Enhanced Efficiency Fertilizers (EEF)
Enhanced efficiency fertilizers (EEF) is a newer term for new formulations that control fertilizer release or alter reactions that lead to nutrient losses. The mechanisms or products include fertilizer additives, physical barriers or different chemical formulations and are similar to earlier versions.
Description
What are Enhanced Efficiency Fertilizers?
Enhanced efficiency fertilizers (EEFs) have been specially developed to provide needed nutrition to turfgrass and ornamental plants. Each product has its own unique characteristics and valued advantages. EEFs provide increased nutrient uptake, while reducing potential losses to the environment through leaching, denitrification, runoff and volatilization. They are also more effective at regulating the release of nitrogen to the turfgrass resulting in more efficient nutrient delivery. By tailoring fertilizer programs that incorporate these advanced technologies, you can optimize nutrient efficiency and minimize nitrogen loss.
At Turf Care Supply, we manufacturer and supply three types of enhanced efficiency fertilizers technologies; controlled-release, slow-release and stabilized nitrogen. Below describes each technology and products we have available.
Controlled-Release Fertilizer Technology
Controlled-Release Fertilizer products are designed to provide a slow, even distribution of nitrogen with extra longevity. Release rate and longevity are controlled by coating thickness and soil temperature. CRF technologies protect turf, improve fertilizer efficiency, reduce leaching and runoff, which results in an eco-responsible choice to ensure consistent plant health.
Polymer Coated Urea (PCU)
Polymer Coated Urea (PCU) consists of urea granules coated with a thin layer polymer, typically a polyurethane. Polymer coatings are extremely durable and resist damage during handling and transport, preserving their controlled-release properties. Through osmotic diffusion, water diffuses through the polymer layer and slowly dissolves the urea core. Over the course of many weeks or many months, urea slowly diffuses through the polymer layer providing an even, controlled distribution of nitrogen over a large portion of the growing season. Once the urea has been depleted, the thin polymer shell is degraded by soil microbes. PCU’s are an environmentally responsible technology due to providing gradual nitrogen release, which reduces leaching and runoff.
