Mar 25, 2022 · What Is Soil? Soil is not just dirt. It’s a mix of minerals, organic materials made of dead and living organisms, air, and water. This mixture supports life by allowing plants to grow, holding and purifying water, and providing a habitat for organisms to live. What Makes One Soil Different From Another?
Feb 17, 2023 · Soil Horizons. The soil is the topmost layer of the earth’s crust consisting of air, water, inorganic minerals (rock, sand, clay, and slit), and organic matter (dead plants and animals). It forms the source of food for plants. It provides shelter for many animals such as insects, centipedes, burrowing animals, microorganisms, and many others.
3 days ago · Topsoil and subsoil are composed of the same basic materials, though not in equal proportions. There are five core ingredients to soil: minerals, water, air, organic materials, and living organisms. It takes thousands of years for all of these components to come together and form the fertile ground that nurtures us.

- Sandy Soil. If your garden soil looks more like a beach, it means you have sandy soil. Try to squeeze the soil into a ball, and the soil runs through your fingers.
- Clay Soil. Clay soils have opposite characteristics to sandy soil in terms of drainage and the size of soil particles. Unlike sand, clay particles are so small, and the texture gets firmer when pressed together.
- Silt Soil. Silty soils have high fertility ratings and are known to have smaller particles than sand. This soil type is light and moisture retentive. It contains smaller particles of the size between clay and sand soil.
- Loam Soil. Loam soil is a common soil type containing a mixture of sand, clay, silt, and humus. As a rule of thumb, the loamy soil in your garden should contain equal mixtures of the three soil types: sand, clay, and silt.
Plants obtain inorganic elements from the soil, which serves as a natural medium for land plants. Soil is the outer loose layer that covers the surface of Earth. Soil quality is a major determinant, along with climate, of plant distribution and growth.
Here are six common soil types for growing plants and crops: 1. Loamy Soil. Loamy soil comprises three soil types — clay, silt and sand — making it ideal for plant growth. Loam is rich, dark soil that can roll up in a firm ball and fall apart easily when touching it.

What is topsoil?
Soil consists of organic matter (about 5%), inorganic mineral matter (40-45% of soil volume), water (about 25%) and air (about 25%). The amount of each of the four major components of soil depends on the amount of vegetation, soil compaction, and water present in the soil.
