| Natural drainage and depth to gley and hence to water table after wet periods |
Poor
<30cm |
| Potential rooting depth, texture, and limiting layer |
>30cm clay loam on silt loam |
| Available water capacity |
75mm |
| Infiltration rate |
Slow
|
| Permeability rate |
Slow if compacted |
| Susceptibility of topsoil to pugging and compaction |
Extremely high |
| Unfavourable soil characteristics |
Heavy topsoil - easily compacted and difficult to manage in wet conditions slow infiltration if compacted- slow permeability |
Soil Management
| Artificial drainage: drain spacing |
19 20-40m |
| Cultivate when moist to avoid: compaction |
