What is a waterlogged area?

Something such as soil or land that is waterlogged is so wet that it cannot absorb any more water, so that a layer of water remains on its surface. The match is off because of a waterlogged pitch. Synonyms: soaked, saturated, drenched, sodden More Synonyms of waterlogged.

A land is said to be waterlogged when the soil pores within the root zone of the plants get saturated, and the normal growth of the plant is adversely affected due to insufficient air circulation. The waterlogged land results in reduction of agricultural production.

One may also ask, why plants die in waterlogged soil? plants die under water logged condition because soil gets fully saturated with water which leads to deficient oxygen supply to the roots and prevents carbon dioxide to diffuse away. Oxygen deficiency in roots causes a switch from aerobic to anaerobic respiration.

In this regard, what are the characteristics of waterlogged soil?

A waterlogged soil is one which is saturated and all the voids (pores) in are filled with water. A soil is unsaturated when part of it is filled with water and part with air. Water in the soil is also called soil moisture.

How do you control waterlogging?

Long term

  1. Improve soil structure and drainage through cultivation.
  2. Avoid smearing the sides of planting holes on heavy soils – or prick the sides of the hole with a fork before planting.
  3. Consider planting trees on a slight mound.
  4. Grow plants in raised beds.

How do you fix waterlogged soil?

Strategies for Dealing with Water Logged Soils Plant Cover Crops. Cover crops are an excellent way to use excess water. Go No-Till. A more long term strategy, going no -till improves soil structure to help with drainage. Add Organic Material. Subsoil. Build Raised Beds. A Note About Sand.

What is water lagging?

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.

What is the purpose of logging?

Logging. Logging is the process of cutting and processing trees to produce timber and pulp to supply the world’s markets for furniture, construction, paper, and other products. The practice of logging ranges from large-scale commercial timber plantations to individuals harvesting fuelwood.

What is called water logging?

Waterlogging is excess water in the root zone accompanied by anaerobic conditions. The excess water inhibits gaseous exchange with the atmosphere, and biological activity uses up available oxygen in the soil air and water – also called anaerobiosis, anoxia or oxygen deficiency.

How do you describe a drought?

A drought or drouth is an event of prolonged shortages in the water supply, whether atmospheric (below-average precipitation), surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days.

Why should we prevent water logging in our surroundings?

Main reason is that they provide favourable breeding conditions for many disease causing Mosquitoes and many other vectors which result in spread of diseases in the masses. Stagnant water is a best breeding ground for mosquitoes and other disease causing organisms.

What causes salinization?

Salinization is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below.

Why is waterlogged soil acidic?

Causes of soil acidity. Soil acidification occurs naturally very slowly as soil is weathered, but this process is accelerated by productive agriculture. Soil acidification occurs because the concentration of hydrogen ions in the soil increases.

Which type of soil is waterlogged?

Due to the structural properties of clay soil, the drainage of excess water from the soil is also a tedious process, which further enhances water logging. So, we can say that, water logging is common in clay soils.

Why do plants in waterlogged soil respire anaerobically?

If the soil gets waterlogged, the oxygen supply to plants can run out and the plants have to perform anaerobic respiration. The anaerobic respiration equation is glucose -> ethanol + carbon dioxide + energy. To sum this up, all cells need to perform respiration to produce the energy they require.

What are the disadvantages of water logging?

Waterlogging cements the soil, leaves the roots without oxygen and contributes to salinization. One disadvantage: When the water is stored somewhere. The mosquitoes take birth there.

How and where does salinization occur?

Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.

What happens to a plant if the ground is saturated?

Roots require oxygen to grow and function. In water-logged soils, root activity can shut down completely. If soils remain saturated for too long, most plants will decline or die. A saturated soil decreases a plant’s ability to take up water through its roots.

What is meant by drip irrigation?

Drip irrigation is a method of crop irrigation that involves a controlled delivery of water to plants through system of pipes, valves, tubing and emitters. The water is delivered from a source directly to the root zone of individual plants or to the surface of the soil.
