Suståne® Enhanced with SumicoatTM Controlled Release Fertilizer

SumicoatTM Controlled Release Fertilizers are polymer-coated controlled release fertilizers initially tested and developed for the rice production markets in several different climates in Japan. Sumicoat products have been used for years to release precisely the right amount of fertilizer to optimize plant growth. For the past several years Suståne has been evaluating different Sumicoat release products blended with Suståne organics to create the optimal nursery and greenhouse fertilizer combinations. Suståne and Sumicoat have been proven through years of research to provide the winning combination that will not under or over release..

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.
