Suståne 16-4-8 Root Zone Feeder Packs - John Tillman Farm, Northwest Plantations, Elma, Washington

Evaluate plant establishment and growth results under field conditions in Oregon of two Christmas tree species: Noble Fir (Abies procera) and Douglas Fir (Pseudotsuga menziesii) comparing Suståne 4-6-4 all-organic Root Zone Feeder Pack and Suståne 16-4-8 6-month Root Zone Feeder Pack fertilizer formulations (each at 21 grams per seedling) against an untreated control.

Water Dispersible Fertilizer in Tomato Transplant Production - Research: Cornell University. 2017

Objectives

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).

Suståne® 8-4-4 Fertility Trial, Vinca
(Catharanthus roseus ‘Pacifica XP Blush’)

PAT2H Horticultural Consulting Services, Rydal, Georgia, 20098 4 4 vinca trial

 

More than 25% of growers surveyed in 2007 reported managing fertility as the biggest challenge in organic production of ornamental crops, second only to pest management (Burnett and Stack, 2009)1. Therefore, Suståne® 8-4-4, an all natural fertilizer made from aerobically composted turkey litter was evaluated for use on ‘Pacifica XP Blush’ vinca. The trial compared Suståne 8-4-4 (45 day) to two industry-leading control release fertilizers, a 13-13-13(T70) and a 14-14-14(3-4 mo.). Each fertilizer was incorporated at a rate of 0.85 pounds of nitrogen per cubic yard. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat and perlite.

8 4 4 vinca trial

Due to increased environmental awareness and escalating costs of quality control release fertilizers greenhouse production is in need of alternative nutrient sources, preferably derived from sustainable resources. Therefore, Suståne® 8-4-4, an all natural fertilizer made from aerobically composted turkey litter was evaluated for use on ‘Coral White’ vinca. The trial compared Suståne 8-4-4(45 day) to two industry-leading control release fertilizers, a 13-13-13(T70) and a 14-14-14(3-4 mo.). Each fertilizer was incorporated at a rate of 0.85 pounds of nitrogen per cubic yard. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat and perlite.

Suståne 8-4-4 was evaluated for use on "Inca II Orange" marigold. The trial compared Suståne 8-4-4 (45 day) to two industry-leading control release fertilizers, a 13-13-13 (T70) and a 14-14-14 (3-4 mo). Each fertilizer was incorporated at a rate of 0.85 lbs of nitrogen per cubic yard. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat, and perlite.

8 4 4 rudbeckia trial 2009 Timbercrest

More than 25% of growers surveyed in 2007 reported managing fertility as the biggest challenge in organic production of ornamental crops, second only to pest management (Burnett and Stack, 2009)1. Therefore, Suståne® 8-4-4, an all natural fertilizer made from aerobically composted turkey litter was evaluated for use on Rudbeckia Goldsturm. The trial followed plant performance over 135 days and compared Suståne 8-4-4 (45 day) to two industry-leading controlled release fertilizers, a 13-13-13 (T70) and a 14-14-14 (3-4 mo.). Each fertilizer was incorporated at a rate of 0.85 pounds of nitrogen per cubic yard; at 55 days after planting a top dress application equivalent to 0.425 pounds of nitrogen per cubic yard of 8-4-4 was applied to supplement the nutrient source. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat and perlite.

Begonia trial

Suståne 8-4-4 was evaluated for use on "Cocktail Whiskey" begonias. The trial compared Suståne 8-4-4 (45 day) to two industry-leading control release fertilizers, a 13-13-13 (T70) and a 14-14-14 (3-4 mo). Each fertilizer was incorporated at a rate of 0.85 lbs of nitrogen per cubic yard. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat, and perlite.

Trial Performed at The Ohio State University, 2010 ▪ Claudio Pasian, Ph.D.
OSU Geraniums Par 4 vs. 8 4 4 2010

Trial Summary: The results suggest a grower can produce a more vigorous geranium (nearly double shoot dry weight) with no difference in plant quality, flower number, or relative chlorophyll content (SPAD) using 15% less nitrogen when geraniums are fertilized with Suståne 8‐4‐4 compared to Par 4 9‐3‐7.
