1. deposition

The deposition is the process in which the sediments are left by some agent that has been transporting them after that agent has lost its velocity. The deposition consist mostly of sediments, but it can also include rocks and organic matter. It is a process that is very important for the development and fertility of the soils, as it brings in a lot fertile and fine sorted elements to the soil, making it very productive.

2. loess

The loess is a type of soil that forms as a result of the deposition of sediments by the wind, thus it is a soil that is of aeolian origin. This soil is not falling into the category of fertile soils, but instead it is a relatively poor soil on its own. Mostly, the loess is found at places where the winds are the dominant carrying and depositional agent, which are the areas that are arid and semi-arid.

3. biomass

The biomass in the soil comes from the decomposition of the organisms. As an organism dies, the microbes start to decompose it, and with that, the organism is actually returning the nutrients into the environment, thus it is a process of recycling of the nutrients. The plants are the organisms that produce the most biomass for decomposition, with the animals being behind them. As the biomass decomposes, it creates a very fertile horizon of soil, called the O horizon, or organic horizon.

4. clay

The clay is one of the main components of most soils. It is made out of small particles, but it still manages to stop most of the water from moving further deep into the soil, as it has the property to accumulate and stop water. The clay is also not fertile, so the more there is of it, the less fertile a soil it is. It also has bad properties when it comes to different weather conditions, accumulating water and spreading out when there's more water, and gathering and becoming very tight, cracking in the process, when it is warm and dry.

5. wetland

The peatsoil is a type of soil that forms in the temperate, subtropical, and tropical regions, pretty much where wetlands can exist throughout most of the year or all of the year. This type of soil is not a good soil when it comes to its fertile properties. The peatsoil is over-saturated with water, not having nicely sorted horizons, and most of the plants are not able to survive on it because of it.

6. sediments

The water is one of the most important agent that helps in the formation of the soils, as well as their properties. The water manages to erode lot of material, carry it, and when it losses its velocity, it is depositing that material. The two things that are most important from the deposition of the water are the sediments and the nutrients. This puts on fertile layers on the top of the pre-existing soil, making it very fertile and highly productive.

7. washing

There's a common misconception about the soils in the wet environments like the rain forests, that they are actually very fertile, and that mostly comes from the rich vegetation that grows in this kind of places. The really is different though. The soils in the rain forests are not really fertile, and the only thing that manages to support the lush vegetation is the enormous amount of biomass that is decomposing constantly. This fertile, top layer of the soil is actually vulnerable when it come to erosion, as it is loos, so if the vegetation is cleared, or there are larger amounts of rainfall, it is washed away with ease.

8. sandy soil

The sandy soils are soils that form on the basis of quarts. The name of these soils gives them an adequate description, as they are dominated by a top layer of sand. The size and amount of send particles determines in which of the four categories of sandy soil the soil will fall. These types of soil are characterized that they are not capable of retaining water and nutrients in general, as they are able to wash through very easily because of its loos structure.
