water pollution
Water pollution
  • Fertilizer runoff is a problem in many parts of the country in our rivers and streams.
  • Discharge from factories, refineries, etc.
  • Chicken and hog farm waste
  • Fertilizer leaches through to water tables
eutrophication
Eutrophication
  • Eutrophication is increased nutrient input into water that exceeds the normal amount.
  • The available dissolved oxygen is then used by organisms that break down these nutrients.
  • These organisms lower the amount of dissolved oxygen available to other marine species (fish, aquatic plants, etc.)

point vs non point sources
Point vs. Non-point sources
  • Point source pollution
    • The source of the pollution can be found
  • Non-point source pollution
    • The source of the pollution cannot be found
solution
Solution?
  • Precision sensing could be part of the solution to the fertilizer loss/pollution problem.
    • It has to be accessible to farmers.
      • Easy to use (easier then random soil sampling)
      • The farmer has to benefit (more money)
types of precision sensors
Types of Precision Sensors
  • Weedseeker-
    • Cuts weed control costs by 80%.
    • Reduces environmental impact.
  • Greenseeker-
    • Average profit of $8.00 an acre.
  • Protimeter Grainmaster i-
    • Measures the moisture and temperature of crops.
types of sensors cont
Types of Sensors cont.
  • IRROMETER tensiometer-
    • Provides soil moisture measurements
    • “prevention of groundwater pollution”
  • PM-48MB Photosynthesis Monitor-
    • Monitors CO2 exchange
post sensing
Post Sensing
  • Next something has to be done to interpret this information to the farmer.
    • The SBNRC (Sensor Based Nitrogen Rate Calculator)
      • This turns the Numbers off of the Greenseeker into numbers the farmer can use.
      • Then goes a step further and gives the farmer a fertilizer recommendation.
conclusion
Conclusion
  • Fertilizer pollution is one of many causes of water pollution which affects everybody in the world.
  • The reduction of fertilizer use would benefit the farmer in most cases.
  • Precision sensors can help the farmers make fertilizer, and irrigation rate recommendations.
questions
Questions???
  • Dedicated to the restoration of the “infamous Ranger”!
