Which of the following is NOT a sign of sulfur deficiency?

A sign of sulfur deficiency can manifest in various ways, but high nitrogen levels are not typically associated with it. When sulfur is deficient, plants may show stunted growth, pale leaves, and poor development. High nitrogen levels do not contribute to these symptoms; in fact, they can help mask sulfur deficiency by promoting overall plant growth, which may delay the onset of deficiency signs.

Coarse textured soils and very low organic matter soils can contribute to sulfur deficiency because they often have lower sulfur content and can drain quickly, reducing the availability of nutrients. Warm and rainy climates can also influence sulfur availability in the soil; however, they are not direct indicators of deficiency. Essentially, high nitrogen levels do not align with the typical characteristics of sulfur-deficient plants, making it the correct answer for this question.
