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.

Suståne 16-4-8 was evaluated for use on "Red Prince" weigela. The trial compared Suståne 16-4-8 (180 day) to an industry standard 18-6-12 (8-9 mo) control release fertilizer. Each fertilizer was incorporated at a rate of 1.8 lbs of nitrogen per cubic yard. The potting medium was 100% pine bark.

The Golden Gate National Parks Conservancy (GGNPC) operates six native plant nurseries in the Golden Gate National Recreation Area. These nurseries aim to produce genetically appropriate, healthy, weed and pathogen free plants for habitat restoration efforts in the park while having the smallest possible environmental impact. The nurseries have grown more than 400 native plant species, and they usually produce around 170,000 individual plants each year.

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.

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.

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.

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.

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.

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.
