So far this is what I think organic soil means. The soils are chemically fetilized and ammonia and other synthetics are harming the soil. Organic soil is chemical-free, not harming the soil nor the environment.
A soil organism is any living thing that can be found in soil. That includes animals such as earthworms, fungi that have a mutualistic relationship with plants, and a huge variety of bacteria. Soil organisms are important because they return nutrients to the soil by decomposing dead organic matter and organic waste. Some also perform nitrogen fixation, which is a process of making nitrogen into ammonia so that it can be turned into amino acids, the building blocks of all organisms.
Worms eat the dirt and then poop out the soil. Worms eat the dirt and then poop out the soil.
organic soil is the soil that you can plant fruits and veggies in which could also be top soil...
subsoil
the layer the contain the richest material is the top soil :)
The first layer is Litter, the third is Humus, so the second layer would be Duff.
Soil comes in many layers. Commonly, the third layer is the largest part of the soil structure. This third layer can range from clay to sand. Often the Organic matter layer isn't as deep as the third layer.
no answer 2. Well, soil is the organic layer in which plants can grow. The deserts are generally deficient in this, so no plants. Soil can be destroyed by desertification.
Organic layers are part of the soil.
The organic level which is the uppermost level of the soil.
There are four layers and the four layers are top layer called the organic layer, Upper soil layer, middle soil layer, and the last one is lowest layer.

subsoil
the crust
A is the layer of the soil profile in which most organic material is found.Specifically, there are five layers in the soil profile. The first, A layer of organic matter claims the first two inches and contains plant debris. The second, A layer of surface soil comprises the next ten inches down. Below it will be found the third, B layer of subsoil containing aluminum, clay, iron and organic compounds and going down 30 inches; the fourth, C layer of parent rock going down 48 inches; and the fifth, final, R layer of bedrock.
The first layer is Litter, the third is Humus, so the second layer would be Duff.
there is the organic layer which is the top most layer and its about 8cm deep
Humus is located in the top layer of soil. It is a type of organic soil matter and aids in nutrition retention in the soil.
Topsoil.
It's the layer of organic matter in soil. The organic matter largely is built up by the death and decay of organisms that live in soil. Some such organisms include bacteria, beetles, earthworms, and moles.
