D.Soil degradation and nutrient depletion

Explanation:

Over time, monoculture farming can lead to soil degradation and nutrient depletion. Since the same crop is planted year after year in the same soil, it continuously drains specific nutrients that the crop requires, without giving the soil a chance to regenerate. This can result in poorer soil quality and lower yields over time. The lack of crop rotation further exacerbates the depletion of nutrients like nitrogen, phosphorus, and potassium, which are vital for healthy plant growth.

The other options are not typical results of monocultur...
