How DURATION CR Works:
Understanding polymer coating technology
DURATION CR offers polymer-coated urea with 43 to 44% Nitrogen, produced by an advanced generation polymer-coating technology that delivers a predictable release of nutrients. The key to the steady release is the application of a micro-thin membrane that completely coats the Nitrogen fertilizer.
DURATION works through temperature-controlled diffusion.
This means Nitrogen is released gradually throughout the plant's growth cycle, resulting in precise, predictable feeding that lasts for months. Water passes through the polymer membrane, dissolving the nutrients inside. The pressure created releases the nutrients through the polymer membrane at a controlled rate, ensuring that only the prescribed supply of nutrient is received. Only temperature influences the release rate so you don't have to worry about microbial activity or excessive moisture.
All of our DURATION CR products have been extensively tested in field trials for both turf and agricultural applications and consistently stand out amongst the competition. Plus, laboratory testing has proven that DURATION CR can easily withstand normal handling and abrasions.
