Summary

• Description:

  The PDF document comprises Form 1 Agriculture notes on the topic of Water Supply, Irrigation, and Drainage.

  The topics and sub-topics covered in the document include:

  • Introduction to Water Supply
    • Water is described as a very important natural resource, necessary for both crops and livestock.
    • Various uses of water on the farm are listed, including cleaning equipment, processing farm produce, mixing agro-chemicals, construction, and drinking by livestock and humans.
  • Sources, Collection, and Storage of Water
    • The three major sources of water are identified as surface water (rivers, dams), ground water (springs, boreholes), and rainwater (from rooftops and rock surfaces).
    • Methods for collecting and storing water are detailed, such as dams, weirs, and water tanks.
    • The notes also cover methods for pumping water, including the use of centrifugal and piston pumps, and water conveyance through pipes or canals.
  • Irrigation
    • Irrigation is defined as the artificial application of water to land to supply moisture for crop growth.
    • Reasons for irrigating are explained, such as to supplement rainfall in dry areas, reclaim arid land, and control certain pests like aphids.
    • Different methods of irrigation are described, including surface, sub-surface, overhead (sprinkler), and drip irrigation.
  • Drainage
    • Drainage is defined as the method of removing excess water from water-logged land.
    • The importance of drainage includes increasing soil aeration, raising soil temperature, and increasing soil volume for root exploitation.
    • Methods of drainage are listed, such as using open ditches, underground drain pipes, French drains, cambered beds, and planting trees that absorb a lot of water.
  • Water Pollution
    • This section defines water pollution and identifies agricultural practices that contribute to it, such as the use of inorganic fertilizers, pesticides, and overgrazing leading to soil erosion.
    • Methods for preventing water pollution are outlined, including implementing soil conservation measures, fencing off water sources, and adopting organic farming practices.

  These notes are comprehensive, neat, and printable, making them an excellent resource for students studying the essential role of water management in agriculture. They are also highly suitable for teachers to use for lesson preparation, providing a structured and clear guide to the topic.
