2.6.8. Texture 8 (Silt Loam)
Silty loam texture can be divided into the following subsets , 8-14-73-5.5 (n=4), 8-25-60-
6 (n=3), 8-25-60-43 (n=3), 8-25-60-145 (n=3), 8-25-60-182 (n=3), 8-25-60-283 (n=3), 8-
25-60-320 (n=3),8-25-75-6 (n=3),8-25-75-43 (n=3), 8-25-75-145 (n=3), 8-25-75-182
(n=3),8-25-75-283 (n=3), 8-25-75-320 (n=3), 8-25-90-6 (n=3),8-25-90-43 (n=3), 8-25-
90-145 (n=3), 8-25-90-182 (n=3), 8-25-90-283 (n=3) and 8-25-90-320 (n=3). All of the
subsets have 3 different organic carbon values and only one pH value. Except for the 8-
25-90-6 and 8-14-73-5.5 subsets all of the subsets show a significant linear correlation
between the denitrification rate and organic carbon.
