I would say that a pound of N per month can be a little excessive, though you may be on the right track. Here are some things to consider.....The reasoning years ago was a pound a month, but this was when urea was the common source of N. About half of the N in urea is lost due to volitization. In the case of organics, you may be only getting a half pound as well. Products such as Milorgonite have something similar to a half life. If one pound is applied, the turf will recieve 1/2 lb this year, 1/4 lb next year, 1/8 lb in two years, etc. Kentucky bluegrass should recieve about 3-5 lbs of N per growing season, so I would say you are pushing the turf a little too much. Too much N can lead to outbreaks of some pretty nasty diseases, though you are on the right track of using slow-release organics to prevent diseases. You may want to add iron to your yard, as it helps to provide the dark green color you are looking for. Also, you may have a cultivar of bluegrass that is a lighter green and may not get a deep color. I would suggest keeping the N in the 3-5 lb range (stick with organics if you like), applying iron once a month, and backing off on the water. If you want your plants to grow any roots, make them search for it.
