How does irrigation affect water systems?
Excessive irrigation can cause contaminants to enter the watercourse or aquifers by leaching through the soil or overland runoff. Heavy soils that have low infiltration rates are susceptible to runoff if the irrigation system applies water at a rate greater than the applied water can infiltrate the soil.
What are the types of irrigation system?

- Surface Irrigation.
- Localized Irrigation.
- Drip Irrigation.
- Sprinkler Irrigation.
- Subsurface Irrigation.
- Flood Irrigation.
- Perennial Irrigation.
- Manual Irrigation.
What are the two systems of irrigation?
Surface irrigation has evolved into an extensive array of configurations which can be broadly classified as: (1) basin irrigation; (2) border irrigation; (3) furrow irrigation; and (4) uncontrolled flooding.
What do you need to know about irrigation in Nigeria?

How is irrigation used in a farming system?
Irrigation farming system is a system of supplying water to farming fields that lack sufficient moisture necessary for crop growth. This system increases water content in the root layer of soil in order to increase soil fertility and promote healthy crop growth. Irrigation can be surface or subsurface.
What are the different types of irrigation methods?
This method has three varieties: border strip, furrow, and flooding. When using bay or border strip method, the water moves along parallel thin ridges on the surface that are aligned in long strips and in the process of moving the water is absorbed into the soil.
Are there any problems with a drip irrigation system?
Drip irrigation equipment is vulnerable to several problems, such as debris, mineral buildup, and physical trauma from external forces such as lawnmowers. That’s why we offer an extensive variety of drip irrigation components; you’ll never want to find yourself with a broken system.
