluate if among these species they compete for nutrients and which of the two would be more dominant.

Furthermore, the drainage areas on the ground is a factor that cannot be neglected.

Explanation:

There are in other areas where the land is very prone to pests or certain virulence phenomena that when cultivated, if it is attacked by a pest, it will be destined to be discarded, since today many pesticides are contraindicated and are not well supported either. for some crops.
