Controlled Release FertilizersPolymer Coated Urea (PCU)
• Fertilizer granule is coated with a homogeneous
layer of polymer.
• Polymer is highly resistant to damage, retaining
its controlled-release character after handling.

POLYON® and DURATION CR® Fertilizers –
Temperature-controlled Diffusion
Within a week of
application, soil
moisture
penetrates the
polymer coating
through osmosis.
Encapsulated
nutrients are
dissolved, but
not released.
Over time the
dissolved nutrients
slowly release
through diffusion, in
response to
temperature and
coating thickness.
After the complete
release of nutrients,
the polymer coating
eventually
decomposes by
microbial activity
into naturally
occurring elements.

• Lower fertilizer rate (~30%) and cost (~20%) (apply less N because it’s more efficient)
• Better broadleaf weed control
• Fewer call-backs
• 20% more lawns covered in Rounds 2 and 4
• Less time cleaning up hardscapes

Fewer Applications –
Efficiencies Gained
• Reduced cost per day of green
• Less time spreading – labor allocation
• Lower total fertilizer use/cost
• Save on freight (delivery)
• Lower fuel use (tractor, utility vehicles)
• Less handling (reduce injury risk, morale)
• Fewer bags for disposal
• Less wear & tear, equip. maintenance
