Obtaining the same turf quality and color rating with 1/3 less N is a benefit.
Barry, lets not turn this into a sales pitch. This could simply be showing the turf does not require the level of N being applied by the lesco fert to achieve acceptable results, and has nothing to do with more N getting to the roots.
