Key Conclusions

Application of H2Flo to tomatoes generated a substantial $170/acre return on investment (ROI) in energy savings from 25% less irrigation, while maintaining, or even increasing, yield.

Objective

To demonstrate that applying H2Flo wetting agent results in a reduction in irrigation volume while maintaining, or increasing, yield.

Farm practiceNo water conservation/surfactants.
3 irrigation programs (100%, 75% and 50% ETo)

 

Volumetric Water Content: Soil volumetric water content (VWC) readings were taken at a depth of 6″ on bed centers, and 6″ from the west edge (50 observations during the season).

  • Plant height (3 weeks after transplanting [WAT])
  • Foliar dry biomass/plant (3 and 15 WAT; 5 plants/plot)
  • Marketable yields (10 and 12 WAT)

Timing:  Spring 2014

Location: Commercial field west central Florida, USA

Crop: Tomato, variety “Charger“, 12 weeks growing season

Soil type:  Central Florida Sands

Measurements: Marketable yields (pounds/acre).

Results

  • A positive $170/acre return on investment (ROI) in energy savings from 25% less irrigation.
  • Yield maintained with 25% water saving, 100,000 ga/acre water saved.
  • Plots treated with H2Flo at the 50% ETo level increased yield by more than the 100% ETo.
