USGA Summary Points:Compost and organic fertilizer rates have produced a wide range of SLAN and CO2B test concentrations in fairway creeping bentgrass plots. SLAN and CO2B test concentrations respond linearly to compost and organic fertilizer rates. Fairway creeping bentgrass growth and quality responses are strongly correlated to SLAN and CO2B test concentrations. Trend responses across compost and organic fertilizer rates were generally similar between trafficked and non-trafficked plots for most variables. Binary logistic regression generated curves to estimate the probability that compost and organic fertilizer rate responses would equal or exceed that of the Standard fertilizer treatment. The CO2B test produced better binary logistic regression model fits than the SLAN test. The CO2B and SLAN tests show potential for estimating the mineralization potential of fairway creeping bentgrass soils. The 2021 results suggest that fairway creeping bentgrass soils can be categorized with Solvita tests as to their probability of equaling or exceeding the response of a standard N treatment. The Solvita SLAN and CO2B tests have potential to guide N fertilization of creeping bentgrass fairways.
