Question

water logging was observed in a field of a farmer. what reasons would you give to the farmer such that he improves the drainage system and avoids the water logging in his field?
if you don't know than don't write please ​

Answer 1

Answer:

• significant land degradation threat across much of south-west Victoria
• Vast areas including the Heytesbury Soldier Settlement and the Victorian Volcanic Plains represent landscapes significantly affected by waterlogging
• Is a significant problem for dairy farmers during winter and early spring where soils can remain waterlogged for considerable periods
• Causes poorer pastures, both in growth and quality

• Makes it harder and more unpleasant to farm, particularly for dairy farmers:
• those jobs with critical timing (such as silage making and crop sowing) can be upset
• tractors leave deep furrows in paddocks when feeding out
• cows pugging pasture to the point where they require a full renovation
• Waterlogging is also a major constraint to grain production in the region

Answer 2

Answer:

Management options for waterlogging

Suitable options depend on the severity, position in the landscape and land use. You can adapt crop or pasture management to the waterlogged conditions, reduce the waterlogging on-site, and reduce surface water flow to the susceptible site. We recommend a combination of these options, as part of a whole-farm water management plan.

Options include:

1. do nothing: just avoid waterlogged areas when seeding, spraying, and harvesting; not normally recommended
2. use more-tolerant crops or pastures, and use suitable agronomy
3. alter nitrogen management to suit the waterlogged situation
4. use shallow surface drainage on flat waterlogged or inundated areas
5. use surface water management upslope, to divert surface water flows
6. use raised beds on high susceptibility flats, with shallow surface drainage
7. in high rainfall areas and irrgation areas with clay soils, use mole drains.
