GPR 28-0-0, Professional Strength, Enhanced Efficiency
Fertilizer with 72% Slow Release Nitrogen
Green Prairie Ranch 28-0-0 fertilizer can be used on crops
(vegetable and non-vegetable), turf and grasses, trees,
flowers, vines and ornamentals. It can be applied to all soil
types and pH ranges, to all transplant solutions, dips, and to
all watering solutions.
Green Prairie Ranch 28-0-0 Fertilizer is a liquid nitrogen
formulation with 72% slow-release nitrogen. The
slow-release properties keep high quality nitrogen available
to the plant longer, helping sustain growth over the long
term without the surges that can adversely affect plant
health and quality. The nitrogen is released to the plant over
a period of 35 days on the leaf surface and up to ten weeks
in the soil through the combined effects of heat, hydrolysis,
microbial activity and UV radiation.
