Ice Melting Points and Temperature

Cornell Clippings Podcast ·

2026/02/11

How much ice can a pound of salt really melt? In this episode, Frank Rossi and Dan Schied, director of Cornell University Grounds Department, break down the "pounds of ice melted per pound of salt" chart and explain how temperature dramatically changes performance. Sodium chloride loses nearly two-thirds of its effectiveness at 5°F and fluctuates sharply around the freezing point. Find the chart on our website!

2026/02/11

Salt may be just another input for grounds crews — but it's often one of the biggest winter expenses. In this episode, we explore how snow and deicing materials impact turf along sidewalks and managed landscapes. We break down soil compaction, salt injury, rising soil electrical conductivity (EC), and what it means for spring recovery. The team also discusses treated salts, including molasses and magnesium chloride blends, that reduce bounce, work at lower temperatures, and can cut sodium chloride

Pesticides and Transparency: The Origins of the EIQ

Cornell Clippings Podcast ·

2025/09/10

What does it really mean when we talk about the “impact” of pesticides? In this episode, we explore the origin and purpose of the Environmental Impact Quotient (EIQ)—a tool designed to translate pesticide use into measurable environmental impact. Frank Rossi reflects on his early work with the EIQ, stemming from the apple industry and later extending into turfgrass, where it became a way to demonstrate the thoughtful, environmentally aware decisions turf managers make every day. He also revisits his

The Poa to Bentgrass Transition in New York

Cornell Clippings Podcast ·

2025/06/25

Retired golf course superintendent Rick Slattery, formerly of Locust Hill, discusses his spring approach to promoting creeping bentgrass growth over Poa annua. He explains how holding off on spring irrigation helps weaken Poa, and how targeted inputs can manage high-Poa areas like shaded or poorly draining greens. Rick shares how cultural practices and selective spot treatments can reduce Poa pressure, especially as changing climate conditions make maintaining Poa more difficult. Stay Informed with
