Agriculture is the backbone of Indian economy because 75% of India’s population depends on the agriculture. Recently Unmanned Aerial Vehicle(UAV) is deployed into agriculture sector for improving the productivity and the Technology based solution will give the more profit margin, Larger area coverage quickly, reducing time and cost, Accurate results and helps to better decision making.

Smart Agri-Drones For Precision Agriculture And Integrated Farming

  • Multi Spectral Imaging and Data Analytics

    • Image processing to compute Vegetation index
    • Normalized Difference Vegetation Index (NDVI)
    • Green NDVI
    • Normalized Green Red Difference Vegetation Index (NGRDVI)
    • Soil Adjusted Vegetation Index (SAVI)
  • Aerial Mapping

    • Digital Terrain Model (DTM)

Drones-Potential Areas of Application

  • Land Use Pattern / Land Cover (LULC) Data

    • Vegetation data with Cadastral mapping
    • Environmental monitoring and planning
  • Crop Insurance Analysis

    • Damage assessment of crops due to Natural Disasters (Flood, Droughts and Cyclones)
  • Irrigation Plan

    • Flow analysis and Watershed Model Creation
    • Rivers and Canal Interlinking
  • Health Monitoring of Crops

    • Cropping Pattern Data and Plant Counts
    • Site-Specific Weed Management
    • Yield Improvement and Estimation
  • Pest Control and Yield Improvement

    • Spraying Pesticides and Crop Nutrients
  • Agriculture Census

    • Soil Fertility Maps and LULC

Problem Identification

  • Man power and time consuming (Slope terrain, dense bushes, muddy land etc.,)
  • Cost and adding feature information’s
  • More than one lakh deaths in every year due to pesticides sprayed by human being
  • Difficult to calculate the damaged area immediately

Advantages of utilizing UAV

  • High spatial resolution data helps to monitor and decision making
  • Inter- crop uncultivated field identification and to create the awareness of intercrop cultivation to the farmers
  • Fractional vegetation covers identification using the various spectral indices
  • Time and cost effective
  • Increase the agriculture and fish productivity by use of UAS – water quality measurement techniques
  • Veracity of information regarding extent of damage for insurance claims and compensation fixation

Water Resource Management

  • pH

    • Used to measure the concentration of Hydrogen
    • Decides the acidic or basic condition of water
    • pH below 7.0 is termed as acidic, above 7.0 is termed as basic and pH equal to 7.0 is neutral
    • Water for irrigation should have a pH between 5.0 and 7.0
  • Dissolved Oxygen (DO)

    • Microscopic bubbles of gaseous oxygen (O2) that are mixed in water and available to aquatic organisms for respiration.
    • Concentrations of DO are too low, it may have
    • Prevent organisms
    • from growing, feeding, or reproducing properly Lead to unhealthy and less biologically diverse communities
  • Electrical conductivity (EC)

    • Estimates the total amount of solids dissolved in water
    • EC values directly proportional to salinity and minerals concentrations in water

     

  • Temperature

    • Water temperature influences several other parameters and can alter the physical and chemical properties of water like pH, density, conductivity and salinity etc.

Ground water recharge/Drainage Interlinking

  • Contours and drainage networks have been used to identify the appropriate location for ground water recharge and drainage interlinking places

Advantages

  • Proper drainage interlinking to avoid the wastage of water in rainy season
  • Reducing flood in rainy season
  • Increase ground water level
