2.3 Analyses of SOM and densimetric fractions
Soil samples, to determine SOM in 0-0.1-m layer, were collected at random locations within a radius of 50 to 60 m from the profile. Twenty bulk samples were collected and pooled. Additional samples from depths of 0.1-0.2 and 0.2 and 0.4 m were also obtained from the walls of the profile.
