What things make up soil?

Soil is composed of mineral particles (sand, silt, and clay), organic matter (decaying plant and animal material), water, and air. The proportions of these components determine the soil's texture and fertility. Microorganisms, insects, and plant roots also contribute to the composition of soil.


What is a layer of soil at the surface of the ground?

The layer of soil at the surface of the ground is called topsoil. It is the topmost layer of soil which is rich in nutrients and organic matter, making it ideal for plant growth. Topsoil is essential for agriculture and gardening.


What makes up the greatest percentage of the soil?

The greatest percentage of soil is typically made up of mineral particles. These minerals come from the weathering of rocks and minerals, contributing to the physical properties of soil.


What molecule in the ground is nitrogen found when there is no oxygen around?

In the absence of oxygen, nitrogen in the ground is typically found in the form of nitrogen gas (N2). Nitrogen gas makes up about 78% of Earth's atmosphere and can dissolve in soil and groundwater, providing an essential nutrient for plants and microorganisms.


How does finely ground limestone neutralize soil?

Finely ground limestone contains calcium carbonate that reacts with acidic soil to neutralize it. The calcium carbonate in the limestone combines with hydrogen ions in the soil, forming water and carbon dioxide, which raises the soil pH and makes it less acidic. This process helps improve nutrient availability and promotes healthier plant growth.
