Roots Ltd. develops sustainable agriculture technologies aimed at meeting global agriculture needs and overcoming the challenges currently faced in the industry. Its two proprietary technologies can be integrated either standalone or combined for a comprehensive solution for both root zone temperature optimization as well as access to water irrigation.
The root temperature influences all parameters of the plant’s physiology and thus an optimum Root Zone Temperature (RZT) range is essential for a plant’s robust growth, productivity, and quality. The RZT optimization system makes use of the fact that at a depth of few meters, soil maintains a relative stable thermal profile that approximates the mean annual air temperature, and is unaffected by daily or seasonal air temperature fluctuations. Leveraging the principle of Ground Source Heat Exchange (GSHE), Roots installs a closed-loop system of pipes and circulation pump only, with the lower part (heat charging area) dug & placed at depth, and the upper part (heat discharging) in the target crop’s root zone. The result: by heating the root zone during the winter and cooling it during the summer we maintain RZT at a relatively stable and favorable range throughout the year. This technology is capable of increasing crop yield significantly, as results from 7 installations and 15 different crops revealed an increased yield of between 20%-140% depending on the crop concerned. In addition, the technology enables shorter growth cycles, better crop quality, energy savings, greater biomass, planting earlier in the year, and reducing of extreme temperature effects on plants.
Roots further presents Irrigation by Condensation (IBC) technology, a standalone, closed-loop, solar-operated system which irrigates crops by condensing water from the humidity and moisture contained in the air and soil present on the external surface of pipes. Once the system’s water tank is filled, the water is continually cooled below the dew point and the chilled water is circulated in pipes present on the ground’s surface or in the soil at the plants root depth. The humidity that condenses on the pipes is used to irrigate the crops with pure chilled water.
