Host Mary Lucero continues the discussion begun in episode 6 by expanding on how to interpret the values you might find on a soil test. She includes:

  • the meaning of CEC (Cation Exchange Capacity), and values you should strive for
  • How to raise a low CEC value.
  • how much organic matter (abbreviated as OM, or SOM) a soil needs to sustain biological properties that help your plants grow.
  • what the Base Saturation Percent tells you.
  • the rationale for professional soil laboratory analysis.  
  • what macronutrients and micronutrients your plants need to survive
  • why trace elements that are not considered nutrients might have value to your plant
  • how to ensure that you are adding safe levels of unmeasured trace elements.
