How does soil become fertile?
Adding an adequate amount of such nutrients through organic manure and chemical fertilizers can make the soil fertile. Fertile soil will usually contain some organic matter, which increases soil structure, moisture retention, and nutrient retention, as well as a pH of 6 to 7.
How does moisture affect the fertility of the soil?
The water holding capacity of soil make it better and fertile for plants. As minerals needed by plants are dissolved in this water only which plants can use. If there is no water in the soil the plants will not be able to take us these minerals also.

It’s worth mentioning that loamy soils are usually made up of a combination of clay, sand and silt, which gives it a good mix of traits for fertility and productivity Soil order is another way to classify soil types.
