What is the characteristic of dormant grass regarding nitrogen application?

Dormant grass requires no nitrogen application because, during dormancy, the grass is in a state of rest and essentially stops growing. Nitrogen is a nutrient that promotes growth, and applying nitrogen during this period would not benefit the grass since it will not utilize the nutrient effectively. The primary function of nitrogen is to support the growth of plants, and in the absence of growth, as seen in dormant grass, there is no need for additional nitrogen input.

In comparison, the other choices imply that nitrogen is needed under certain conditions, which is not appropriate when dealing with dormant grass. Increased, frequent, or seasonal nitrogen applications are unnecessary during dormancy because the grass is not in a growth phase, making those practices ineffective and potentially wasteful. Thus, avoiding nitrogen application during this time aligns with best management practices for maintaining the health of grass areas.
