No further subdivisions possible.
2.7.7. Texture 7 (Sandy Loam)
The sandy loam dataset is divided into the following subsets 7-28-20-4.7 (n=3), 7-28-20-
6.5 (n=4),7-28-20-8 (n=3),7-28-50-6.5 (n=5),7-28-50-8 (n=3), 7-28-133-4.7 (n=3), 7-28-
133-6.5 (n=4) ,7-28-133-8 (n=3), 7-35-60-7.6 (n=7),7-35-90-7.6 (n=7) and 7-35-120-7.6
(n=7).
All of the sandy loam subsets have only one nitrate concentration value and the only
databases to show a significant correlation between the denitrification rate and organic
carbon are 7-28-20-4.7, 7-28-20-6.5,7-28-50-6.5,7-28-50-8 and 7-28-133-8 (Figure 2.95 -
Figure 2.99).
