WATER PEARLS - CONSERVATION OF WATER FOR RESILIENT AGRICULTURE BY ELIMINATING EVAPORATION AND HARVESTING CONDENSATION. RHST Industries patented the use of an organic superhydrophobic, inert and re-usable water pearl which is ushering the new age of farming with its proven applications in the soil-based, hydroponics and greenhouse farming industries. Water pearls prevents evaporation of water maximizing nutrient use efficiency, reduces the formation of bacteria, fungus, and weeds; along with the use of herbicides all farming environments. No additional training is required to use it. Other benefits include: ●For soil-based farming: -Reduces water consumption by 50% for current methods -Increases plant yield by 30% without the use of additional fertilizers -Food produced can be certified organic -Requires no maintenance or upkeep for up to 50 years ●For hydroponic greenhouse farming: -Suppression of evaporation, can be used for propagation media and substrate

From Canada
Maturity stage Small scale commercialization
Looking For Network, New clients, Visibility, Funding, Partners, Credibility

The environmental benefits

  • In arid deserts, in plantations,1 kg waterpearls will conserve up to 5000 L of water annually for up to 50 years and reduce the risk of salt intrusion
  • In tree nursery operations, seedling growth will be accelerated by 40% generating savings in inputs and increasing turnover, and during transportation to the site, no watering will be required for up to 2 weeks, ensuring higher survival rates
  • There is no energy input required for the functionality of the solution, It is based on the 2nd law of physics
  • Up to 50% less water footprint in agriculture with higher yields (20% - 30%). CO2 emission reductions of 30% for reduced water conveyance
  • It will eliminate the need for deforestation estimated at 26% for arable land to cope with the increasing demand for food
  • The afforestation of deserts and degraded land will be possible as it encourages soil health by maintaining soil moisture, prevents salt intrusion, and insulates the soil from the heat and deflects the solar radiation from the soil surface

The Financial benefits

  • ROI varies between 3-10 years depending on the crop, market conditions, climate change, value of water
  • For comparison to desalinated water supply, the ROI is less than 3 years, in hot arid countries which supply desalinated freshwater to agriculture
  • To transform the farm into an organic grower will increase revenue by 15-25% and contribute to being a resilient farming operation asset
