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.
