What are the advantages and disadvantages of irrigation?

1.5. 1.2. Artificial sub-surface irrigation

Merits Demerits
1. Reduction in evaporation & percolation loss. 1. Initial cost is more.
2. No wastage of water. 2. Quality of water should be good.
3. No wastage of land. 3. Difficult to supervise.
4. Reduction in soil erosion. 4. Highly skilled technology and manpower are required.

What are the advantages and disadvantages of subsurface irrigation?

Applicability, advantages and disadvantages of subsurface drip irrigation

  • High degree of control over water application with the potential for high uniformity of application.
  • Evaporation is reduced.
  • The amount of water can be fine-tuned.
  • Frequent irrigation allows for optimum soil moisture content in the root zone.

What is advantage of subsurface irrigation?

(1) Permanent subsurface drip installation requires less yearly labor than surface drip installation and increases the life expectancy of the system; (2) Cropping with a dry soil surface has the potential to reduce the occurrence of soil borne diseases and help control weed infestation; (3) Dry soil in the furrows …

What is the main advantage and disadvantage of irrigation agriculture?

Advantages include low costs and minimal labor. A hose and a garden hoe are all it takes to have functioning furrows between vegetable rows. Water stays in the root zone, and foliage stays dry. Drawbacks to surface irrigation include potential overwatering and wasteful runoff.

What are the negative impacts 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 are the negative effects of irrigation?

The effects may be water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigation projects can have large benefits, but the negative side effects are often overlooked. The lower the irrigation efficiency, the higher are the losses.

What are the disadvantages of subsurface drainage?

A disadvantage of subsurface drainage is that its often more costly to implement per unit area compared to surface drainage, especially for fine textured soils.

What are the advantages of flood irrigation?

Flood irrigation supplies water to a field through pipes or ditches….Flood irrigation.

Pros Cons
Runoff water can be recycled to improve efficiency Building and taking down levees is labor intensive
Side-inlet flood saves 60% of water compared to cascade Land usually needs grading to inable uniform water distribution

What are the advantages of overhead irrigation?

Advantages of Overhead Micro-Irrigation for Vegetables

  • Low precipitation rate.
  • Low operating pressure.
  • Short irrigation intervals.
  • High water and fertilizer distribution uniformity throughout the field.

What are the advantages and disadvantages of using agrochemicals?

Discuss advantages and disadvantages in using synthetic agrichemicals in forage production

Advantages of Using Agrichemicals (Benefits) Disadvantages of Using Agrichemicals (Risks)
Higher Crop Yields Contamination of crop products with harmful chemical residues
Higher Crop Quality Contamination of soils and groundwater

What are some positive impacts of irrigation?

Irrigation has direct and positive production impacts, but it also increases the productivity of complementary agricultural inputs such as land, seeds, and labor. Irrigation’s impact on the productivity of land is particularly notable.

What are the impacts of irrigation?

reduced agricultural production (Figure 3) • reduced farm income • reduced options for production • reduced access and trafficability on waterlogged land • reduced water quality for stock, domestic and irrigation use • damage to and reduced life of farm structures such as buildings, roads, fences and underground pipes …
