This study evaluates the effectiveness of a sponsor's fertilizers when added to Kentucky bluegrass in a poor quality rootzone. Data was collected over the colour, strength, turf quality density, uniformity, and resistance to disease, stress, and weeds. 6 treatments were applied to the plots at random. 3 treatments were variations of the sponsor's fertilizer, 1 industry standard and a control plot. The results showed that all fertilized plots had a higher nitrogen content than the unfertilized plot. The fertilized plots had higher chlorophyll indexes and visual colour response than the control. The Corn Plus treatment was the only treatment that fared worse than the control on a few dates, the other treatments were constantly above the control. The fertilizer that performed the best was the compost + NPK treatment.
