Based on this article,,,
and what I've learned over the years, I've arrived at the following conclusion for cool-season grasses... basic principles apply to all grasses , but the timing would be all different...
As the grasses break dormancy early in the Spring they call on their reserves to grow the roots out into the thawing ground... as the ground thaws the microbes become active and begin their mutualistic relationship with the plants' microscopic root hairs...
Since topgrowth is NOT the grasses' priority, the microbes would mine actual minerals from the soil that the plants would like to have to build the strongest and most virile roo tsystem possible... All W/out additional fertilizers and absolutely no root inhibitors...
I imagine that a lot of this early underground growth is over by our 2nd mowing or so... Now is the time I like to add N and Fe so the color brightens up and the robust growth of the entire plant allows new storage
