Group A soils:soil with very high infiltration capacity. Usually consist of deep (> 1m), well-drained sandy loams, sands or gravels. Group B soils:soil with moderate to high infiltration capacity. Usually consist of moderately deep (>0.5m), well-drained medium loamy texture sandy loams, loams or clay loam soils. Group C soils:soil with a low to moderate infiltration capacity. Usually consist of moderately fine clay loams, or loamy clays,or more porous soils that are impeded by poor surface conditions, shallow depth or a low porosity subsoil horizon. Group D soils:soil with a low porosity. Usually consists of fine-texture clays, soils with poor structure, surface-sealing (dispersive/sodic) soils, or expansive clays. Included in this group would be soilswith a permanent high watertable
