Organic REV Research Studies

North Dakota State Edible Bean Study

In a 2013 NDSU edible bean trial, REV with fertility generated a 69% higher yield than fertility alone.

Better Microbial Activity

Independent laboratory analysis of REV and ordinary liquid biological products shows that REV has clearly superior biological characteristics.

  • Bacterial activity above expected levels.
  • Bacterial biomass increases over time.
  • Aerobic fungal biomass in normal range.
  • High total bacterial biomass.
  • Biological activity will increase nitrogen efficiency by 25% or more


2018 Organic Tomato Trial - University of Agricultural Sciences

A 2018 field study by the University of Agricultural Sciences in Bangalore found that adding REV to standard organic fertility protocols increased yield and quality of tomatoes dramatically.


Treatment                            Total Yield/kg                            +/- %

Organic Fertilizer                    87.5                               Baseline

Organic Fertilizer + REV     125.0                               +42%


Soybean Field Trials - Winsted, MN 

Chuck Gutzmann farms organically in Winsted, MN. He planted soybeans over corn (no till) and applied 1 quart REV per acre with no fertilizer of any kind.  The results we astounding.  A cost-effective REV application schedule combines with the elimination of all fertility created a dramatic yield increase and positive ROI.


  • Total yield increased from 47 bushels/acre to 58 bushels/acre
  • Plant health was noticeably improved
  • Plants averaged 40 pods each with an average increase of 3+ beans per pod.

Conventional? Organic? In between? REV Works.


REV is organic, but REV works exceptionally well in a conventional fertility program. This is due to the adverse effects that long term acidic fertilizers can have on the soil. REV will immediately provide your seed and soil with extremely high quality usable organic matter. The point of saying "immediately" is important, because other avenues to provide soil with organic matter take time and nutrients to complete the process of decomposition.
