Once you look at the dynamics of the living world, you better understand why applications are done in a particular manner.
Does this mean that it makes sense to apply N in the winter, because most of it may stabilize in the frozen turf??? But we don't want a fresh supply of N as soon as the plants break dormancy in the Spring...
That is one of the issues of cool-season grasses having the ability to put down roots w/out the waste of topgrowth energy... anhydrous ammonia is fine for corn, but not for turf...
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
