Precision Sensing to Reduce Pollution By Kody Moore
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 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.)
Fish Kills Oxygen sag curve
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? • 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 • 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. • IRROMETER tensiometer- • Provides soil moisture measurements • “prevention of groundwater pollution” • PM-48MB Photosynthesis Monitor- • Monitors CO2 exchange
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 • 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??? • Dedicated to the restoration of the “infamous Ranger”!
