Drainage ensures that the soil is properly aerated . If you have excess or standing water it can choke your crops. Drainage reduces soil and nutrient loss from runoff and can help avoid soil erosion. Drainage on hill slopes helps to reduce the risk of soil slippage.
What are effects of drainage?
Also the drainage affects the physical and chemical properties of soil where the lack of a good drainage leads to the lack of air inside the pores of the soil leading to stop the oxidation of organic materials operations and shift some soluble compounds in water to insoluble compounds which accumulate in the pores of ...
How does drainage affect the agricultural system?
Deeper drain installation ensures that salts do not rise too rapidly to the soil surface due to capillary action. Drainage also prevents waterlogging of the root zone . The amount of irrigation water to be removed is generally less in arid than in humid regions.
What is the effect of drainage on soil and crop?
So, drainage is used to control ponding at the soil surface, to control waterlogging in the soil, and to avoid salinization. Drainage is the removal of excess water and dissolved salts from the surface and subsurface of the land in order to enhance crop growth.
Is drainage good for farming?
Drainage can improve crop yields , reduce year-to-year yield variability, and provide trafficable conditions for field operations at critical times of planting or harvest. Drainage system design and management can impact crop production and have environmental consequences.
What is agricultural drainage and their importance?
Drainage systems save energy used in irrigation by controlling soil moisture . They prevent crop loss from flooding and maintain agricultural soil conditions so as to maximize yields.
What are the types of agricultural drainage system?
While there are more than two types of drainage systems employed in agriculture, there are two main types: (1) surface drainage and (2) sub-surface drainage.
What is the importance of drainage system?
Either by lowering the amount of water which passes through the structures and foundations, i.e. by reinforcing the sealing characteristics, Or by drainage, channelling the water to those parts of the structures where its effects will be least harmful .

Which soil has the poorest drainage?
The worst drainage problems typically occur in clay soils that bind together, thereby creating a dense, almost solid surface. These soils are also referred to as adobe, gumbo, caliche, hardpan, or heavy soil. Due to their tendency to be watertight, such clay soils are often used in the making of ceramics.
What factors affects soil drainage?
The causes that affect the increase in drainage may be multiple, such as a change in the precipitation patterns or climate extremes , a change in land use that allows for less infiltration and more runoff, or land subsidence that causes an increase of the water volume to be drained from the soil [9,20,21,22,23].
Which soil has best drainage?
The idea soil for most plants is loam (a mixture of sand, silt and clay). This type of soil is ideal because it allows the water to drain freely while still retaining nutrients and moisture.
What is drainage and types of drainage?
Drainage can be either natural or artificial. Many areas have some natural drainage; this means that excess water flows from the farmers’ fields to swamps or to lakes and rivers. ... There are two types of artificial drainage: surface drainage and subsurface drainage .
Why is it an advantage to have good drainage in most agricultural land?
Advantages of agricultural drainage
Provision of drainage facilitates early sowing of the crop . Agricultural land can be used for a long time without any deterioration due to damaged soil structure and salt concentration.
