  • Automatic Drip Irrigation System
  • Introduction:
    • In India economy is mainly based on agriculture.
    • The continuous extraction of water from earth is reducing the water level.
    • Unplanned use of water results in significant amount of water goes waste.
    • Poor irrigation efficiency of conventional irrigation system reduced the anticipated outcome of investments made towards water resource development
  • Drip Irrigation:
    • 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.
    • Water and nutrients enter the soil from the emitters, moving into the root zone of the plants
  • Drip Irrigation system
  • Field Work:
    • 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.
    • Tank capacity is 1.5 lakhs of litres.
    • Electricity supply is 4-6 hrs daily for agriculture and even less in summer.
    • Normal irrigations requires 1 lakh lit of water for 3 acers
    • 20 min of water supply of 2 days for each plant by drippers.
    • .
    • For an acre the equipment cost is nearly Rs 10,000.
    • There is 1 main line and 7 sub lines.
    • Main line is of 90mm.
    • Sub line is of 60mm.
    • Each tree needs 25-30 liters of water per day in normal times. And 50 liters in yielding season.
    • Water flow rate to tank is 120 liters/min.
    • Water flow rate from tank to field is 420 liters/min.
  • Proposed system:
    • To eliminate the electricity shortage, we use a battery back up which serves best in summer.
    • The water wastage can be reduced upto 60% by this automated system by using sensors.
    • Manual intervention is reduced.
    • The yield will be improved by this system.
  • Problem Statement:
    • Nearly 20% of the farmers are dependent on electric water pumps for irrigation which demands electricity.
    • The increased demand for power in urban areas have further deteriorated the power supply to agriculture sectors .
    • we use battery bank setup to avoid the effects of the unavailability of the electric power during the peak hours.
    • Though the farmer is not availed with electricity, he can run the motor pump and necessary loads with the battery backups.

  • SOIL MOISTURE MONITORING:
    •   Irrigation management is about deciding when to irrigate and how much water to apply.
    • Yields can suffer if irrigation is delayed and available moisture within the root zone of the crop is appreciably reduced.
    • Irrigation efficiency is reduced if water is applied in excess of what the soil can infiltrate or retain.
    • The soil moisture status within irrigated fields is critical information to maximize the irrigation efficiency.
    • Moisture content differs for different kinds of soils.
    • Basic types of soils include.
    • Sandy soil
    • Clay soil
    • Loam soil
  • Sandy soil
  • Sandy Loam Soil
  • Clay Soil
  • Loam Soil
  • Gumbo Soils
  • Sandy Loam/Clay Loam
  • The pros of this venture are:
    •  
      • Intelligent and Efficient management of resources
      • Precise control of operation
      • Accuracy on the parameters
      • Timely action
      • Robust and Reliable
      • Low cost with greater technology
      • Easy going
      • Eco Friendly
