A Train-the-Trainer Workshop on Agricultural Instrumentation

This SARE-sponsored ag instrumentation workshop focuses on train-the-trainer for six different instruments:

  • Soil Probes (for collecting soil samples) 

  • pH Meters (measures soil water content)

  • Hay Testing Probes (for collecting hay samples) 

  • PAR Meters (measures light transmission, e.g., through greenhouse film) 

  • Tensiometers (measures soil water tension / soil moisture) 

  • Smart Flow Meters (monitors water usage)
