What can be one effect of improper fertilization?

Improper fertilization can lead to decreased plant health and yield because the balance of nutrients is crucial for optimal plant growth. When plants receive too much fertilizer, particularly nitrogen, it can result in excessive vegetative growth at the expense of root development and fruit or grain production. Conversely, inadequate fertilization can lead to nutrient deficiencies, which may manifest as stunted growth, poor foliage color, and ultimately lower yields.

Factors such as soil type, crop requirements, and environmental conditions all play a role in how plants utilize fertilizers. When fertilization practices do not align with these factors, plants may not be able to access the necessary nutrients effectively, compromising their overall health and productivity. In essence, the health of the plant directly correlates with its access to and uptake of essential nutrients, which are provided through proper fertilization practices.

The other options relate more to positive outcomes and do not correspond with the effects of improper fertilization. Enhanced crop resilience, improved soil structure, and increased crop diversity are all outcomes associated with well-managed fertilization and overall good agronomic practices, rather than those stemming from improper nutrient applications.
