Resin-Coated Urea Evaluation for Turfgrass Fertilization

(...) The most rapid response to fertilization as measured by fresh weight yields and color ratings was produced by urea, followed in order by SCU, RCU-70, and RCU-100. The release rate of RCU-270 was too slow to produce acceptable color ratings through much of the test at both fertilization times. The most uniform response was produced by RCU-100 at both the single-spring and split treatments (...)
