Objective: Compare the effect of Growth Products BioNutrients® 8-0-9 on plant recovery in Native Wildflowers that were treated with de-icing salt.
Method: Randomized, complete block design beds, replicated three times. Trial was initiated using 5x5 (25ft2) native wildflower plots.
The plots were planted in the Summer of 2015, with no maintenance thereafter. Applications were made using a non-pressurized sprinkling can. One foliar application of de-icing salts (125 lbs. / 100-gallons) was applied, on 13-MAY, 2016. The application delivered 20-gallons/1,000 ft2, was an approximation of salt run-off per unit area, commercially applied, to cause salt damage to the wildflower plots. BioNutrients 8-0-9, at a rate of 16-oz/25-gallons, was applied on 20-MAY, 2016, via drench at 25-gallons/1,000 ft2.
Evaluations: Evaluations began on 27-JUN, 2016. The plots were assessed by rating Wildflower quality, tip burn, and overall density of vegetation from a scale of 0-100. Quality ratings were based on density and quality of wildflower plots. Tip burn was assessed by the percentage of wildflower leaf burn that was present. And vegetation ratings were based on the percentage of the plot areas that were covered with any type of vegetation. Additional assessments were taken 26-JUL, 23-AUG and 5-SEP, 2016. Evaluations were made to show the effect of BioNutrients 8-0-9 on salt remediation in the treated wildflower plots as compared to the untreated check.
Results: Wildflower quality and vegetation ratings were increased with the application of BioNutrients® 8-0-9, resulting in higher densities and late season vegetation in the treated wildflower plots. Throughout the trial, the plots treated with 8-0-9, continued to have higher wildflower density, with an average increase of 203.38% quality rating over the untreated control and significantly more vegetation overall, with an average increase of 27.89% in vegetation compared to the untreated control.
Damage to the native wildflower plots was also minimized, tip Burn was significantly reduced with an average of 26.57% less tip burn presence in the plots treated with BioNutrients 8-0-9. Health was restored in less time than the untreated plots with only one application of 8-0-9.
