Why Is Irrigation Important For Growing Crops?


Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.



How does irrigation affect food production?

– Irrigation fosters diversity in farm production. For instance, nearly 60% of all Alberta beef is fattened in southern Alberta's irrigated areas, creating employment and adding value to forage crop production. Value-added is the return to labour, land, management and capital requirements.


What are the positive and negative effects of Indira Gandhi Canal area?

The introduction of irrigation through Indira Gandhi Canal in sandy, barren and hot climatic land has caused if tremendous positive impact within a short duration, on the other hand it has led to adverse impact in the form of water logging, soil salinity, raising of ground water level, siltation of canal by sand.


Why is water necessary for irrigation?

Water helps to maintain the turgidity of cell walls. Water helps in cell enlargement due to turgor pressure and cell division which ultimately increase the growth of plant. Water is essential for the germination of seeds, growth of plant roots, and nutrition and multiplication of soil organism.


Why is irrigation important for growing crops?

Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.


What are the positive impacts of irrigation on Indira Gandhi?

(i) Preparing land development and water harnessing strategy for sustainable agricultural development. (ii) Ensuring crop and non-crop based development. (iii) Development of land and water harvesting infrastructure.


Why do we irrigate and what benefits will irrigation do to us?

Irrigation systems offer a variety of benefits. They allow for the growth of a wider variety of crops. They can be timed so that the hands-on portion of crop production is a little less cumbersome. They protect crops from irregular and dry weather conditions.


What are the positive and negative impact of irrigation?

There are many positive impacts of irrigation on the environment. Among the negative impacts which appear in the mentioned spheres prevalent impacts is the danger of waterlogging and salinization of soils and waters, rise in groundwater table, spread of water born diseases, pollution of waters and many others.


What is a negative effect of irrigation?

Adverse Impacts

The reduced downstream river flow may cause: reduced downstream flooding. disappearance of ecologically and economically important wetlands or flood forests. reduced availability of industrial, municipal, household, and drinking water.


How is irrigation good for the environment?

Installing an irrigation system in your yard is a great way to help the environment, since irrigation systems provide the water that sustains agriculture and flora and fauna. Think of an irrigation system as a reservoir that collects rain and groundwater and distributes it evenly at a chosen time and place.


Why is irrigation good for soil?

Cooling the ground and atmosphere via irrigation creates a suitable environment for crop growth by preventing your soil from drying out as quickly. Properly installed irrigation systems dilute salt and chemicals in the soil that are counterproductive to healthy crop growth. Soft-land is easier to plow than hard land.


What are two negative effects of Indira Gandhi Canal irrigation?

However, the environmental impacts of this new canal water supply have mainly been negative. The economic boon gave rise to many environmental implications such as water logging, deterioration in quality, soil salinity, siltation of canal by sand, water born diseases.


Is irrigation good or bad?

While bad irrigation can result in excess nutrient loss, good irrigation can reduce nitrogen loss to ground water and improve soil quality. It also has the potential to improve river flows, and reduce the risk of erosion. FAR research is providing scientific data tp show just how can irrigation benefit the environment.


How did irrigation improve agriculture?

Water applied as irrigation allows for crop production in arid regions and supplements soil moisture in humid regions when growing season precipitation is insufficient. Irrigation has enhanced both the productivity and profitability of the agricultural sector.
