Pictures of Types of Soil

Introduction to pictures of types of soil

Soil is the thin layer on the surface of the Earth on which plants have their roots.

Soil is made up of weathered rock particles, decayed plant material, and animal matter. Soil also contains microbes. Generally formation of soil formation takes long time. Based on the size of particles present soil is and composition of particles soil is classified into various types.

  • Sandy Soil: Sandy Soils have a grainy texture and are formed from weathered rocks such as limestone, granite, quartz, and shale. Aeration of sandy soil is high and water holding capacity is very less due their gritty texture.
  • Silty Soil: Silty soil is one of the most fertile of soils on earth. It is composed of mineral deposits like Quartz and fine organic particles. It is granular like sandy soil but contains more nutrients than sandy soil and has better water holding capacity. Silty soil can withhold more moisture and at times becomes compact. Texture of silty soil is smooth when dry and looks like dark sand.
  • Clay Soil: Clay consists of very fine grained particles which allow very less air spaces. Water holding capacity of clay is high sometimes leads to water logging condition and aeration in clay is minimal. Clay becomes very heavy when it is wet.
  • Loamy Soil: This soil consists of sand, silt and clay in specific composition and is considered to be the perfect soil for cultivation. The texture is grainy and retains water very easily, still the drainage is well.
  • Peaty Soil: Peaty soil is generally formed by the accumulation of dead and decayed organic matter and it contains more organic matter when compared to other. It is usually found in marshy areas.
  • Chalky Soil: This soil is very alkaline in nature and is composed of a large number of stones. Chalky soil is prone to dryness during summers and affects plantation, as the plants would require more amount of water and fertilizers than on any other type of soil.

Depending on the composition of humus, organic matter and the underlying bedrock in the soil they can also be classified as acidic and alkaline types. We can see the different types of soil in the following pictures.
