Crop Application Rates for Suståne 4-2-2:
Incorporating Into Potting Soil Mixes and Other Container Substrates:
Sustane 4-2-2 provides constant release of nutrients when used with container substrates with average temperature of 70oF / 21oC. When determining application rates consider all cultural practices including irrigation, container substrate physical characteristics and growing environment.
Container Mix Application Rates
|Container Mix Rates by Volume|
|lb. per cubic yard||kg per cubic meter|
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 production cycle.
- If mix is stored longer than two weeks, leaching container mix may be required to remove accumulated salts.
- Adjust application rate as needed.
