No, it is not true.
Naturally occurring soil is a mixture of non-organic particles (like clay, silt, sand and gravel), organic matter in all stages of decay, and living organisms (like bacteria, fungi and insect larvae).
You can make soil that is entirely made from organic matter, but it will not consist only of decayed plant material.
Even if you start with a pile of dead leaves, by the time it has become soil, it is no longer purely plant material. Decay (apart from mechanical erosion) is only possible through the action of decomposers living off the leaves, dying and eventually becoming part of the soil. The decomposers are fungi or animals, not plants.
The organic matter in soil does not have to come from plants - dead pets work just fine! Then you get soil composed of decayed animal material, plus living and dead microorganisms, fungi and animals, without any plant material.

ViviNo, soil is made of a mixture of organic matter, minerals, water, air, and living organisms in various stages of decomposition. While decomposed plant material contributes to the organic matter in soil, it is not the only component. Minerals are a significant part of soil composition, derived from parent rock material through weathering processes.

What is soil mostly made of?
Soil is mostly made up of mineral particles (such as sand, silt, and clay), organic matter (decayed plant and animal material), water, and air. These components interact to provide plants with essential nutrients, support, and drainage needed for growth.
In soil organic matter is made of?
Soil organic matter is made of decomposed plant and animal material, such as dead leaves, roots, and microorganisms. It plays a crucial role in maintaining soil structure and fertility, as well as promoting soil health and providing nutrients for plants.
Is peat derived from living things?
Yes, peat is derived from partially decomposed plant material that accumulates in waterlogged conditions over long periods of time. This material comes from decaying vegetation such as mosses, grasses, and shrubs.
What is soil parent material?
Soil parent material is the underlying geological material from which soil is formed. It can be organic material, such as decomposed plant matter, or inorganic material, such as rocks or sediments. The characteristics of the parent material influence the properties of the resulting soil.
What is tumbleweed made of?
Tumbleweed is made of dried and dead plant material such as grasses and shrubs. As the plant dries out, it detaches from the root system and is blown by the wind, rolling across the landscape.
