Question

Answer

Low conductivity water in irrigation

Introduction:
Irrigation is the artificial application of water to the soil for agricultural purposes. The quality of irrigation water is an important factor that affects crop production. One of the important parameters to consider while assessing the quality of irrigation water is electrical conductivity (EC).

Definition:
Electrical conductivity is the measure of the ability of water to conduct an electrical current. It is expressed in units of micro mhos/cm.

Low conductivity water:
When the electrical conductivity of irrigation water is up to 250 micro mhos/cm, it is called low conductivity water.

Importance of low conductivity water:
Low conductivity water has several advantages in irrigation:

- It does not contain high levels of dissolved salts, which can be harmful to crops.
- It does not cause soil salinization, which can reduce soil productivity.
- It does not require expensive treatment before use in irrigation.

Effects of high conductivity water:
High conductivity water can have several negative effects on crop production:

- It can cause salt buildup in the soil, which can reduce soil productivity and limit crop growth.
- It can cause plant stress, which can lead to reduced crop yields.
- It can cause waterlogging, which can suffocate plant roots.

Conclusion:
In conclusion, low conductivity water is an important factor in crop production. Farmers should test the quality of their irrigation water and take appropriate measures to ensure that it is of the right quality for their crops.
