Color changes in the turf, for me,,, indicates whether the grass plants are actively metabolizing the fertilizers any more for growing above ground sections of the plant...

It is well said, IMO, that the plant metabolizes(photosynthesizes) engery as long as the chlorophyll is present along with water, sun, temp and food... this growth is underground so isn't observable from looking at the blades of grass...

The point of this article was to analyse what is actually taking place underground throughout the course of the winter,,, then analyzing the health and vigor going into the following Summer season...
NOTE: The Spring Greenup that everyone looks at,,, has nothing to do with the health and vigor of the plant...
