I plan to fertilize the rye grass in my pond watershed this weekend with an ammonium sulfate/urea blend 32-0-0. Other than my FA going nuts is there any risk to the health of my FHM, CC, CNB and RES? I usually apply 200# to the acre this time of year, but this will be the first time since the ponds were renovated and stocked since I've owned the place.
