What is one potential consequence of low soil fertility?

Low soil fertility can significantly impact agricultural productivity, leading to lower crop yields. When soil lacks essential nutrients such as nitrogen, phosphorus, and potassium, plants may struggle to grow optimally. These nutrients are crucial for various physiological processes, including root development, photosynthesis, and overall plant health. Insufficient nutrient availability can result in stunted growth, poor flowering, and reduced fruit or seed production, ultimately leading to a significant decline in the quantity and quality of the harvest.

In contrast, options such as improved plant resistance to diseases, increased water retention, or enhanced soil structure are not direct outcomes of low soil fertility. While healthy soil can contribute to improved plant health, the direct relationship between low fertility and reduced yields highlights the critical need for maintaining soil health through appropriate management practices.
