Welcome to American Agricultural Laboratory!
The primary function of American Agricultural Laboratory since its beginning in 1976 in Nebraska, (as Olsen’s Laboratory) has been to provide quality analytical services to the agricultural community.
Services include analysis of soil, plant tissue (petiole and leaf), nematodes, feed, fertilizer, water, manure, wastewater, heavy metals and seed germination testing.
The laboratory has developed its own Internet Client Software for ease and speed of data delivery.
The area served by American Agricultural Laboratory is both national and international.
Our laboratory is one of only two private Nebraska labs certified by DHHS for the analysis of Coliform Bacteria/E. coli and nitrate-N in public drinking water. Our laboratory also participates in many quality control check sample programs.
