Physical properties of Soil of plants to maintain their growth

  • Soil is a medium which provides support, nutrients and oxygen to the plants.
  • Soils keep water stored and supply slowly to plants to maintain their growth.
  • Soils also provide the necessary porosity which is essential for the growth of the plant.
  • Large depths of soil do not carry any importance for an Agronomist.
  • He is mainly concerned with the upper crust of the soil, which is primarily used for growing crops.
  • This upper crest retains water and furnishes it for plant growth.
  • The water retained in the upper crust is also termed as the belt of soil water.
  • The depth of the belt of soil, water depends upon, the type of soil and vegetation.
  • The depth of this belt may extend from a meter to several meters below the surface.
  • An Upper layer of soil contains, air, minerals, free carbonates besides moisture.
  • This layer may also contain the remains of plants and animals at various stages of decomposition.
  • Bacteria, fungi, protozoa, worms and insects etc.
  • Are the forms of plant and animal life.
  • All the soils are the resultant of the disintegration of rocks.
  • The resulting soils may have the same mineral composition as that of parent rock or different because of the changes brought about by water,
  • Carbon dioxide and organic materials.
  • The particle size of the soil may vary from very fine clay particle to as large as a boulder size.
  • Physical properties as given above affect the fertility of the soil and growth of the plants.
  • The supply of food to the plant is also related to the physical properties of the soil.
  • The most important physical properties of the soil, which markedly affect the growth of the plant are soil texture and soil structure.
  • According to grain size, the soils may be classified as clay, sand and silt.
  • Agriculture classified various soils with the help of Triangular Texture Diagram shown in Fig.

  • All the soils classified by this method contain varying percentages of clay, sand and silt.
  • If the percentages of clay, sand and silt for a particular soil are given it can be easily classified using this diagram.
  • Soil structure refers to the arrangement of the soil particles.
  • Soil structure depends upon shape, composition and electrical properties of soil particles.
  • There are so many other parameters which also affect the soil structure.
