What are you seeing?Here we review what surrounds the roots of the plant and the basic quality of the water it receives.
Why it mattersIf a measurement is missing, Yolia tells you why that measurement matters, instead of just making it up.
How to think about itStart with the big ideas: first the type of soil or substrate, and then go into the details of pH and conductivity.
Very simple exampleTwo waters that look equally clear can have completely different amounts of salts — the visual aspect doesn't tell you.
What are you seeing?pH, electrical conductivity (EC), oxygenation, root matrix and water origin together modify the availability and transport of nutrients.
Why it mattersConnecting these signals avoids drawing a conclusion about soil or water from a single isolated piece of data.
How to think about itReview soil/substrate type, pH, conductivity and water source together before interpreting any root symptoms.
Very simple exampleCorrect pH with very high conductivity can still be a real problem for the root, even if the pH alone looks fine.
What are you seeing?The advanced reading adds the physiological mechanisms of root absorption at play, separating measured data from inference.
Why it mattersA soil or irrigation decision must be mechanistically plausible, traceable, and proportional to the quality of the measurement.
How to think about itDistinguish variable, mechanism, interaction, uncertainty, limitation, and what additional measurement would confirm the real cause.
Very simple exampleWithout a direct measurement of pH or conductivity, interpretation of the substrate is limited to an estimate, not a verified data.
