Does Mirimichi Green CarbonPro-G really “unlock” nutrients—or could some of the turf response come from nutrients already in the product? In this commentary, we examine the CarbonPro-G marketing claims, product label, and what turf managers should consider when evaluating soil amendments.

Where do wetting agents actually go after they enter the soil? This video explores the 1975 study “Movement of Two Nonionic Surfactants in Wettable and Water-Repellent Soils” by R. H. Miller, N. Valoras, and J. Letey, examining surfactant movement, adsorption, retention, and leaching in soils.

Can surfactants harm turfgrass roots and reduce plant growth? This video examines the science from “Effects of Nonionic Surfactants on Monocots” by R. M. Endo, J. Letey, N. Valoras, and J. F. Osborn (1969), published in Agronomy Journal, exploring what this classic research actually found about wetting agents, surfactant phytotoxicity, root growth, root hairs, shoot growth, and the important differences between surfactant effects in solution and soil.

Can low oxygen in the soil stop turfgrass roots from growing deeper? This video examines the science from “Physical Soil Amendments, Soil Compaction, Irrigation, and Wetting Agents in Turfgrass Management III. Effects on Oxygen Diffusion Rate and Root Growth” by J. Letey, W. C. Morgan, S. J. Richards, and N. Valoras (1966), exploring what this classic turfgrass research actually found about soil oxygen, compaction, irrigation, and root growth.

Can Hydretain reduce irrigation while maintaining healthy turf? We examine the 2026 study by I. Alejandra Sierra Augustinus, J. Bryan Unruh, Kevin Kenworthy, Alex J. Lindsey & Marco Schiavon, “St. Augustinegrass can sustain performance under water and fertilizer restrictions in subtropical environments,” and what the research found about Hydretain, irrigation reduction, and St. Augustinegrass performance.

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.

Is it really time to stop using urea fertilizer? In this Tinfoil Turfgrass, I review the claims made in a popular YouTube video and compare them with peer-reviewed turfgrass research to separate evidence from misinformation. Discover what the science actually says about urea, nitrogen fertilizers, volatilization, and best management practices for healthy turf.
