Sustane Fertilizer

Sustane has been haralded by top organic fertilizer researchers as one of the best choices in natural feeding. The following research was done by the GGNPC in an effort to compare organic fertilizers;

"...nurseries are researching how different organic fertilizers compare, and how tomost effectively apply them. Early experiments indicated that Sustane 4‐6‐4, a slow‐release pelleted organic fertilizer made in Minnesota out of turkey litter, was a good choice.

To best compare them, fertilizer application amounts were calculated to ensure that all contained the same quantity of Nitrogen,the most critical plant nutrient. While most of the fertilizers produced taller plants, Sustane 4‐6‐4 and seabird guano performed the best as measured by the plants’ root to shoot ratios. In other words, they produced plants with relatively large root systems, a desirable quality for native plants that will need to find water and nutrients quickly upon being transplanted to restoration sites. Since Sustane 4‐6‐4 is more local than the seabird guano from Peru, it remained the nurseries’ top choice."
