What are the effects of water logging?

What are the effects of water logging?

Waterlogging constraints plant growth and production in the anaerobic conditions, leading to the death of certain crops and plants. Also, plant roots fail to respire as a result of the excess water in the soil profile, making them weak and either die or fall.

What are reasons of water logging and their effect?

Heavy clay soils such as black cotton soils are prone to water logging, as they hold moisture for long periods. Also, soils prone to surface sealing cause temporary water logging. Seepage and interflow from other water bodies e.g. lakes, rivers and shallow aquifers can cause water logging of adjacent lands.

What are the causes of waterlogging?

Causes of Waterlogging

• Over and Intensive Irrigation.
• Seepage of water from the adjoining high lands.
• Seepage of water through the canals.
• Impervious Obstruction.
• Inadequate natural drainage.
• Inadequate surface drainage.
• Excessive rain.
• Submergence due to floods.

What is water logging write 2 harmful effects of excessive irrigation?

Excess of water in soil leads to water logging. Sometimes, it inhibits the process of germination. Roots do not grow properly in a standing water field. Excess irrigation destroys standing crops.

How poor drainage system causes water logging and soil salinity?

The excessive use of water for crops, non-cemented canals and a poor drainage system are causing waterlogging and salinity in the area. This ultimately results in waterlogging. “The stagnant water gradually turns saline and destroys nearby arable lands.”

What is water logging condition and its effect in agriculture?

Waterlogging is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In agriculture, various crops need air (specifically, oxygen) to a greater or lesser depth in the soil.

What are the harms of excess of water in the field?

Excess water retention by a field leads to a serious problem referred to as water logging. When too much irrigation is supplied to the field, an unwanted and unnecessary amount of water accumulates in the field. This also harms plants and causes loss of crops. This also leads to wastage of water.

What are the negative effects of excessive irrigation Class 8?

What is water logging phenomenon?

The waterlogging may be defined as rendering the soil unproductive and infertile due to excessive moisture and creation of anaerobic conditions. The phenomenon of waterlogging can be best understood with the help of a hydrologic equation, which states that. Inflow = Outflow -I- Storage.

How does water logging affect soil salinity?

In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water. This is generally due to the higher rainfall, higher dilution capacity in surface waters and lower initial salt content in the soil.

What is water logging write two harmful effect of excess irrigation?

Over-irrigation leads to water loss, increases energy use for pumping, causes leaching of nitrogen and other micro nutrients, and wastes time. Crop nitrogen needs, fertilizer costs, and nitrogen losses to groundwater also result from over-irrigation.

What are the effect of excess water in plant?

What Happens When the Plant Receives Excess Water? # 1) Roots Lack Oxygen; During times of excess water, the plants roots will be lacking oxygen in the root zone. # 2) Root Growth is Stunted; The root system will stop growing and there will be no new root hairs being produced.

What are some of the effects of waterlogging?

Waterlogging can lead to: 1 Production loss 2 Poor trafficability 3 Loss of nutrients 4 Soil structure decline

What are the effects of logging on the environment?

If logging occurs along stream banks, the risk of flooding and erosion increases, as these trees help to anchor the soil in place Erosion also occurs through the logging operation itself. Large trucks used to transport felled trees travel on unimproved roads, which increases soil erosion and compounds its ill effects.

What are the effects of water logging and salinity?

Harmful effects of waterlogging and salinity are caused by unthoughtful planning of irrigation system. With respect to water logging and salinity, there are following harmful effects: Waterlogged soil provides excellent breeding grounds for misquitoes, and cause malaria. It causes loss in crop yield.

How does water logging occur in the soil?

HOW WATER LOGGING OCCURS: Waterlogging occurs whenever the soil is so wet that there’s low oxygen within the pore area for plant roots to be able to adequately respire. there’s no universal level of soil oxygen that will determine waterlogged conditions for all plants. Waterlogging is also a natural condition of the soil.
