Comparing Physical and Chemical Soil Properties Measurement: CNAL vs. NSSC

Abstract

In this study we compared soil characterization data from the NRCS Soil Survey Laboratory (SSL) at the National Soil Survey Center (NSSC) and Cornell Nutrient Analysis Laboratory (CNAL) for paired analyses of selected soil chemical and physical properties. This assessment of soil characterization data generated by CNAL and NSSC, as determined using simple linear regression, demonstrated substantial agreement between the two laboratories. The results can help local practitioners obtain data more rapidly through local university‐based laboratories, while still allowing comparison and statistical analyses with data provided by the national soil survey laboratory.
