Title: Field trial of effects of TerraBioGen liquid organic fertilizer on performance of established creeping bentgrass/annual bluegrass putting green turf following a reduced fungicide application regime
Author: Lyons, E.; Jordan, K.; Carey, K.

Abstract: The objective of this research project was to compare the effects of the sponsor’s organic fertilizer products on performance, especially disease tolerance, of established creeping bentgrass/annual bluegrass putting green turf on a sand rootzone with a reduced fungicide program. Assessments on turf performance were done through visual assessments on turf colour, quality, density, and uniformity, as well as through canopy reflectance using normalized-different vegetation index (NDVI). Occurrence of dollar spot disease was also measured through visual assessments, lesion counts, point quadrat counts, and digital image analysis. Other than an effect of fungicide application, no significant differences were found between treatments.
