Client Testimonial or Staff Bio

John Doe

Doe found it difficult to grow tomatoes in his backyard garden for several summers in a row. After wanting answers, Doe sent his soil sample to the CSU Soil, Water and Plant testing lab. Thanks to the technicians at the lab, Doe figured out he had too much salt in his soil and was able to make a plan of the next steps he could take to improve his garden at home.

“Thanks to the lab my tomatoes grew tall and fruited this summer,” Doe said.
