1. What’s Wrong with that Plant?

2. A big part of keeping a plant alive is making sure that the soil the plant is in is healthy.
Key nutrients plants need are:
Phosphorus
Potassium
Nitrogen

3. Lack of Nitrogen
Stunted plants, pale color, light green or yellow if sever
Occurs on older foliage first
For corn, the lower leaves have a yellow “v” pattern along midrib
Caused commonly by an over amount of carbon in the soil.

4. Lack of Phosphorous
Turns edge of the leaves purple and slows down growth
Cause most often by wet/cool weather needed for the plant and clay based soils

5. Lack of Potassium (AKA potash deficiency)
Appears on older leaves first, and is strongest at edge, advancing inward
Commonly found in sandy soils
