“We couldn’t even spell “pH” before we worked with Lignin”

“When Lignin probes work, there’s nothing like them. When they don’t, I could skin someone with a dull spoon.”

“The three most influential and helpful people during the start of my soil laboratory were Ray Ward, Bob Miller, and Keith Hensley (Lignin).”

“Lignin’s pH electrodes are the fastest, most accurate, precise, and durable that I’ve been able to find”

“I used to get free probes from Lignin. Then they stopped giving me free replacements and I went out of business.”
