Suståne® 4-6-4 Organic Granulated Slow Release Nitrogen Fertilizer
Organic Plant Establishment and Soil Builder for Nursery and Greenhouse applications
Suståne 4-6-4 fertilizer is an organic slow-release fertilizer and soil builder ideally suited for plant establishment as vegetation starter for low P soils. Suståne 4-6-4 is specifically formulated to be gentle on plants, making it a go-to fertilizer for spreading with seed and applying to seedlings.
Suståne 4-6-4 works by replenishing the soil with a rich supply of humus (stabilized organic matter) and the essential nutrients required for sound and long-term fertility programs. Suståne 4-6-4 provides a combination of slow-release nutrients and organic substances that improve soil health. Derived from biologically stable compost plus natural potash and feather meal.
While synthetic fertilizers supply plant growth nutrients, they do not supply the organic matter required to maintain quality growth. Using fully composted natural fertilizers increases the levels of beneficial microbial activity, which in turn converts nutrients into plant-available forms.
Benefits of Suståne 4-6-4
- Adds approximately 5% humates by volume, increasing cation exchange and organic matter
- Increases the nutrient and water holding capacity of the soil, strengthening plant tolerance to hot dry conditions
- Promotes healthy root development
- Improves buffering against changes in soil pH
- Increases the soil’s ability to suppress plant pathogens
- Increases soil aggregate stability, porosity, and quality for greater root development and water holding capacity
- Suitable for arid and saline soils
- Dry granulated formulation equates to lower transportation and application costs
- Provides primary and secondary (macro and micro) nutrients necessary for plant growth

- 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 by 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.
