Experiment 1 (Suståne 12-0-1 Hi-N Water Dispersible Fertilizer)
The objective is to compare performance of tomato transplants fertilized with a once weekly drench in response to Sustane WDF 12-0-1 as compared to another organic alternative nitrogen source, 14-0-0 soluble protein hydrolysate (Ferti Nitro Plus), and a conventional alternative nitrogen source (calcium nitrate, 15.5-0-0). In addition, we wish to determine if 12-0-1 application leads to greater nitrogen use efficiency, i.e. if a lower application rate can be used (150 ppm N vs. 200 ppm N).
Experiment 2 (Suståne 8-2-4 Flourish Water Dispersible Fertilizer))
The objective is to compare the performance of Sustane 8-2-4 WDF to other complete liquid organic fertilizers (Nature’s Source 3-1-1, Drammatic ONE 4-4-1) and a conventional fertilizer (Jack’s 21-5-20).

Objectives
Aronia Rate Optimization, Dr. Brian B McSpadden Gardener, Ph. D, Duane Baumler, Randy Petersburg, Earl Goodman, Joel Goodman - 2017
"Suståne Natural Fertilizers significantly improved aronia berry production (Table 3). Overall berry yields increased by 0.36 to 1.67 lbs. per bush depending on the type and amount of fertilizer applied."
"Just one or two annual applications of Suståne 8-2-4 increased berry yields by 11% or 21%, respectively (P<0.10)."
Suståne Compost Tea Use in Irrigated Vegetables, Dr. Brian B McSpadden Gardener, Ph. D - 2018
"Yield assessments revealed significant yield and profitability increases were provided by Suståne compost teas. Both fertigation materials increased the number and weight of harvested fruit, and this led to greater net returns for both treatments than seen for irrigation alone (UTC). The standard compost tea (CT) provided 4.7% more, and the HiN-enriched compost tea (ECT) provided a 13.4% more marketable yield than irrigation alone. This led to a significant increase in net returns per A for the grower. "
Outdoor Medical Marijuana Trials, Dr. Brian B McSpadden Gardener, Ph. D, Michigan - 2017
"By providing slow release N, balanced nutrition, beneficial microorganisms, and natural humate biostimulants, Suståne’s dry granular fertilizers provide the most cost-effective way to produce organic Cannabis."
Indoor Medical Marijuana Trials, Dr. Brian B McSpadden Gardener, Ph. D, Michigan - 2017
"The lower costs, higher return on investment and reduced effort required to implement the Suståne-based fertility program now make it standard practice for this grower."
Optimizing Industrial Hemp Production, Dr. Brian B McSpadden Gardener, Ph. D and United Hemp Industries, Kentucky - 2017
"Despite suboptimal growing conditions, Suståne Natural Fertilizers produced extraordinary results. Suståne 3-7-4 applications were selected to increase SOM and porosity, as well as provide sufficientnutrition in the otherwise P-deficient soils."
"At harvest, hemp plots receiving Suståne 8-2-4 produced significantly higher yields than the untreated control plots. Hemp receiving the low rate of Suståne had marginally higher stalk yields but marginallylower seed yields than the high rate plots. While both rates were profitable for the grower, the ROI was notably greater for the low rate at this site."
High Application of Suståne 8-2-4 at six weeks.
Dr. Brent Philbrook, Agri-Growth Research Report Summary of Nursery Field Study and Greenhouse Study
Sustane was tested in a field study at Bailey Nursery on soil contaminated with from 20-200 lb. per acre Atrazine. Sorghum Sundgrass was established as a buffer crop before three liners were transplanted. 9 contaminated plots were split into treatments of either activated chatcoal or Sustane.
P. Rajasegaran, Ann Fusorn and Annamalai RajaendranGolden Domes Sdn BhdTaman Melawati, Kuala Lumpur, Malaysia
The objective of the fertilizer comparison trials at KLK Plantation was to evaluate the efficacy of Suståne organic formulations against KLK’s standard chemical fertilizer regime under standard Malaysian oil palm nursery growing conditions..
