The trial herein is predicated on the work of Tyler et al. (1993) and was designed to evaluate the effect of Suståne® 16-4-8 (120 day) controlled release fertilizer on plant performance of ‘New Gold’ lantana. More than half of Suståne 16-4-8 is composed of an all natural fertilizer derived from aerobically composted turkey litter. The trial compared Suståne 16-4-8 (120 day) to an industry standard 15-9-12 (8-9 mo.) controlled release fertilizer. Each fertilizer was incorporated at a rate of 1.5 pounds of nitrogen per cubic yard. The potting medium was a 3:1 mix (by volume) of pine bark and peat.

Tyler, et al. (1993)1 reported the addition of aerobically composted turkey litter to container substrate for production of ornamental crops is beneficial to plant performance, improved container substrate nutrient retention and provided adequate nutrients for plant growth, including micronutrients. The trial herein is predicated on the work of Tyler et al. (1993) and was designed to evaluate the effect of Suståne® 16-4-8 (120 day) control release fertilizer on plant performance of ‘Magnus’ echinacea. More than half of Suståne 16-4-8 is composed of an all natural fertilizer derived from aerobically composted turkey litter. The trial compared Suståne 16-4-8 (120 day) to an industry standard 18-6-12 (8-9 mo.) control release fertilizer. Each fertilizer was incorporated at a rate of 1.8 pounds of nitrogen per cubic yard. The potting medium was 100% pine bark.

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® 12-12-12 (90 day), a natural based fertilizer made from aerobically composted turkey litter blend with high quality coated controlled release fertilizer was evaluated for use on ‘Alabama’ Coleus. The trial compared Suståne 12-12-12 (90 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. The potting medium was a 50:40:10 mix (by volume) of pine bark, peat and perlite.
