In containerized systems, nutrients applied through water-soluble fertilizers can be lost through leaching — particularly under rainfall or excessive irrigation.

CRFs release nutrients at steady rates, helping:
• Reduce nutrient runoff
• Minimize leaching losses
• Improve overall fertilizer efficiency

Consistent nutrient availability supports uniform growth, stronger root systems, and improved stress tolerance.

Controlled-release fertilizers are coated with materials such as polymers or resins that regulate how quickly nutrients become available.

Instead of releasing nutrients all at once, CRFs provide gradual, sustained delivery to the root zone.
The rate and duration of release are influenced by:
• Temperature
• Moisture
• Coating thickness

This allows CRFs to be formulated with specific longevities to match production cycles and post-production needs.

Once plants leave the greenhouse, nutrient delivery through water-soluble fertilizers typically stops. CRFs continue supplying nutrients during:
• Shipping
• Retail display
• Early landscape establishment

When longevity extends beyond production, plants receive continued nutrition — helping maintain vigor, appearance, and performance. Single-application use also reduces the need for repeated fertilization, simplifying programs for landscape professionals and consumers.
