Description of soil BCBNN~~~~~A (BONSON)
| Classification | GL.SB |
|---|---|
| Profile | Agricultural soil profile The soil has been disturbed by agriculture. |
| Kind of material | Mineral The soil material is primarily composed of mineral particles. |
| Water table | Non growing season The water table is present in the soil during the non growing season. |
| Root restrictions | No root restricting layer The growth of plant roots is not restricted by any soil layer. |
| Type of root restricting layer | n/a Not Applicable |
| Drainage | Imperfectly drained Water is removed from the soil sufficiently slowly in relation to supply, to keep the soil wet for a significant part of the growing season. Excess water moves slowly downward if precipitation is the major supply. If subsurface water or groundwater, or both, is the main source, the flow rate may vary but the soil remains wet for a significant part of the growing season. Precipitation is the main source if available water storage capacity is high; contribution by subsurface flow or groundwater flow, or both, increases as available water storage capacity decreases. Soils have a wide range in available water supply, texture, and depth, and are gleyed phases of well drained subgroups. |
| Mode of Deposition | Texture | Chemical properties | |
|---|---|---|---|
| Uppermost | Fluvial These sediments generally consist of gravel and sand with a minor fraction of silt and rarely of clay. The gravels are typically rounded and contain interstitial sand. |
Medium Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL). |
Medium Acid to Neutral pH 5.6 - 7.4 |
| Below | Fluvial These sediments generally consist of gravel and sand with a minor fraction of silt and rarely of clay. The gravels are typically rounded and contain interstitial sand. |
Very Coarse Very Coarse (USDA Texture Classes: VCS,CS,S,GS,CBS). |
Medium Acid to Neutral pH 5.6 - 7.4 |
