*1 = routine analysis + hydrometer particle size + gravel (1 fraction) + CaC03 equiv. + Ca, Mg, Na, K + CEC
*1a = same as (1) but with water: field capacity, available, hygroscopic
**2 = same as (1) but without gravel fraction
**2a = same as (1) with water: field capacity, available, hygroscopic
***3 = routine analysis + CEC
**** = Insufficient sample
# = Bray P on samples with pH<6.0
## = Not analyzed
