Turfgrass Epistemology
Turfgrass epistemology explorers the question 'How do we know what we know about turfgrass science?'. My name is Travis Shaddox and I am a past assistant professor at the Universities of Florida and Kentucky and I have worked in the golf, lawn care, sport turf, and fertilizer sales industries. I am mostly retired now and use my time to conduct a few experiments related to soil testing in turfgrass systems.Â
The objective of this channel is to provide turfgrass managers and DIYers with evidence-based information to help make their turfgrass experience more fulfilling. Scientific publications can be challenging to understand and it is my goal to interpret these publications in a way that is easy to understand and immediately impactful.
