Root zone cooling and heating to achieve greater profitability and stability in crop production

About Roots

Roots – Sustainable Agricultural Technologies Ltd. is developing and commercializing disruptive, modular, cutting-edge technologies to address critical problems being faced by agriculture today, including plant climate management and the shortage of water for irrigation.

Roots has developed proprietary know-how and patents to optimize performance, lower installation costs, and reduce energy consumption to a minimumall in order to bring maximum benefit to farmers.

The Company’s two core technologies are:

  • Root Zone Temperature Optimization (RZTO), which significantly increases yield, improves quality, saves energy and mitigates extreme heat and cold stress
  • Irrigation By Condensation (IBC), which provides water for irrigation from moisture in the air and soil

Technology

1Root Zone Temperature 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 result: the system is able to heat the root zone during the winter and cool it during the summer (by up to 10° Celsius). In this way the RZT is maintained at a relatively stable and favorable range throughout the year. The energy consumption of the GSHE 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.

2Irrigation by Condensation (R&D phase)

ROOTS Ltd.’s IBC is a standalone, closed-loop, solar-operated system to irrigate crops by condensing water from moisture/humidity contained in the air/soil on the external surface of pipes. The system’s water tank is filled once. Thereafter the water is continually cooled to below the dew point and the chilled water circulated in pipes placed on the ground surface and/or in the soil at the plant’s average root depth. The humidity that condenses on the pipes is used to irrigate the crops with pure, chilled water.
