Suståne® 5-2-4 with Iron is a granulated professional turfgrass and landscape fertilizer.

Description:

Suståne 5-2-4+Fe is the original Suståne formula first created in 1988. As this was the first Suståne product available on the market, it soon became the standard organic evaluated by numerous universities. Michigan State University, Cornell, University of Rhode Island were three of the first research facilities to discover that Suståne 5-2-4+Fe was highly suppressive of common diseases affecting cool season grasses including root Pythium, Necrotic Ring Spot, Red Thread and to a lesser extent various patch diseases. More organic fertilizer studies have been run utilizing Suståne 5-2-4+Fe as the standard against which all other “organics” are compared.


Recommended Use:

Suståne 5-2-4+Fe is the all-purpose turf food and is available in either Medium Grade (lawn and fairway applications) or Fine Grade for putting greens. Suitable for use on all turfgrass types providing quick green up followed by long lasting slow release organic nitrogen. Use where even growth and color is needed for six to eight weeks.

Benefits of Suståne 5-2-4+Fe

  • Provides quick green up followed by six to eight weeks of even color and growth
  • Increases the nutrient and water holding capacity of the soil.
  • Strengthens plants tolerance against hot dry conditions
  • Promotes greater root development.
  • Improves buffering against changes in soil pH
  • Increases the soil’s ability to suppress plant pathogens
  • Increases soil porosity and stability for greater root development and water holding capacity

Always Safe for Plants, People and the Environment

  • Manufactured by Suståne in the USA at an EPA permitted facility.
  • Pathogen and weed free, no blood or bone products. Allowed for export to over 60 countries world wide.
  • Aerobic composting eliminates animal and rodent attraction to application site.
  • Contains naturally occurring beneficial bacteria and fungi that are necessary to begin nutrient life cycle in poor soil.
  • Suståne is fully composted eliminating the need for sterilization, permitting a healthy environment for beneficial microbial populations.

Enhanced Disease Suppresion:

  • Begins with Suståne Natural Based Fertilizers
  • Results of studies conducted over the past 20 years have clearly shown the potential for compost amendments to reduce the severity and incidence of a wide variety of turfgrass diseases.
  • For best results in disease suppression apply either as a topdressing after core aerification, as a late autumn winter cover, mixed as a root zone amendment or better yet use as the standard fertilizer treatment three to four applications per growing season. Studies have shown that applying Suståne 5-2-4 plus Iron results in a significant decrease in many turfgrass diseases.
  • The numbers below represent the percent decrease in severity of turfgrass diseases.

Landscape Maintenance:

Professional landscapers have increasingly turned to Suståne 4-6-4 for use on high maintenance turf and landscaped environments. 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 convert nutrients into plant available forms.
