Presentation Transcript

  1. Conservation Agronomy,(definition, Fundamental Consideration, objectives, role and scope)

  2. AGRONOMY • The science which deals with principles and practices of field crop production and soil management. OR • The science of growing plants for creating on farm opportunities for environmental protection and ecosystem management.

  3. CONSERVATION AGRONOMY • The branch of Agronomy that deals with study of conserving soil and water. • The study that shows how to use soil and water resources effectively to attain maximum profit for long time by maintaining soil and water losses to minimum level.

  4. Concepts • Soil & water are the main concerns of this subject • Soil is important because • It provides nutrients to the plants • It provides mechanical support to the plants • Water is important because it is the main requirement of life

  5. Why to Conserve? • Population increasing so the food requirements also increasing. • Soil and water being polluted. • Soil is being depleted by erosion. • Water scarcity increasing.

  6. Objectives • Runoff: • Usually Decreased • Increased in Water Harvesting • Infiltration: • Usually increased • Decreased in Water Harvesting

  7. CONSERVATION SOIL CONSERVATION • It is the act of using land within the limits of economic practiability, according to its capabilities and its needs to keep it permanently productive. WATER CONSERVATION • The act of using water in such a way to attain maximum production for maximum time.

  8. Soil Conservation Methods • Crop Rotation • Avoid erosion • Restorative crops • Green Manuring • Fallowing of land • Mulching • Deep Ploughing

  9. Water Conservation Methods • Lining of canals • Construction of water reservoirs e:g kalabagh dam • Terracing • Contouring • Bund making

  10. ROLE • Water storage for future • Help in increasing yeild • Maximum production per unit area per unit input • Improve the nutrient status in soil • Help to minimize erosion

  11. SCOPE • Govt. is Interested now • A separate Directorate was Founded(Soil & Water Conservation Department) • Head Office in Rawalpindi • Sub Offices in • Jehlum • Khushab • Attok • Mianwali
