what are the main causes of water logging
Answers
Explanation:
Waterlogging occurs when roots cannot respire due to excess water in the soil profile.
Water does not have to appear on the surface for waterlogging to be a potential problem.
Improving drainage from the inundated paddock can decrease the period at which the crop roots are subjected to anaerobic conditions.
While raised beds (see Raised Bed Cropping fact sheet) are the most intensive management strategy, they are also the most effective at improving drainage.
Waterlogged soils release increased amounts of nitrous oxide (N2O), a particularly damaging greenhouse gas.
Answer:
Waterlogging is caused by a combination of excess rainfall (for the site), poor external drain- age (runoff), poor internal drainage (water movement in the soil profile) and the inability of the soil to store much water.
