Abstract
Organic fertilizers and biostimulants were tested on Grand Valley State University's Meadows Golf Course in Allendale, Michigan. Five greens, four tees, and three fairways were each treated with a different organic fertilizer or biostimulant. Core soil samples were diluted and placed on several selective media. The isolated colonies were counted and identified. Preliminary data suggests that for the agents tested there is no statistically significant difference in the numbers and kinds of bacteria retrieved. This is meaningful because there is a substantial difference in the ease of application and cost between agents used.
