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

The Nitrogen Cycle

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)SBNRC 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”!
