What is a common consequence of delayed fertilization in the fall for crops?

Delayed fertilization in the fall can significantly increase the risk of phosphorus runoff. When fertilizer is applied late in the growing season, it may not be effectively utilized by the plants before the onset of winter or heavy rains. As a result, excess phosphorus can accumulate on the soil surface and be washed away during rainfall events, leading to runoff into nearby water bodies. This runoff can contribute to nutrient pollution, stimulate algae blooms, and negatively impact water quality. Addressing timing and proper application of fertilizers is crucial to mitigate these environmental impacts.

The other options do not accurately describe the consequence of delayed fertilization in the fall. Increased flowering time relates more to the timing of planting and growing conditions rather than fertilization. Enhanced soil structure typically results from practices like crop rotation and cover cropping instead of the timing of fertilizer application. Improved drought resistance is influenced by various factors such as soil health and plant genetics, not directly tied to the timing of fertilization in the fall.
