This study tests the performance of the sponsor’s organic amendment product on root and shoots growth rate when applied to creeping bentgrass in a USGA putting green. Data was collected on the colour, quality, uniformity, density, root system and shoot growth rate, and resistance to disease. 4 trials were conducted involving the sponsor’s product and compared to a trial treated with an industry standard and a controlled trial. The results concluded that under the given conditions, no significant effects were recorded from the sponsor's product in relation to the plot's growth or performance. Some significant effects seen can be attributed to the addition of an NPK fertilizer.
