Soil texture plays a crucial role in plant growth due to its influence on several key factors, especially water retention and nutrient availability. The size and arrangement of soil particles determine how much air and water can be held in the soil, which directly impacts the roots' ability to access these essential resources.

For instance, finer textures, such as clay, can hold water better but may also lead to drainage issues, whereas coarser textures, like sand, provide excellent drainage but do not retain water and nutrients effectively. When soil has a balanced texture, it achieves an optimal environment for plant roots to thrive by ensuring adequate moisture levels and nutrient supply.

Understanding this relationship helps in selecting appropriate crops and soil management practices tailored to specific soil types, ultimately leading to improved agricultural outputs. The other options do not accurately reflect the nuanced relationship between soil texture and plant growth, oversimplifying or misrepresenting this vital aspect of soil science.
