Discussion paper. What are the likely benefits of draining this area? How and why it occurs How to recognise it in the paddock Managing the problem What is the best practice? What is the best practice? Once a waterlogging event has passed, plants recommence respiring. Subsurface drainage - Once you have taken care of the surface drainage, you may need to look at improving the drainage through the soil profile.
Meaning of water logged soil: Submerged soils are soils that are saturated with Soil structure: Continuous water stagnation destroys the soil. Waterlogging occurs whenever the soil is so wet that there is insufficient oxygen are very susceptible to water erosion and are prone to soil structure decline if. Waterlogging may be a natural condition of the soil, but can worsen with deterioration in soil structure; It occurs when rainfall exceeds the ability of some soils to.
As long as soil conditions are moist, the older roots close to the surface allow the plant to survive.
forestry Soil structure and water logging
Raised bed cropping: Over the past decade, extensive research efforts have been directed towards the factors that contribute to waterlogging and soil structure decline under broadacre cropping regimes.
Cost of waterlogging and inundation Most data on the cost of waterlogging and inundation are from the Upper Great Southern see McFarlane et al.
Options might vary from shallow surface drains ie.
How do I manage waterlogging
Waterlogging in some years and some environments in the high rainfall areas of poor trafficability; loss of nutrients; soil structure decline.
Since an oxygen decrease is one of the first effects of soil waterlogging, most is the gas diffusion coefficient in the soil, which depends on texture, structure.
Most often, waterlogged conditions do not last long enough for the plant to die.

Improving drainage from the inundated paddock can decrease the period at which the crop roots are subjected to anaerobic conditions. Subsurface drainage aims to take away only the surplus water in the soil. What is causing the waterlogging problem? Fact Sheets Waterlogging.

Drainage can be improved on many sites and is the first thing to consider once a waterlogging problem has been identified.
Waterlogged and inundated areas contribute recharge to saline aquifers, are very susceptible to water erosion and are prone to soil structure decline if cultivated or stocked when too wet.
