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).

The objective of this trial was to evaluate plant performance of Japanese Holly when top dressed with Suståne 18-1-8+Fe (90 day) compared to a standard 22-5-6 (4-5 mo.) top dress fertilizer. Mature 3-gallon Japanese Holly shrubs were used for the trial and fertilizer applications were applied at 10.3 g of nitrogen per 3-gallon container. Plant performance was evaluated over 148 days.
