2.5.4. Texture 4 (Loamy Sand)
No further subdivision possible
2.5.5. Texture 5 (Sand)
The sand database from section 2.4.5 can be subdivided into 5-15-100 (n=33), 5-25-60
(n=9), 5-25-75 (n=9), 5-25-90 (n=9) and 5-25-200 (n=3). None of these subdivisions
yields any further relevant information.
2.5.6. Texture 6 (Sandy Clay Loam)
No further subdivisions possible
2.5.7. Texture 7 (Sandy Loam)
The sandy loam database can be subdivided into 7-20-29 (n=5), 1-20-100 (n=5), 1-22-
100 (n=3), 1-25-60 (n=3), 7-25-100 (n=11), 7-28-20 (n=10), 7-28-50 (n=10), 7-28-133
(n=10), 7-35-60 (n=7), 7-35-90 (n=7) and 7-35-120 (n=7). The only subsets to yield any
new significant information are 7-28-50 (Rdn Vs. OC) (Figure 2.46) and 7-22-100 (Rdn
Vs. pH) (Figure 2.47).
