Natural Base + Coated Controlled Release Organic Fertilizer
Designed for Professional Nursery, Greenhouse, and Landscape Applications
120 - 150 Day Nutrient Release at 70º F (21º C)
Suståne 16-4-8 was developed as a combination fertilizer to provide nursery stock with a time-released 4-1-2 nutrient package blended with a 50% Suståne humus-rich, premium natural base. Suståne 16-4-8 Nursery Fertilizer is available in both 180-day and 120-day release profiles to meet the needs of your production cycle. Suståne 16-4-8 Nursery Fertilizer is derived from aerobically composted turkey litter, polymer-coated urea, polymer-coated MAP, and polymer-coated potassium nitrate.
Suståne 16-4-8 is perfect for the production of perennials and woody ornamentals. Nursery producers can use Suståne 16-4-8 to grow beautiful Azalea, Holly, Weigelia, Crape Myrtle, Cotoneaster, Boxwood, Spiraea, Salvia, Hibiscus, and Daylily.

Incorporating into Potting Soil Mixes and other Container Substrates:
Suståne 16-4-8 120-day provides a constant release of nutrients for approximately 180-days when used with container substrates with an average temperature of 70oF / 21oC. When determining application rates consider all cultural practices including irrigation, container substrate physical characteristics, and growing environment.

Container Topdressing Application Rates in Grams:
Low Rate: Recommended for use on salt-sensitive species; when concurrent with liquid feed with production systems utilizing low leaching fractions (less than 10%) and when applied to heavy potting substrates (total porosity less than 65%).
Medium Rate: Recommended for use on salt-sensitive species; when concurrent with liquid feed with production systems utilizing low leaching fractions (less than 10%) and when applied to heavy potting substrates (total porosity less than 65%).
High Rate: Recommended for use on heavy feeding species; with production systems utilizing high leaching fractions (greater than 20%); and when applied to light, porous substrates (total porosity greater than 80%).
- These rates are intended as guidelines. Suståne encourages a trial prior to changing any fertilizer program.
- Do not steam sterilize container mix after fertilizer has been incorporated.
- Do not store container mix more than two weeks after incorporating fertilizer. Plant material can be damaged from salt accumulation.
- Monitor electrical conductivity (EC) of container substrate throughout the production cycle.
- If the mix is stored longer than two weeks, leaching container mix may be required to remove accumulated salts.
- Adjust application rate as needed.
