Cereals/wheat

Wheat is most affected by nitrogen deficiency. This occurs especially during cold, wet conditions, and in well-drained soils in high rainfall areas. Light green to yellow colored plants can be commonly observed in sandy soils.

If a plant is experiencing a potassium deficiency, it will have pale green leaves with a limp or wilted appearance and bright yellow chlorosis with an apparent brown coloring along the margins of the oldest leaves. Meanwhile, pale yellow plants and uniformly yellow leaves without necrosis are characteristics of a sulfur deficiency.
