Why is Water Quality Important?
    • Water is an important commodity in the American culture. The 
     USDA estimates that agriculture accounts for approximately 80 
     percent of the nation's water use. In agriculture, water is used to 
     grow fruits, vegetables, crops and raise livestock. Even further 
     though, water in agriculture is used for irrigation, the application of 
     pesticides and fertilizers. In Kansas 29% of corn acres are irrigated. 
    • Maintaining good water quality is something farmers strive for to 
     help maintain a healthy ecosystem and to preserve the water that 
     we drink. Farmers practice proper agriculture management to meet 
     domestic water quality standards. Cooperation between agriculture 
     and domestic water users is necessary to provide adequate water 
     quality for both parties.
  Why is Water Quality Important?
    • In this lab students will test water quality from difference sources of 
     water.  
    • This lab is best suited to be delivered right after the soil erosion lab.  
    • Preventing soil erosion is the number one way that Kansas farmers 
     protect from fertilizers and pesticides getting into the water supply.
    •  Farmers are not the only ones who impact water quality in our 
     communities.  Consumers, business and industries can also impact 
     water quality. Golf courses, lawns, parks could all apply fertilizer and 
     pesticides, and all have an impact on water quality. 
    • This lab is designed to get students thinking about how different 
     segments of the communities can work together to improve water 
     quality
  Why is Water Quality Important?
    • Farmers and ranchers work hard to make sure they have a successful 
     crop by reducing potential pollutants by decreasing the availability of:
    • soil to become sediment, primarily through the use of agronomic 
     practices such as cover crops, residue management, and rotations that 
     include close-grown crops;
    • nutrients for transport, by accounting for all nutrients available, 
     regardless of source, method of incorporation, and application rate and 
     timing;
    • pesticides through integrated pest management, including crop 
     rotations, cultivation, biological pest control, scouting, and selecting 
     pesticides that are more environmentally friendly, as well as through 
     reducing the use of pesticides in their operations.
  What are we looking for?
   • For this lab we will testing water supplies from various 
    locations looking for key deficiencies or overabundance 
    for Potassium, Phosphorus, Nitrogen, pH, Total Dissolved 
    Solids and Electrical Conductivity.  
  What are we looking for?
   • Electrical Conductivity (EC) will show the presence of 
    salts in the water.  The higher the salt content, the 
    higher the conductivity reading.  An elevated 
    conductivity test can damage growth due to nutrient 
    deficiencies and lower water uptake by the crop
