Waterlogging of Soil :: Environmental, Informative,

What is it? weeweelogging is the lower in land productivity through the rise in ground weewee close to the imperfection surface, and also where the water system supply put over rises above the surface. The raised water plank results in the soils becoming swampy and air spaces in the soil atomic number 18 filled with water, and make up roots, in effect, suffocate from the lack of oxygen, limiting plant growth in those aras.Where does it go across? peelogging occurs where bad irrigation methods are used and in poorly drained soils where water cant penetrate deeply. For example, there may be an impermeable carcass stratum below the soil. It also occurs on areas that are poorly drained topographically. Worldwide, some 10% of all irrigated land suffers from water logging. Currently Victoria has 1.8 one million million ha affected by waterlogging. Waterlogging occurs broadly on flat flood plain areas or gently sloping landforms with proud rainfall and red duplex apartmen t or heavy clay soils. What causes it?Water logging is caused by extravagant irrigation on poorly drained soils, i.e. water enters the soil faster than it drains away. It occurs even off worse where there is compaction of subsoil layers where water quickly enters the topsoil but is then blocked by a water-resistant clay layer, which may occur naturally or may be bring forth through excessive use of rude machinery. Irrigation water and/or goop from canals eventually raise the water put over in the ground.What are the impacts?Water logging causesDamage to the soil structure. suffocation of Plant roots.Fall of productivity by about 20% in those areas affected.Waterlogging of Soil Environmental, Informative, What is it?Waterlogging is the lower in land productivity through the rise in groundwater close to the soil surface, and also where the water table rises above the surface.
