The Soil, Water and Forage Analytical Laboratory (SWFAL) was established by the Oklahoma Cooperative Extension Service to provide soil testing, plant, animal waste and water analyses for the State of Oklahoma and anyone who needs agricultural testing services.  Each year over 60,000 various samples are submitted for analyses by thousands of farmers, ranchers, homeowners, consultants, governmental agencies and researchers.  Recommendations are made based on many years' field calibrations conducted in Oklahoma.  SWFAL provides valuable information that helps lab users to protect and utilize their soil, water, animal manure, and forage resources efficiently and effectively.
