Title: (Optional) Explain the effects of water pollution on agricultural production.
Course: Ecology and Environmental Management (18003-18) > Section: Protecting the Environment – Water

Explanation may include

- high salt levels—low water uptake
- high metal levels—high stress, low yields
- excess phosphorus—discoloration
- excess nitrogen—yellowing and weakness.

Process/Skill Questions:

- How do excess levels of some necessary nutrients have a negative effect on crop yields?
- What types of corrective measures and/or management practices could one implement to eliminate or minimize the effects of water pollutants on irrigation water?
- Why is it important to determine whether soils have excessive nutrient levels before irrigating? Explain.
