| Though part of the Sangrur district suffers from a falling water table, the other part suffers from waterlogging. |
| Native to tropical America and occurring in the subhumid or semi-arid tropics, in areas not subject to waterlogging. |
| Meanwhile, land productivity is reduced by water and soil erosion, salinity, sodicity, waterlogging, flooding and loss of organic matter. |
| As the stems grow, they form hollow structures inside that allow gas exchange with the atmosphere and thus prevent the plant from waterlogging. |
| The shallow fibrous roots form a massive root system, and the plant is resistant to both drought and waterlogging. |
| Tolerance to anoxia is relevant to wetland species, rice cultivation and transient waterlogging of agricultural crops. |
