E-Max Release Technology

E-Max release technology is ICL’s leading polymer coating that improves nutrient use efficiency. The controlled release of nutrients is based upon moisture and temperature, offering predictable longevities. Controlled release fertilizers are formulated to match the specific plant needs thanks to the different nutrient release longevities.  

Why Use E-Max Release? 

• Strong durable coating enhances blending and application potential 
• Predictable longevities at different temperatures 
• Release mechanism based on moisture and temperatures 
• Low salt protects against toxicity 
• Reduces nutrient loss; leaching & volatilization  
• Competitive price 

Customized to Meet Crops Needs 

E-Max Release Technology offers a range of longevity and release profiles.  

Based on changing the coating layer thickness we can produce E-Max granules with longevities of up to 5-6 months, making it possible to supply N to different crops with just one base application.  

How does E-Max Release Technology release? 

Influenced by the temperature, the semi-permeable coating regulates the daily release of nutrients. At higher temperatures the release of nutrients will be faster. At lower temperatures it will be slower, in line with the nutritional needs of the plant. 

Typical longevity appearing on the bags is for a scenario with soil temperatures of 21°C. These longevities will change with different temperatures, becoming shorter at higher temperatures and longer at lower temperatures. It is important to take this into consideration when choosing the right product for each situation. 

ICL introduced the first generation of coated fertilizers in 1967 and has been innovating ever since. Contact your local expert to learn more about finding the right E-Max Release Technology CRF for you.
