All are irrigation for canals EXCEPT:
- a. Saline.
- b. Hydrogen beroxide.
- c. Naocl
- d. RC prep.
The answer is c. Naocl.
Here's why:
a. Saline:
Saline water can be used for irrigation, although it can negatively affect soil quality and plant growth if used excessively.
b. Hydrogen peroxide:
Hydrogen peroxide can be used in irrigation water for its disinfecting properties, though its effectiveness is debated and may not be suitable for all applications.
d. RC prep:
This likely refers to a specific type of irrigation system cleaning solution, potentially containing chlorine-based compounds. Therefore, it could be considered a form of irrigation for canals.
c. Naocl:
Sodium hypochlorite (Naocl), commonly known as bleach, is not suitable for irrigation. It can be toxic to plants and damage soil microbial communities. While it may be used for cleaning irrigation canals or equipment, it shouldn't be used directly for watering plants.
Therefore, based on its harmful effects on plant life and soil health, Naocl is the least likely candidate for being used as an irrigation method for canals.
