Nutrients and water
Build a clear mental model for nutrient solutions, water quality, pH, EC, and responsible measurement.
This section explains how to think about nutrients and water and links to the first source-supported reference and volume-scaling tool.
Water context
Start with the source water, what is known about it, and which measurements can support a decision.
- Source water
- Measurement context
- Change over time
Nutrient-solution concepts
Separate concentration, acidity, formulation, and crop response instead of treating one reading as the whole story.
- Solution concentration
- pH context
- Mixing sequence
Use evidence carefully
Future target ranges will identify their source, units, assumptions, and limits.
- Units and instruments
- Source quality
- Responsible interpretation
