Title: Trivedi Science - Improve Soil Quality for Healthy Plant/Crop Growth

  • Soil is the mixture of minerals, organic matter,
    gases, liquids, and the myriad of organisms. It
    is a medium for plant growth it is a means of
    water storage, supply and purification it is a
    modifier of the atmosphere. Soil is considered to
    be the "skin of the earth" with interfaces
    between the lithosphere, hydrosphere, atmosphere,
    and biosphere.

Types of Soil
  • Laterite Soil
  • Desert Soil
  • Mountain Soil
  • Saline and Alkaline Soil
  • Peaty and Marshy Soil
  • Cohesive Soil
  • Residual Soil
  • Alluvial Soil
  • Marine Soil
  • Aeolian Soil
  • Glacial Soil

Soil Testing
  • In agriculture, a soil test is the analysis of a
    soil sample to determine nutrient and
    contaminated content, composition, and other
    characteristics such as the acidity or pH level.
    A soil test can determine fertility, or the
    expected growth potential of the soil, which
    indicates nutrient deficiencies, potential
    toxicities from excessive fertility and
    inhibitions from the presence of non-essential
    trace minerals. Laboratory tests often check for
    plant nutrients in three categories  Major
    nutrients nitrogen (N), phosphorus (P), and
    potassium (K)  Secondary nutrients sulfur,
    calcium, magnesium  Minor nutrients iron,
    manganese, copper, zinc, boron, molybdenum,

Soil Testing parameters
  • The Squeeze Test
  • The Percolation Test
  • The Worm Test
  • Ph. Test

Soil Erosion
  • Soil erosion is the erosion of soil's upper and
    important layer through air and water. The
    effects of soil erosion go beyond the loss of
    fertile land. It has led to increased pollution
    and sedimentation in streams and rivers, clogging
    these waterways and causing declines in fish and
    other species.

Reasons for Soil Erosion
  • Overgrazing
  • Heavy Water Flow
  • Deforestation

Importance of Plants for Soil!
  • Plants provide protective cover on the land and
    prevent soil erosion for the following reasons.
  • Plants slow down water as it flows over the land
    (runoff) and this allows much of the rain to soak
    into the ground.
  • Plant roots hold the soil in position and prevent
    it from being washed away.
  • Plants break the impact of a raindrop before it
    hits the soil, thus reducing its ability to
  • Plants in wetlands and on the banks of rivers are
    of particular importance as they slow down the
    flow of the water and their roots bind the soil,
    thus preventing erosion.

How to Control SOIL EROSION?
  • The use of contour sloughing and windbreaks.
  • Leaving unplugged grass strips between ploughed
  • Making sure that there are always plants growing
    on the soil, and that the soil is rich in humus
    (decaying plant and animal remains).
  • Avoiding overgrazing and the over-use of crop
  • Allowing indigenous plants to grow along the
    river banks instead of sloughing and planting
    crops right up to the water's edge.
  • Encouraging biological diversity by planting
    several different types of plants together.
  • Conservation of wetlands.
