Notes:
Abstract Nitrogen release from individual granules of polyolefin-coated urea (POCU) was studied in order to evaluate a variation in N release. Individual granules were immersed in 10 ml water at 25°C for 7 and 20 d. Individual granules of POCU had different weights and N release rates. An increase in the individual weights of POCU led to a decrease in the N release for both incubation periods. This relationship between the N release and individual weights may be related to the coating thickness.
