Electrical conductivity of soil as a predictor of plant response

DR. GAYLON S. CAMPBELL

Salt in irrigation water reduces its water potential, making it less available to the plant and causing plant stress. Dr. Gaylon S. Campbell explores how electrical conductivity measurements correlate with crop response and can be used to predict water stress. In this article, learn:

  • Crops suitable for the four salinity classes
  • How much salt will salinize a soil
  • Why little or no salts are lost between the drained upper limit water content and permanent wilting point
  • How to measure electrical conductivity of the soil solution
  • The temperature dependence of electrical conductivity
  • And more…
