I am an Assistant Supervisor of Environmental Testing. That is the official title. I work in a service lab at Penn State University testing plants, soils, composts, biosolids, manures etc for nitrogen/carbon content. We also do other nutritional testing for these samples. Our lab is used by people all over the world in farming, greenhouses, orchards and researchers to determine how much and what type of fertilizers are needed to be efficient or for various research projects on how to grow a better, bigger plant. *shrug* I guess that is the easiest way to describe it.
