The primary influence of soil health on plant growth lies in its effect on nutrient availability, water retention, and root development. Healthy soils are rich in organic matter, fostering microbial activity that enhances nutrient cycling. This bolsters overall soil fertility and ensures plants receive essential minerals for growth. Furthermore, well-structured soil improves aeration and drainage, promoting strong root systems. Hence, maintaining soil health is vital for sustainable agriculture and ensuring robust plant populations, which are intrinsic to ecosystem stability.
