Crop Performance, Soil Health, and Water Stewardship
CORN
Validation Source:
University of Vermont Extension
Results:
- Yield response: +14.2% vs untreated control
- Yield comparison: +11.4 bu/ac vs a leading organic commercial fertilizer under equal-N conditions
- Water/nutrient stewardship: about 45% less nitrate release
TOMATO
Validation Source:
University of Vermont Extension
Results:
Yield Performance
- +39% vs commercial organic brand
- +61% vs urea
- +93% vs hemp seed meal
CABBAGE
Validation Source:
University of Vermont Extension
Results:
- Yield Performance: ~4% fresh yield advantage
- Nutrient stewardship: 56–68% lower late-season residual soil nitrate
BEETS
Validation Source:
University of Vermont Extension
Results:
- Yield: approximately 25% above hemp seed meal, 21% above soybean meal, 12% above urea, and 9% above a commercial market brand for one NutriHarvest® formulation.
- A second NutriHarvest® formulation delivered yield about 6% above hemp seed meal and 2% above soybean meal.
- Soil findings showed distinct nutrient profiles across treatments, with significant differences in magnesium, calcium, sulfur, iron, and boron.
GREEN BEANS
Validation Source:
University of Vermont Extension
Results:
- Yield: NutriHarvest® formulations delivered green bean yields approximately 13% to 15% above hemp seed meal and 3% to 4% above a commercial market brand.
- Field work also provided a season-long view of soil nitrate patterns and nutrient timing.
- Results suggested strong yield performance can coexist with meaningful differences in nutrient release patterns and soil nutrient status.
LETTUCE
Validation Source:
University of Vermont Extension
Results:
- Trials in greenhouse environment showed significant differences in germination, seedling yellowing, and yield across treatments.
- The 10% treatment stayed close to the control on germination while leading overall on yield and showing lower seedling yellowing than the control.
- Higher amendment rates were less consistent, and the 30% rate showed the weakest establishment and growth.
- Results suggested that adding NutriHarvest at a lower rate may improve lettuce establishment and yield performance, reinforcing that nutrient release timing matters in short-cycle crops.
POTATO & SWEET POTATO
Validation Source: Customer / Grower observation and field story
Results:
Grower Observation
- Positive crop response observed in potato and sweet potato production
- Grower-reported experience supports practical use under real field conditions
- See the linked story for field context and grower comments
STRAWBERRY
Validation Source: Customer / grower story
Results:
- Grower-reported strawberry performance highlighted strong berry production supported by slow-release nutrition.
- This story reinforces NutriHarvest®’s relevance for fruiting crops and seasonal yield-focused production.
SEEDLINGS
Validation Source: Greenhouse seedling work by the GSR Agriscience team
Results:
- Greenhouse seedling work showed distinct early-emergence and sustained-establishment profiles across multiple plant types.
- These results support NutriHarvest®’s value in early-stage propagation and crop establishment.
FLOWERS
Validation Source: Customer / grower story
- NutriHarvest® also highlighted strong blooms, soil health, and water-friendly growing for flower growers and gardeners.
- This supports the brand’s horticulture and garden relevance beyond food crops alone.
WATER / NUTRIENT STEWARDSHIP
Validation Source:
University of Vermont Extension
Results:
- About 45% less nitrate release in corn
- 56–68% lower late-season residual soil nitrate
Manufacturing process: captures up to 90% to 95% of nitrogen and phosphorus from selected residuals to help reduce nutrient runoff.
