  1. 1. Automatic Drip Irrigation System
  2. 2. Introduction: <ul><li>In India economy is mainly based on agriculture. </li></ul><ul><li>The continuous extraction of water from earth is reducing the water level. </li></ul><ul><li>Unplanned use of water results in significant amount of water goes waste. </li></ul><ul><li>Poor irrigation efficiency of conventional irrigation system reduced the anticipated outcome of investments made towards water resource development </li></ul>
  3. 3. Drip Irrigation: <ul><li>Drip irrigation system delivers water to the crop using a network of mainlines, sub-mains and lateral lines with emission points spaced along their lengths. </li></ul><ul><li>Water and nutrients enter the soil from the emitters, moving into the root zone of the plants </li></ul>
  4. 4. Drip Irrigation system
  5. 5. Field Work: <ul><li>Surveyed area is 30 Acres and they are using 60,000 ltrs of water daily for drip which is reduced from 1 lakh litres by normal irrigation methods. </li></ul><ul><li>Tank capacity is 1.5 lakhs of litres. </li></ul>
  6. 6. <ul><li>Electricity supply is 4-6 hrs daily for agriculture and even less in summer. </li></ul><ul><li>Normal irrigations requires 1 lakh lit of water for 3 acers </li></ul><ul><li>20 min of water supply of 2 days for each plant by drippers. </li></ul><ul><li>. </li></ul>
  7. 7. <ul><li>For an acre the equipment cost is nearly Rs 10,000. </li></ul><ul><li>There is 1 main line and 7 sub lines. </li></ul><ul><li>Main line is of 90mm. </li></ul><ul><li>Sub line is of 60mm. </li></ul>
  8. 8. <ul><li>Each tree needs 25-30 liters of water per day in normal times. And 50 liters in yielding season. </li></ul><ul><li>Water flow rate to tank is 120 liters/min. </li></ul><ul><li>Water flow rate from tank to field is 420 liters/min. </li></ul>
  9. 9. Proposed system: <ul><li>To eliminate the electricity shortage, we use a battery back up which serves best in summer. </li></ul><ul><li>The water wastage can be reduced upto 60% by this automated system by using sensors. </li></ul><ul><li>Manual intervention is reduced. </li></ul><ul><li>The yield will be improved by this system. </li></ul>
  10. 10. Problem Statement: <ul><li>Nearly 20% of the farmers are dependent on electric water pumps for irrigation which demands electricity. </li></ul><ul><li>The increased demand for power in urban areas have further deteriorated the power supply to agriculture sectors . </li></ul><ul><li>we use battery bank setup to avoid the effects of the unavailability of the electric power during the peak hours. </li></ul><ul><li>Though the farmer is not availed with electricity, he can run the motor pump and necessary loads with the battery backups. </li></ul>
  11. 11. Overview of implementation
  12. 12. Functional Diagram
  13. 13. Sensor
  14. 14. Relay Circuit
  15. 15. Total setup
  16. 16. LCD Display
  17. 17. Analog to Digital Conversion
  18. 19. sensor
  19. 20. SOIL MOISTURE MONITORING: <ul><li>  Irrigation management is about deciding when to irrigate and how much water to apply. </li></ul><ul><li>Yields can suffer if irrigation is delayed and available moisture within the root zone of the crop is appreciably reduced. </li></ul><ul><li>Irrigation efficiency is reduced if water is applied in excess of what the soil can infiltrate or retain. </li></ul>
  20. 21. <ul><li>The soil moisture status within irrigated fields is critical information to maximize the irrigation efficiency. </li></ul><ul><li>Moisture content differs for different kinds of soils. </li></ul><ul><li>Basic types of soils include. </li></ul><ul><li>Sandy soil </li></ul><ul><li>Clay soil </li></ul><ul><li>Loam soil </li></ul>
  21. 22. Sandy soil
  22. 23. Sandy Loam Soil
  23. 24. Clay Soil
  24. 25. Loam Soil
  25. 26. Gumbo Soils
  26. 27. Sandy Loam/Clay Loam
  27. 28. The pros of this venture are: <ul><li>  </li></ul><ul><ul><li>Intelligent and Efficient management of resources </li></ul></ul><ul><ul><li>Precise control of operation </li></ul></ul><ul><ul><li>Accuracy on the parameters </li></ul></ul><ul><ul><li>Timely action </li></ul></ul><ul><ul><li>Robust and Reliable </li></ul></ul><ul><ul><li>Low cost with greater technology </li></ul></ul><ul><ul><li>Easy going </li></ul></ul><ul><ul><li>Eco Friendly </li></ul></ul>
