Soils are composed of minerals, organic matter, and water. The organic matter has only existed for around 3.5 to 3.8 billion years of the Earth's 4.5 billion years.
Plants will grow in soils without organic matter, as in hydroponics, or in processed moon rock, but unless plants get the necessary elements needed to grow, such as magnesium, phosphorus, and calcium, they will not grow or reproduce well, if at all.
Such elements are usually available in soils, to a greater, or lesser extent.

Describe about soils and minerals?
Soils are a mixture of minerals, organic matter, water, and air that support plant growth. They are formed through the weathering of rocks over time. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. They can be found in rocks and soils, and are important for various industrial and agricultural applications.
What minerals are present in desert soil?
Common minerals found in desert soil include quartz, feldspar, calcite, and gypsum. These minerals are resistant to weathering and contribute to the sandy and rocky composition of desert soils. Additionally, desert soils may contain varying amounts of other minerals depending on the specific geographic location.
Minerals move downward through soils in a process called what?
Minerals move downward through soils in a process called leaching. This occurs when water carries the minerals down through the soil layers, eventually reaching the groundwater or being deposited in lower layers of soil.
What are the cohesive and cohesionless soils and how thr are differe from each other?
Cohesive soils contain fine particles that stick together due to electrostatic forces, while cohesionless soils have non-cohesive particles that do not stick together. Cohesive soils exhibit plasticity and can be molded when wet, while cohesionless soils have higher permeability and do not retain shape when dry. Additionally, cohesive soils tend to have higher shear strength compared to cohesionless soils.
What are desert soils?
Desert soils are typically sandy or sandy-loam soils with low organic matter content. They have low moisture retention capacity and are often nutrient-poor. These soils are formed through the weathering of rocks and minerals in arid environments.

What are fertile soils rich in?
Minerals
What mineral group forms by the breakdown and weathering of rock forming silicate minerals and are important constituents of soils?
Clays
Why is volcanic soil a benefit of volcanic eruption?
Volcanic soils are the most fertile soils on Earth. Volcanic rocks are made of minerals that contain a wide variety of elements that are important to plant growth
Do animals need minerals form the soil?
yes, animals need minerals from the soils.
What do minerals have to do with soil?
Soils is made up of small pieces of minerals, rocks and organic material.
How is uranium found?
Analyzing samples of soils and waters, examinations of minerals, radiometric measurements in territory (also air surveillance).
Is every soil type a homogeneous solution?
No, some soils have to be conditioned or have additional minerals added to them. Some crops also remove minerals from the soil so they are allowed to just lie fallow.
What minerals are present in desert soil?
Common minerals found in desert soil include quartz, feldspar, calcite, and gypsum. These minerals are resistant to weathering and contribute to the sandy and rocky composition of desert soils. Additionally, desert soils may contain varying amounts of other minerals depending on the specific geographic location.
Where can beryllium be found naturally?
Important minerals of beryllium: beryl, chrisoberyl, phenakite, bertrandite.

Minerals move downward through soils in a process called leaching. This occurs when water carries the minerals down through the soil layers, eventually reaching the groundwater or being deposited in lower layers of soil.
What are four natural resources in Romania?
Fertile soils, forests, fossil fuels and minerals.
