No further subdivision possible.<br />

2.7.10. Texture 10 (Silty Clay Loam)<br />

The silty clay loam dataset can be divided into four subsets 10-18-100-6.8 (n=3), 10-25-<br />

60-6.5 (n=9), 10-25-75-6.5 (n=9) and 10-25-90-6.5 (n=9). None of the subsets show a<br />

significant correlation between the denitrification rate and organic carbon or pH.<br />
