Soil - Moisture


The only system in the world with a bi-directional pump that automatically maintains true field conditions within the lysimeter. Field moisture is measured and transmitted to the control center. If the water is too dry, water is pumped into the lysimeter. If the soil becomes too wet, water is pulled out by the pump so that true field conditions are maintained at all times.

  • A complete small, weighable, tension-controlled lysimeter combined with tensiometers, soil moisture sensors, data logger and optional GPRS modem
  • Field identical water conditions and temperature dynamics
  • Accurate ET
  • Direct measurement of the water balance
  • Depth flexibility
  • Lightning protection
  • Powered by solar panels
  • More economical and easier to install than large lysimeters
