With DURATION CR® fertilizers from Agrium Advanced Technologies, nitrogen (N) is released gradually throughout the plant’s growth cycle, resulting in precise, predictable feeding that lasts for months. Available in four longevities with various release rates, DURATION CR will take the worry out of maintaining healthy turf, ornamentals and specialty crops while giving you the exceptional performance you demand. All of our DURATION CR products have been extensively tested in field trials for both turf and agricultural applications and consistently stand out from the competition. Plus, laboratory testing has proven that DURATION CR can easily withstand normal handling and abrasions.
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. 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.
