Root Zone Temperatue Optimization (RZTO)

Root temperatures influence all parameters of the plant’s physiology and an optimum Root Zone Temperature (RZT) range is essential for a plant’s robust growth, productivity and quality.
The RZTO system is based on the phenomenon that, at a depth of a few meters, soil maintains a relatively stable temperature that approximates the mean annual air temperature and is unaffected by daily or seasonal air temperature fluctuations. The underground temperature is always colder during the summer and hotter during the winter than the top soil temperature. Leveraging the principle of Ground Source Heat Exchange (GSHE), Roots installs a closed-loop system of pipes, where the lower part is installed at the stable temperature depth, and the upper part in the target crop’s root zone. Water flowing through the lower pipes is charged by the soil’s stable temperature. The heated (or cooled) water is pumped through the pipes installed in the root zone, where the heat (or cold) is discharged. The system is able to heat the root zone during the winter and cool it during the summer (by up to 10° Celsius), maintaining the RZT at a relatively stable and favorable range throughout the year. The energy consumption of the GSHE system is for the water circulation pump only.
The result: the system is able to heat the root zone during the winter and cool it during the summer (by up to 10° Celsius), maintaining the RZT at a relatively stable and favorable range throughout the year. The energy consumption of the GSHE system is for the water circulation pump only.
In cases where it is not feasible to dig in order to install the GSHE system, a proprietary, efficient heat pump is used instead. The heat pumps have higher energy consumption compared with GSHE, but they can be programmed to provide a very accurate root zone temperature range as needed.
It is also possible to install a hybrid system that incorporates both GSHE and a heat pump. In this configuration, the heat pump is used only during extreme heat or cold spells and thus the overall energy consumption of the hybrid system is relatively small.
