Turfgrass Epistemology

Do wetting agents affect turfgrass growth and soil salinity? This video examines the science from “Physical Soil Amendments, Soil Compaction, Irrigation, and Wetting Agents in Turfgrass Management II. Effects on Top Growth, Salinity, and Minerals in the Tissue” by N. Valoras, W. C. Morgan, and J. Letey (1966), exploring what this classic turfgrass research actually found about wetting agents, irrigation, salinity, and turf growth.

Do wetting agents always help water move into soil? We revisit the classic 1962 study The Effect of Wetting Agents on Infiltration by R. E. Pelishek, J. Osborn, and J. Letey, which found that wetting agents improved infiltration in hydrophobic soils but could have little or even adverse effects in soils that were not strongly water repellent.

Can water really become "wetter"? In this video, we explore the classic paper Soil Wetting Agents by Robert A. Moore (1959) and explain how wetting agents improve water infiltration, root development, and turfgrass performance. Discover why this pioneering research still influences modern turf management today.

Can wetting agents improve water movement in golf course turf? In this video, we explore the classic paper "Turfgrass Improvement with a New Water" by Robert A. Moore (1957) and examine how wetting agents help water penetrate the soil, reduce localized dry spots, and promote healthier turfgrass. Discover why this pioneering research continues to influence modern golf course management and turfgrass science.

Did your brain make your decision before you became aware of it? In this video, we explore the groundbreaking neuroscience study that found brain activity can predict a person's choice seconds before conscious awareness, and what it means for free will.

Did Benjamin Libet's famous 1983 experiment prove that your brain decides before you do? In this episode, we examine Libet, Gleason, Wright, & Pearl (1983), "Time of Conscious Intention to Act in Relation to Onset of Cerebral Activity (Readiness-Potential): The Unconscious Initiation of a Freely Voluntary Act." We'll explain the readiness potential, what the study actually found, common misconceptions, and what it does—and does not—tell us about free will, consciousness, and human decision-making.

In this episode of Turfgrass Epistemology, we examine Stanley Milgram's classic paper, Behavioral Study of Obedience (1963), and explore how authority influences our beliefs and decisions. Why do turf managers, consultants, and consumers often accept claims because a professor, university, or industry expert said them? Learn how the logical fallacy of Appeal to Authority can lead us to substitute credentials for evidence—and why scientific claims should be evaluated by data, not status.
Paper Discussed:Milgram, S. (1963). Behavioral Study of Obedience. Journal of Abnormal and Social Psychology, 67, 371–378.
