Soil Moisture Monitoring

Tensiometers and Capacitance Probes
Modern agriculture relies on data, not guesses. Precision agriculture uses sensors to optimize scheduling.
- Tensiometers: Measure soil water tension (how hard roots must work to extract water).
- Capacitance Probes: Use electric fields to measure moisture content at various depths.
Use our AI Tutor to explain how to calculate the 'Wilting Point' of clay vs. sandy soil.
