| Depth | Horizon | Detail |
|---|---|---|
| 3 cm | LF | Oak and some Ash leaves and twigs. |
| 0 to 7 cm | Ah | Brownish black (10Yr 3/2) stoneless silty clay; moist; moderate fine to granular subangular blocky structure with ped face colours as matrix; low packing density; moderate porous; moderately weak ped strength; slightly sticky and plastic; common very fine to coarse roots; common earthworm activity; non-calcareous; diffuse wavy boundary. |
| 7 to 15 cm | E(g) | Greyish yellow brown (10YR 6/2) with many very fine bright yellowish brown (10YR 6/8) mottled stoneless silty clay; moist; moderately coarse subangular blocky structure; moderately weak soil and ped strength; slightly sticky and plastic; non-calcareous; diffuse wavy boundary. |
| 15 to 37 cm | Btg | Greenish grey (10Y 6/1) with abundant clear distinct fine reddish yellow (7.5YR6/8) mottles; stoneless silty clay; moist; moderate coarse subangular blocky structure; common large voids and earthworm channels; moderately firm soil; very sticky and plastic; few to very few fine to coarse woody rots; non-calcareous; clear smooth boundary. |
| 37 to 74 cm | BCg | Greenish grey (10Y 6/1) with common to many clear distinct fine reddish yellow (7.5YR 6/8) mottles stoneless clay; moist; moderate very coarse to strong coarse angular blocky structure; high packing density; very slightly porous. |
