Soil Chemical and Physical Analyses
|
| ASL
provides comprehensive analytical services in the area of soil analyses,
including fertility testing and environmental analyses. ASL also
provides laboratory testing of soil samples for NRCS Nutrient Management
Plans (see SNMP in table below). Standard methods are used for all chemical and physical tests, including
pesticide
residue analyses.
ASL participates in the North American Proficiency
Testing Performance Assessment Program (NAPT-PAP).
For information on soil sampling techniques, please contact the local county
extension agent in your area.
NOTE: ASL does not provide interpretations or
recommendations for soil analyses. Please contact
your local county
extension agent.
