Enviotin Trials at Kwantlen Polytechnic University

Enviotin can substitute chemical fertilizers

Nutrienvisus Technologies Inc and Kwantlen Polytechnic University completed the collaboration research study (2020-2021). The results provided a scientific evident that Enviotin can improve both soil and plant health. We expected that Enviotin has similar or better efficacy to promote plant health in comparison to the advanced chemical fertilizer – it is a controlled-release fertilizer containing macro and micronutrients and is developed using a polymer-coating technology (called as an advanced chemical fertilizer). Therefore, we use this advanced chemical fertilizer as a control for this trial.

The trial was conducted at the Institute for Sustainable Horticulture Greenhouse, Langley Campus, Kwantlen Polytechnic University, BC, in two native Fraser Valley soils (clay-silt and sandy loam) and horticultural media (Sunshine mix #2) in 1-gallon pots. Three treatments with eight replicates each were applied to each soil type in a complete randomized design for a total of 72 experimental units.

The control treatment using an advanced chemical fertilizer (NPK 15:7:15), was blended with soil or media before transplanting. Enviotin (NPK 5:1:1) was blended similarly before transplanting at 1% by volume (or the ratio 1:100 for Enviotin and soil), subsequent Enviotin treatments consisted of weekly or bi-weekly topdress treatments with Enviotin at a rate of 0.0125% (0.475g/1 gallon pot) per pot.

The results of trials showed that our advanced organic nutrient (Enviotin) can substitute the chemical fertilizer:

  1. High quality plants were observed using both advanced organic nutrients (Enviotin) and advanced chemical fertilizers (control). There is no growth or poorly plant growth without fertilizers/nutrients. However, the additional biweekly Enviotin treatment (0.0125%) in the clay-slit soil resulted in statistically significant more flowers or can be seen in the below picture.


  1. Sandy loam soil promoted more root growth overall, but Enviotin treatments promoted visibly more roots than the control (advanced chemical fertilizer) in sandy loam soil (see below in the below figure). In clay silt and Sunshine mix, there were no differences between root ratings with any of the treatments at 110 days after transplanting.
  1. Trials using Enviotin confirmed that our organic nutrients improve soil microbiome and soil fertility. Enviotin application clearly improved the overall microbial soil population in an industry standard horticultural media (Sunshine mix) as well as in two native BC soil types (Sandy loam and Clay silt) in comparison to the control (advanced chemical fertilizer) and the non-treated soil (no fertilizers). The data is shown in the figure below.


Additionally, next generation sequencing data showed that known beneficial bacterial groups increased in soil growing a flowering annual in the presence of Enviotin.
