Soil Management
| Artificial drainage: drain spacing |
28 Mole drain above pan |
Cultivate when moist to avoid: compaction
wind erosion |

Irrigation:-
Recommended method
Application rate
Dripper spacing for continuous wetted strip
Amount and frequency
|
28 sprinkler to prevent waterlogging
28 30cm if 4 l/hr drippers used
little (15-25mm), often to prevent waterlogging |
