Soil is classified into four types:

Soil Texture The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest.

Layers of Soil

• The O-Horizon.
• The A-Horizon or Topsoil.
• The E-Horizon.
• The B-Horizon or Subsoil.
• The C-Horizon or Saprolite.
• The R-Horizon.

• Tensiometers.

• Sandy soil.
• Silt Soil.
• Clay Soil.
• Loamy Soil.

The simplest soils have three horizons: topsoil (A horizon), subsoil (B horizon), and C horizon.

Soils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base (Figure 31.2. 2). The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base.

The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.

loamy soils

FOUR LAYERS

Soil Types

• Sandy soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients.
• Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients.
• Silt Soil. Silt Soil is a light and moisture retentive soil type with a high fertility rating.
• Peat Soil.
• Chalk Soil.
• Loam Soil.

clay soil

Sand absorbs very little water because its particles are relatively large. The other components of soils such as clay, silt and organic matter are much smaller and absorb much more water. Potting soil is typically very absorbent, this is due to its high organic matter content and very little sand.

Sodium polyacrylate can absorb about 300-800 times its weight. This is the most difference between this kind of polyacrylate and other traditional absorption materials. | High absorbent rate. It only takes several seconds to absorb all the water.

Alluvial soil has the highest productivity with respect to other soils.

Clay soils

Sandy soil

Crops in Black Soils Hence these soils are called as regur and black cotton soils. Other major crops grown on the black soils include wheat, jowar, linseed, virginia tobacco, castor, sunflower and millets. Rice and sugarcane are equally important where irrigation facilities are available.

The aluminum and plastic are made from materials that do not attract water molecules. Also, the aluminum and plastic do not have spaces for the water to move into like felt and paper. Therefore, the aluminum and plastic do not absorb water.

Sorbothane® has been recognized as the highest performance, energy-absorbing material since 1982 and is recognized as the industry standard. Consider Sorbothane’s unique properties: A high tan delta value or damping coefficient. Absorbs more than 94% of shock energy.

cotton

Cotton absorbed – 1 ml. Silk absorbed – 1ml. Nylon absorbed – 2 ml.

Silk is Better for Hair than Cotton Cotton, however, is known for being absorbent. Along with acting as a natural moisturizer, silk is practically free of friction; this means hair gently glides across a silk surface.

Cotton

Silk is generally considered a great insulator, while still breathable, whereas heat easily escapes through an Egyptian cotton sheet. Silk is naturally known for its smooth, luxurious feel, making it extremely comfortable to sleep on. Cotton is also quite light, breathable but slightly coarser than silk.

The truth is cotton is cooler than silk, but there’s a catch about the later fabric. Silk is a natural insulator, it is moderately breathable making heat escape through it and because of its insulating characteristics it will also make you feel warm during the colder months of the year.
